US Patent 7820420

We don't use preservatives in any of our formulas, and we source pure, unpreserved raw ingredients.

Because preservatives function to prevent bacterial growth in formulas. On the skin, they have a big impact on the bacterial ecosystem.
Shelf life

Because we don't use
preservatives, our products have a
shelf life.

The AO+ Mist is the only product that may require refrigeration due to the live AOBs. Whether you refrigerate or not will depend on how quickly you use a bottle.

Best used by:
Refrigerated: within 6 months
Room temp: within 4 weeks

AOBs can do something no other active ingredient can:

They convert ammonia into beneficial byproducts. In fact, everywhere in nature with ammonia, there's also AOBs, except modern human skin, where it was wiped out due to modern hygiene.

When we reintroduce AOBs to
the skin, they have a
"peacekeeper" effect:

• By consuming ammonia they help keep a healthy pH on our skin.

• Plus, it's byproducts help calm the skin & keep other microorganisms in check.

It's not just about skin care, it's
about skin health.

This is why our research partner, AOBiome, is dedicated to clinical research on AOBs as a treatment for skin disorders.

Our mission is to develop products that restore and nurture the skin biome. To do this, we had to develop strict criteria and processes for ingredient selection, formulation, packaging, and manufacturing.

We use AOB as our core measurement for testing biome-friendliness. Here's what that means: AOB are one of the most sensitive microorganisms on our skin. Because of this, we believe by formulating a product that's friendly to AOB means that it will also be friendly to the other delicate microorganisms of the biome as well.

We've developed a patent-pending assay that we use to screen all our ingredients and the final formula to ensure that it's A-OK for AOBs.
One of our early findings was that preservatives have a negative affect on AOB. This shouldn't be surprising because preservatives exist for the sole purpose of preventing bacteria and other microorganisms from growing in products. No wonder AOB didn't do well with preservatives, and why you won't find them in our formulas.

In theory, the motivation for including preservatives is a good one, but at the time, we didn't know what potential effect preservatives have on our skin biome. This is a new factor to consider.
This goes beyond our screening process. When sourcing ingredients, we've found many raw materials on their own already come with a preservative. We had to be very careful about our process to make sure we were always starting with unpreserved raw materials.
We develop products that nurture and feed a living ecosystem, without ingredients meant to inhibit or kill. This is why our products all come with an expiration date that's counted in weeks, not years.
We had to recreate parts of this process. We manufacture and package our products with strict criteria to ensure that they are 100% pure when they arrive at your door.

Our packaging is selected for maximal protection of the product inside, requiring us to use pharmaceutical grade packaging for products like the AO+ Mist. We include an expiration date on each product so that you know when to discard them.

Do I need to refrigerate it?
We recommend storing your mist in the refrigerator prior to first use. Refrigerating your AO+ Mist will keep it potent and active for 6 months.

Once you open your AO+ Mist, it's OK to leave it at room temperature, and keep it handy for use. After 4 weeks at room temperature, the bacteria will start to lose activity. Most people find that it takes them 3 - 4 weeks to use a bottle of AO+ Mist.

What if my AO+ Mist arrives and it's warm or hot?
While Mother Dirt shipments may not always arrive feeling very cold, they should not be very warm or hot either. The bacteria can withstand higher temps (remember they come from nature where some temperatures reach very high), but we do take precautions with our packaging to protect the product from extreme temperatures encountered in-transit (such as sitting in a truck on a hot day).

What if the AO+ Mist doesn't work for me?
We know that everyone's microbiome is unique, and as a result, not everyone will respond the same way. Let us know if it's not working for you and we'll issue a refund.

Can I continue to use soap and other products while using the AO+ Mist?
Yes. We'll never recommend that you abandon products you love. (Some of us at Mother Dirt still stick by our favorite conditioner, makeup, and natural deodorant.) We encourage you to experiment and see what works best for you. As best practice, we recommend applying the AO+ Mist as the very last step in your skincare routine, after all other products have had a moment to absorb.

Mother Dirt Shampoo and Face & Body Cleanser were designed specifically to be compatible with the AO+ Mist, and most off-the-shelf products are not considered biome-friendly. Some oils, such as coconut oil, are biome-friendly (as long as they are preservative and added-fragrance free), and will not harm the good bacteria on the skin.

Is the AO+ Mist okay to use on my kids?
The AO+ Mist and Mother Dirt products are safe for use on children and babies. Our ingredients are on each of the product pages, please feel free to run them by a pediatrician or doctor if you would like.

What if I want to remove the AO+ Mist from my skin once I've applied it?
If for any reason you would like to remove the AO+Mist from the skin, it can easily be removed with conventional soap and warm water.

Does the AO+ Mist have a scent?
The AO+ Mist has no scent.

    Been using the mist for about three weeks now and have to say it is incredible! I’ve never had the best skin but after using this for only three weeks 90% of my blackheads are gone and my skin feels and looks great! Kudos for a wonderful product.

    I’ve been using the AO+ Mist for over a year. All of my life I’ve had dry skin on my legs which I’ve treated with loads of lotion. I wish I could say that this was a miracle formula but it’s not. Perhaps if I didn’t shower or take an occasional hot tub it would work better. My skin is definitely less dry. I use coconut oil as a moisturizer and overall I feel like it is a benefit and will continue to use these products.

    I love the mist! Leading up to the point of buying it, I had noticed my sweat smelled really bad, and it didn’t used to. Also, my feet smelled very bad and I was embarrassed to take off my shoes and unleash the smell in someone’s home! The mist cured the bad smells, and I don’t need to wear deodorant. I mostly only use it on my feet and armpits.

    I’ve tried the body wash, and it’s fine. It feels light and airy, I like it.

    The shampoo I don’t like, it doesn’t lather well for me and my hair doesn’t feel great afterwards. My temporary solution is to simply wash my hair much less often, I do it just about once a week with Jason shampoo.

    I used to shower 1-2 times a day, and now with the mist, I found I don’t smell so I don’t need to wash as much. I actually skipped 2 days of showering, and still didn’t smell.

    I love the mist. I’ll continue using both the mist and the body wash.

    It’s a fantastic product! So grateful for it! For city people like me, without access to dirt, this is a savior!

    It works, but it takes a while and travel or stress can disrupt it. It takes about two weeks of mildly-smelly time before I am confident that I don’t smell too bad. Even then, I may not be comfortable in a sleeveless top raising up my arms at the office.

    I don’t use soap on my armpits, and I try to make sure my shampoo doesn’t get in there either, but I’m not religious about it.

    If I fly in a plane or go through a really stressful day, my carefully-tended microbiome fails me. I usually end up applying deodorant by the end of such a day so none of my colleagues notice the stench. Then it’s back to two weeks of gently keeping my arms by my sides…

    Still, once the microbuddies are doing their thing, everything is great. It’s worth it. I’ve been doing it for over a year. It would be easy to switch back but I haven’t, because it really is worth it. My dry-cleaning bills are lower due to not smelling like deodorant, and that basically makes up for the cost of the sprays (which last way longer than advertised).

    I have been misting for several years. I am an active 73 y.o. woman and have had dry, itchy problem skin most of my life. I shower about 2 x a week. I usually scrub with a brush and then cover myself in coconut oil, towel off and mist. My skin has never been better. I mist my scalp too. I really love the stuff! It is so great to be free of dry, itchy skin!

    “I can feel my skin breathing!” I found myself saying this over and over during the first week of using Mother Dirt products.

    I’ve been using all three Mother Dirt products for past six weeks. After only two days of using the AO+ mist the shift in my skin tone was remarkable and stunning. Admittedly, I kept looking in the mirror while running my hands over my face because my skin had never looked or felt so wonderful. Perhaps ridiculous and weird, after a compliment from a stranger, I invited her touch my face. Mother Dirt is the real deal when it comes to next level skincare. Wow.

    Prior to using Mother Dirt, I was — save for age-appropriate sun damage —happy with the skin on my face and body. My simple routine included a few loyal, handmade products that felt mostly nourishing instead of depleting. Because of this, I wasn’t hoping for clearer skin when I started using Mother Dirt — quite simply, I was curious. Over the the past few years I have devoured everything from science papers, to podcasts, to books and blog posts about the gut microbiome. I assumed, somewhat wrongly, that a healthy gut meant healthy skin. I am officially fascinated with the skin’s microbiome. Thank you, David Whitlock/Mother Dirt!

    Here’s the up close and personal details of my experience with Mother Dirt: I use the AO+ mist daily, often spraying a bit more on my face and underarms. Because of the mist, I have said goodbye to almost all skincare products, save for a few drops of rosehip oil, mostly for the aromatherapy purposes and I like to massage my face. While I didn’t use much deodorant prior to Mother Dirt, I find zero need for it now. The face/body cleanser is surprisingly all-purpose: it easily removes eyeliner with little effort, works well with a razor for shaving legs and leaves my face and body feeling clean. For me, a little goes a long way. The shampoo is the one product that I am still experimenting with to find the right amount of pumps during washes. Overall, I like it. My hair feel soft, perhaps a bit too full for my liking but I attribute that to the natural structure of my hair no longer being weighed down by conventional shampoo. I continue to use conventional conditioner but find that I need 50% less.

    I consider the price, while not my favorite part, an investment in my skin’s health and in Mother Dirt’s ongoing research and development. In that sense, it feels like a team effort!

    I developed problems with my skin after having children. I have taken antibiotics and used things like Retin-A to help treat my skin with limited results. When I read about Mother Dirt I figured it was worth a shot. I used the mist, cleanser, and shampoo for a month and tried skipping everything else. I live in a very dry climate with very dry skin and that didn’t work. I had serious flaking issues. After I adjusted my routine to include moisturizer again I had wonderful results. My skin’s appearance started to clear up and my pores looked great. I didn’t reorder because of price though and now I am having issues again. So today I reordered just the mist. It may be expensive but not having problems with the skin on my face is worth the cost!

    This stuff is amazing! I was using the toughest antiperspirant I could find. It stained my shirts, made me itch and slightly reduced the odor…but not much. Since I started using the spray, I threw out all that old stuff. No stains, no itch, no odor, none at all! Fantastic product.
    One quick suggestion: if you happen to be hairy (as I am), do not simply spray under the arms (the formula will not make it to your skin); instead, spray and use your free hand to work the liquid through the hair to the skin underneath. Do the same for any other hairy parts of the body (including the scalp, of course).

    I’ve been using AO+ for over a year and have found it that it reduces my body odor and lingering odors in my clothes. In addition, I have had problems with the hair follicles on my scalp and I seem to have less of a problem with this when I use AO+.

    I’ve used all three products; AO mist, Shampoo and Cleanser and I would consider each product as excellent. My husband has sensitivity to soaps and cleaning products and these three have been a great addition to our clean household.

    I use the AO Mist as recommended and like others will never go back to conventional deodorants. I go to the gym/studio first thing in the morning and I do a quick mist before I go and then re mist later after I shower. I consider the gym the biggest test and have seen no evidence of being offensive in that environment.

    I love the shampoo and only need to use it about once a week. When I do use it, my hair is the softest it has been in my adult life. The one downside is that I have very long curly hair and the product tangles my hair. I see that AO Biome has reformulated the shampoo and hopefully it will tangle a bit less. Even with the tangles, I love this product.

    Thank you AO Biome

    I have used the AO+ mist for around six months, and I love it. I go to the gym routinely, and the mist does a great job of keeping me from smelling like I just left the gym. I like the fact that it is all natural with no chemicals. Plus, I use it to freshen up my gym shoes on occasion. It works great at this too! You can’t do that with a deodorant stick.

    As mentioned by others, the only negative is the price. Hopefully, it will come down over time.

    Okay, I’ve been curious about this stuff for a long time but I always hesitated because of the price. It’s not that I’m cheap, but I subsist well below the poverty line.

    I suffer from problem skin and serious BO, and after much trial and error I found that the only products which *sort of* kept those problems in check were Aveeno redness relief foaming face cleanser, and Gillette Endurance 48-hour deodorant (the women’s deodorants were never strong enough for me, despite claims that they were equally effective). Both of those products are rather pricey, too. I would go through at least one of the deodorants a week. So, when there was a sale on the mist I decided to give it a try, because if I could cut back on either product it would mitigate the cost of the mist. Also, I live in Southern California and try to shower as infrequently as possible to save water.

    I got the mist last week. I took a shower and then sprayed myself everywhere. Figured I’d try it without deodorant and see how long it took before I started to stink. One hour? Two? I also sprayed my face, which was dry and flakey.

    I did not stink by that evening. IMPOSSIBLE, I thought. I went for a run, did some vigorous gardening (shoveling) in warm temperatures. Went to bed, and woke up the next day still not smelly. WHAT! Also, my skin started to feel softer. I didn’t have any new problems popping up on my skin that morning. I went without makeup and put more spray on. I also went without a shower for DAYS, which my boyfriend totally endorsed because SCIENCE. I never got stinky. I wore the same t-shirt three different times without washing it. My skin looks almost completely clear now and my skin tone looks more even. The only reason I finally took a shower is because my hair had become grungy-looking. Will even that improve with time? I guess I’ll find out. I plan to shower and wash my hair just once a week, and will see how long I can make the spray last by keeping it in the fridge. If I really can go without my expensive foaming face cleanser ($7-$8) and deodorant (~$3/week) this stuff is not really that expensive after all (I will still keep my eyes peeled for sales, though). 🙂

    My skin has never felt better and I’m saving a ton by not buying as many other products. I’ve cut out a $50/month treatment product, spent way less on deodorant, shampoo, and other cleansers, and my water bill has dropped from showering less. This product more than pays for itself, truly life changing!!!

    I always hated using deodorants, they left residues or made my skin irritated. Decided to try this and not only did it work very well by removing any odor, but my t-shirts stopped smelling as well. I never could use the same t-shirt two days in a row because it ended up smelling terrible, but after using ao mist/mother dirt my t-shirts never smell and I would recommend this product a lot.

    I started using the mist on February 12, 2016 and continue to this day. I try not to use it so much to stretch the product longer by less use and refrigeration. My number reason for starting to use the mist is I have dry, problem skin inside my ears–I stray it right inside twice a day. They have bothered me for 10 years. I sparingly use cortisone cream and does not solve the problem. The first time I sprayed it felt different and felt like it was getting better. After 10 years, it finally stopped causing me problems. I thought that it would be nice if it worked for my under arms, so I do not have to use deodorant. Maybe with more time I will stop smelling body odor. For me, it does not quite eliminate this. At least maybe, less deodorant can be used. I use it on my face and arm–yes my skin feels very different and living in a desert I still use some lotion. I would recommend anyone that has skin issues to use this product. I have bought enough for at least 6 other people to use it as well.

    For me, the primary attraction of the mist is the reduction of body odor without using sketchy chemicals and metals. Unfortunately, I find the mist to be moderately effective at best; I still have trouble with body odor. Even so, I’ve managed to substantially cut back on my showering with the mist.

    My other complaint is, like many others, the price. It’s a pretty substantial investment to keep supplied given as my results are only so-so. Perhaps if I used more, it would be more effective, but using more costs more, and I’ve got to balance those constraints.

    Loved Mother Dirt when I was using it. I had purchased a 3-month supply. The changes were gradual, but I noticed my face was much less oily yet not dry either, my pores were clear, and it eliminated any odor in my shoes and gym clothes after working out. But it’s far too expensive to continue using. At $50 a month, that’s more than all the other products I use combined. And if my wife wanted to use it too, that would be $100 a month. It just doesn’t make sense to spend that much. I get that we would save on water, soaps, and other products, but it wouldn’t add up to $1200 a year.

    I’ve been ordering the mist for several months now. I apply it on our hair (my 1 year old, 4 year old kids and mine) everyday. My 1 year old’s problem skin on her scalp is finally under control, she used to have issues with it often. Her hair was also very dry and now it looks healthy, without being oily. We only rinse our hair with water and use the mist everyday and our hair now looks healthier

    Meh. I really wanted this to work, I really did. I was an early adopter so I’ve tried the mist in its old packaging and the new. It doesn’t work. I smell – that’s the summary. I used it for three months previously with poor results (I chose to commit completely and did not use any soap or deodorant). I thought perhaps it would be better if I used the new cleanser and shampoo while I attempted to use the mist again. My poor husband had to suffer through my experiment. I smelled – he confirmed it for me. It’s my armpits that smell (despite loads of spray and applying before bed and not using any other products). I like the cleanser as a daily cleanser to use regularly but the mist is not worth the high price as it does provide the odor reducing results mentioned in the 5 star reviews. I would shell out the money if it worked but, alas, it doesn’t. Save your money!

    I started using this product when I was 17, when the product was in a small windex like bottle. At first I didn’t really notice anything, but I was very interested in using a probiotic for my skin. I was already eating fermented foods that help my gut microbiome so this seemed like something I should try. After a month of use, my body odor started to become less pungent. My skin felt better, and my face looked smoother and healthier than before. I completely stopped using soap in the shower, and my hair and skin have never felt better. Isn’t using a product like this almost like using common sense? Your body was intended to have a flourishing microbiome, but somehow, we were tricked into thinking that we had to scrub every living thing off of our skin. I now view shampoo as a well thought out marketing scheme that has no merit. I am 18 years old and I haven’t used conventional shampoo in a year, the mother dirt shampoo is different because it’s formulated to work with your skin’s microbiome and not against it. People don’t tell me that I smell like body odor all of the time. I shower in water, and then I spray my mist. While you question this product also ask this question. Is there really anything cleaner than good bacteria?

    I had problem skin from the age of 15 to 26. I used almost every over the counter and prescription treatment, and while I was eventually able to get things under control, if I ever tried to wean myself off of the face wash, creams and treatments, the problems came back with a vengeance and I was certain I’d be using the products the rest of my adult life. When I read about the mist in NY Times, I decided to go cold turkey on everything else and use mist only. After just 1 month, the difference was night and day. My skin didn’t appear as oily even though I wasn’t using any cleanser. I’m now 28 and my skins never been better! I even got my wife, who’s never had skin issues, to ditch the cleansers and moisturizers and use mist only and her skin has never felt better!

    I am a regular user of the AO+ Mist and have recently added the MotherDirt Cleanser to my routine. I have disappeared from the over-priced chemical loaded department store makeup counters and I am very pleased with the feel and look of my skin from my use of MotherDirt. I am also taking probiotics regularly and I am grateful for finding these products.

    I was tired of washing off my natural oils only to replace them with store bought. My hair was getting finer and thinner. I started washing my hair once a week and if I showered more just rinsing it. The improvement was immediate but I needed more. Along came the mist. I started using it in 2014 just after the New York Times article. It was the missing piece. I felt clean without ruining my skin balance. I still use a crystal deodorant after a shower or extremely physical work day but over time I tend to use it less often and to smell less. (I think some of our skin needs a variety of biomes). My skin feels good, healthy, soft though I do lather on coconut oil and I use Bare Minerals make up for my vanity. I tried the original cleanser and shampoo. I liked the cleanser, the shampoo was ok but left my ends a bit dry. I had to make a financial choice and chose the mist. I’d like smaller sizes of both cleanser and shampoo – there was always a lot left after expiration. Thank you for a revolutionary product. I looked forward to the developments going forward. All the dealings I have had with AO+ have been with caring, concerned humans who inquire and listen. In grateful appreciation Nancy

    I have very dry sensitive skin so I have been very limited in what soaps and moisturizers I can use, so I’ve struggled to clean and moisturize for a long time. Since using AO+ mist (over 1 year) I’ve seen many improvements with my skin and my moisturizers seem to be more effective. On my face, I have much smaller pores, the dryness around my nose is gone, and my skin is much better moisturized. I use it everywhere and have found I’m not suffering from winter dryness or “scales” on my shins anymore. While I do shampoo frequently because I use styling gel, I still use AO+ on my scalp and it helps my scalp from being itchy and flaky.
    I have purchased some for my daughters and they have seen good results as well.
    I have tried the cleanser to some disappointment…it works well if I’m not very dirty but I’m a landscaper so I get DIRTY and it doesn’t do the job, so I just make sure to re-apply the mist every time I wash.
    Although I like the new bottle, I am concerned about all the additional packaging and would prefer something less wasteful. I would echo other reviewers concern about the cost…It is to the point where I really have to think about when and how much I purchase at a time.

    I have a friend who does gut research related to sepsis and learned about how re-populating the gut with bacteria when antibiotics have failed actually has a high success rate of curing the infection. There was an article recently suggesting lack of exposure to bacteria may lead to higher incidence of autoimmune diseases.

    SO when I read the ny times article “…no soap, no shampoo… experiment” I was very interested.

    I’ve consistently used the spray 1-2x/day 90% of the time for about half a year. I use natural soap and shampoo/conditioner about. 3-4x/week. I have noticed having less body odor even without deodorant, and my skin is less dry probably cause I use less soap. The chicken skin on the back of my upper arms hasn’t gone away but seems to be improving with consistent moisturizing with coconut oil.

    I had tried a lot of different products, including the hardcore prescription stuff, to try to help issues with my overall complexion and nothing had really given me good results. That changed with the AO Mist, which I have been using for about a year and half now as the only product I use on my face. Any problems are much rarer, and even when they do occur they’re nowhere near as severe as they used to be. Moreover, my overall complexion hasn’t been this good in 10 years as my pores are smaller and my skin feels softer. Not only has it replaced my other facial products, but my deodorant as well and it’s no longer necessary to shower daily. Highly recommend this product if you’ve struggled with skin problems and want a product that doesn’t leave your skin feeling unnatural due to an overuse of chemicals.

    Saves all the time, much better skin. I regularly ask, “hey do I smell” as a way to introduce a conversation about MotherDirt. My skin feels great, I rarely shower (only when covered in grease and dirt from adventure). I started using more recently (from 4-10 sprays daily to 10-30) and it seems to really be a much better experience. Spot on product, a bit lower price point, and less packaging would be great, and improve adoption.

    I use the mist along with a very small amount of deodorant and I’ll tell you, you will never have to worry about underarm smell. I’ve been using it for about 9 months and love it. I’m a customer for life!

    I really like these products. I didn’t notice a huge initial change (plus my skin wasn’t too bad to begin with), but over time, my skin has definitely improved and looks much clearer, especially on my back, etc (and there’s been a marked improvement there). I can even use in lieu of deodorant and it actually works.

    I have been using the mist for five months now and am having a great experience. The science really makes sense to me, and I know most cosmetic products out there are foreign to our bodies and cause plenty of problems for humans. Along with using the mist, I cut back on showering(twice a month plus a few rinses) and use deodorant(all natural deodorants) less every month(twice a month now). It takes some time for your body to adjust and for the mist to be enough to keep you feeling clean and not smelling bad. I would say after about two months is when my body started to normalize. I had BO pretty regularly the first couple of months, but now it is rare, even with working out several times a week. Along with the mist, allowing your underarms and other body parts the chance to dry after sweating helps keep the odor away. If my underarms do smell, I can spray on some mist and that takes care of it right away. Be patient during those first couple of months, use the mist regularly, and your body will thank you for not dumping chemical laden cosmetics all over it!

    Been using AO Mist since it came out or since I first read about it in NY Times back almost 2 years ago I think. It works as far as I can tell. Hard to say since I haven’t done any lab tests but the problem skin is gone on my hands. I haven’t put soap on my body in almost 2 years (I still wash my hands with soap though not anti-bacterial). Sometimes I’ll spray the mist on my hands but usually I reserve it for my body.

    It kinda sounds weird and gross (and might be kind of embarrassing to admit) but actually I think our bodies are meant to be treated this way. No one has yet to tell me I smell bad which is a good thing – and I’ve asked. Someone even told me I have great skin. Hmm OK. 2 years and people still want to hang out with me I guess it’s a successful experiment.

    It’s a bit on the expensive side maybe but I keep coming back so perhaps they got me with the supply/demand thing 🙂

    I decided to give this a try after reading about it last year. Not even through my first month and I’ve noticed that I no longer need lotion for my face. My complexion is amazing and pores are drastically less visible. Prior to using this my skin always felt tight and dried out after drying off from a shower. Happy to say this is no longer the case.

    I’ve been waiting for a product like this for years. I’ve always suffered with my skin. When I was younger, I tried every prescription available to find some comfort. They all failed, and I gave them all up in favor of simplicity. I actually gave up soap and all cosmetic products years ago on the advice of my doctor, who said that stripping the oils from your skin makes things worse. I’ve been bathing with nothing but olive oil and water for years and was pretty happy with my regime, so I think that a lot of the positive effects people report are actually just from ditching all those products, so don’t be afraid to do that! However, the mist brings things to the next level. The effects are not immediate or miraculous, but diligent application will make you feel more comfortable in your own skin than you ever thought possible, especially on hot and sweaty days. My issues are now manageable using the mist but also combined with a careful diet and health regime. If you’re looking for a cure by itself, you’re going to be disappointed. It is expensive. If I had all the money in the world, I would use it more liberally, but as it is I just restrict myself to the sweaty areas and the problem areas, and I’m able to make my bottle last. As for deodorant, no matter how much I sprayed I still got pretty stinky, but I’m also very hormonal, so I just use a paste of baking soda with coconut oil, and no matter how hot ans sweaty I get, there is no smell whatsoever, so there is a natural alternative to antiperspirant. The baking soda does kill the AoBs though, so don’t bother misting under your arms if you’re going to use that also.

    I’ve had a great experience with the AO Mist in my 2 1/2 months of using it. I’ve been able to stop using deodorant completely. I spray 1-2 times a day but if I forget for a day I still smell fine as long as I don’t do a heavy workout. My complexion looks noticeably clearer. I’m a huge fan of the mist and plan to keep using it. One container last me 1 1/2 – 2 months so I keep mine in the fridge.

    I started having problems with my skin a few years ago and was convinced that the only relief that I could get was from the chemically made products that my dermatologist peddled onto me. Essentially steroids for your face, they were extremely expensive and typically I was spending a minimum of $100 every two months to treat my skin.
    I read an article in Bloomberg Businessweek and it was a feature about Motherdirt. I have to admit that I was enamored right away due to what I had read in the article and ordered the product right away. I have not tried the shampoo and facial cleanser mainly because I have a certain budget and use it strictly for the Mist. My wife and I have even gifted the Mist to family and friends on occasion.
    I cannot even describe in this review how well this product works in maintaining healthy skin, the best description is in the article that I read. I am a big proponent of this product for anyone who has any insecurity regarding their skin.

    The only downside of this product is the price, which I hope will slowly go down as it becomes more popular (fingers crossed!). Aside from that, I would give it 5 stars.

    The rest is all good. I’ve been using it for months (about half a year now) and in that time have cut down my use of soap and bodywash in the shower almost completely, as well as deodorant. I’ve also cut down the amount of showers I’m taking, averaging about 1 every other day where I used to shower every single day.

    The most extreme example of the product’s usefulness was recently when I moved into a new house and the hot water heater immediately broke. I was stuck without hot water (and without a shower) for 3 whole days until a new water heater could be installed. Luckily I had a bottle of AO+, which I applied generously a couple times a day. My coworkers were shocked to hear I hadn’t showered in 3 days since I didn’t even smell bad.

    All in all I’m very happy with this product and hope it will become more popular and mainstream so the price can come down.

    As a man, I am not into frilly soaps and lotions. So I really appreciate the natural approach AO+ Mist takes to health and cleanliness. Most days I just shower with hot water and spray with the AO+ Mist. It leaves my skin feeling smooth and odorless. It makes me feel more natural and in touch with my body. I’ve been using it now for months and will keep doing so indefinitely.

    Great product. Soft clear skin. I haven’t used deodorant and used limited soap on target areas of my body for the past 12 years. I have very sensitive skin and I have always worried about all the (unknown) chemicals that go into regular skin care products. This product cleared the skin on my back and chest and made those area soft and smooth. I also use it on my feet and it has somewhat (but not completely) reduced the level of my my smelly feet. I haven’t used it much on my face or hair but after reading the reviews I am going to try it. I don’t sweat very much and am not a person with a lot of body odor (except my feet) so I wasn’t worried about whether I would smell worse using the product but for me the main things I liked about it was the soft clear skin it created on my body. I also spray it in my ears and sometimes nose (I dont think you’re supposed to do that but I do). It has helped reduce the dirt that grows around my ears and made my nose clearer in winter.

    I really wanted to like the spray better–I love the idea of it, but I have to say that after over 5 months of use, I believe that it is overpriced and less effective than I had hoped. It works quite well on my face, and I no longer need to use lotions or soaps on my face. It’s much less effective in my armpits, and even with additional spraying, I have some BO by the end of the day. It’s not very effective on my head (possibly because I have long hair & it’s hard to get it onto my scalp), but it works pretty well on my feet and private areas. I liked that I was able to cut down on showers, but I still have to use a washrag at least daily to wash all the areas mentioned above. I liked that I was able to use fewer products, but just can’t afford to keep paying the price, and certainly couldn’t afford it for my whole family. Fun experiment, but sadly, not super effective, and not affordable. I also didn’t feel like there was enough support or guidance, as using the spray tends to be a pretty major lifestyle change for most people.

    I LOVE the mist! I suffer from dermatillomania… a compulsive need to pick at my skin. However, if my skin looks great – I don’t have anything to pick at.

    Been using AO+ with the cleanser/shampoo since June ’14, and completely cut out soaps and lotion without downsides. The mist does work for me. I don’t have skin issues and don’t sweat much and never used deodorants, but my skin feels good in summer and not dry in the NE winter. I also shower and do laundry less frequently now. That mitigates somewhat the cost of the product. By keeping the mist in the fridge, and misting lightly in between showers, I can also extend the life of each bottle. I am now preaching to relatives and friends and counseling patience, as 2-4 weeks may be needed to tell whether it is working.

    I have been using the AO+ Mist for about a year now and it has made a huge difference in how my skin looks. It’s smoother, softer, brighter and my face has cleared. I’ll continue using this.

In a world where we kill by off our good bacteria with medications and harsh chemicals, this is a must-have.

    At the behest of my body, I had already been years into ridding my house of chemicals when I found AO+ Mist. I loved the theory, was skeptical about its effectiveness, but decided it couldn’t be worse than any products, however gentle, I was using. My biggest concern was that I’d stink. Again, I was willing to try because I was desperate for a clean solution that wasn’t in some way irritating my body (dry skin; scent headache, even with the plainest, simplest, gentlest soap, shampoo, and conditioner on the planet).
    In September, I began misting and haven’t looked back. There was a transition period when I wondered if misting was “working.” Since I’d bought a 3-month supply, I just kept faithfully misting. Slowly, I noticed that my skin was smooth and unirritated. Then I noticed that I didn’t smell like any of the unscented products I’d been using. I smelled like nothing, I guess. I smelled like…me. Quite pleasant, actually.
    My regimen is no shampoo, no conditioner, just AO+ Mist morning and evening. I shower briefly once a week using an exfoliating glove with water. My partner is the only one who knows what I do (and don’t do) and can’t believe the results.
    My challenge is armpit odor, so I still apply the 72-hour deodorant I’d been using.
    I believe AO+ Mist has benefitted my overall health, but I can’t explain; it’s just my experience. I’ve discovered that my sensitive skin is happiest dirty, for which I’m deeply grateful.

    I was intrigued by the ‘no deodorant’ approach. Anti-perspirants used to be fine until my underarms started sloughing skin. Went to a mild deodorant only; it worked for about a year then the same sloughing action started. What the heck? Enter the Mother Dirt story headline of the man who hadn’t showered in — I don’t know — 300 years or something. $50? Yikes! But I ordered one AO+Mist without my wife knowing ($$). When it arrived I used it immediately. It seemed to work. As a test, I wore the same poly/cotton athletic T-shirt for three (yes) days. I folded it up and put it in my drawer. I pulled it out and had my wife do the sniff test. “Is this clean?” “Yes, it smells fresh.” “I’ve worn it for three days.” She didn’t even gag!
    By keeping the spray in the refrigerator and using only once per day (except for workout days), I’ve been able to stretch a single container to almost six weeks. The microbes may be unhappy at living in the cold, but once applied, they’re warm, cozy, and busy. It is a great product; just have to work it into the budget.

    I was really intrigued by the AO+ Mist and was happy to see the cleanser offered as well. So far they have not disappointed. I’m on a constant quest for natural skincare and everything about this just made sense. I’m a month in and it’s crazy that my skin is so happy with so little effort. What the cleanser and mist have done for my chest and back are nothing short of a miracle! I haven’t seen results like this with any other product (and I’ve tried what feels like thousands of them)! My showers are shorter and I have less products to juggle. It’s definitely on the pricey side, but if it saves me from spending money on typical treatments it’s not that bad—and having a natural treatment that works is well worth the money. I haven’t tackled the smelly parts yet, but have noticed my underarm razor burn is gone just by using the cleanser. I’m so thankful I found these products!

    It’s good. I love living without the constant use of soap and deodorant. I have noticed that my axillary odor is different now, somewhat milder. Sometimes it is nearly non-existent, some days it occurs in a typical body odor way. I am using the cleanser under my arms every few days, but there seems to be no correlation between use and potential odor days. Using the Mist on my face has been great—I have used no soap since beginning AOMist, my face is not vacillating from oily to dry. I have used soap for my under arms because I exercise pretty vigorously or have experienced “stress sweat,” but I would say it is only once a week or so. I think the best thing about it is the promotion of a natural biome and a rejection of the hyper-clean excesses that too many people accept as the default.

    I ordered the AO+ mist during the buy two, get one free offer you had before Christmas. Over the past few years, I have transitioned from using all kinds of harmful products (clinical strength anti-persperants, all kinds of serums and lotions with chemicals and ingredients I can’t pronounce, the works) to the polar opposite (no-poo, all natural products). When I ordered the mist, I had just started the water only method for my hair with pretty good results, and had recently decided to take the plunge into no deodorant at all. I currently use the spray under my arms, on my face, and on my scalp; each of which are described below. Under my arms: I tried several natural deodorants and found that they didn’t work very well, or irritated my skin after just a few days. One of my co-workers doesn’t use deodorant at all, so I decided to give it a try. I had a couple rough, smelly days, but I was determined to stick it out. Over the past month and a half or so, my natural “odor” has slowly lessened to the point that I shower with water only every day, and only use soap about once a week after my long run days. I still have a musky odor after the gym, but I’m okay with that, and it seems to be more mild than my post-workout smell even with the natural deodorant. My husband is nice enough to smell me when I ask him to, just to be sure, and while he has told me that I smell earthy on occasion, he assures me that it is not offensive. When I first started using the mist only, I did a lot of research into what makes people smell bad and what I could do to minimize my odor. While I haven’t given up garlic or onions, I have added a green smoothie for breakfast and lots of veggies with every meal which I’m sure is helping. The spray itself is not enough by itself to keep me odor free, but the overall effect of healthy lifestyle choices and the mist is that I don’t need deodorant every day. On my face: I have always had fairly good skin with only the occasional break out if I eat certain foods or have monthly hormonal changes. What I do have a problem with on my face is dry skin, especially around my nose and chin during the cold months. I have tried EVERYTHING to help with the dry skin which can be very painful, especially around my nose. Some things offer temporary relief, but I was incredibly surprised and delighted to find that the AO+ mist has helped get rid of the dry areas almost entirely! I wash my face with water only, use a small amount of Argan oil to moisturize, then mist. My plan is to finish the bottle of Argan oil I am now using, and see if my skin can tolerate the mist alone and maintain the results I’ve had. The mist hasn’t made my occasional break outs better or worse, but I suspect that they are caused by hormone changes anyway. On my scalp: After losing a lot of hair due to an autoimmune disease, I tried everything from Rogaine to Nioxxin to horse shampoo to try to restore some of my hair, or at least make it look a little bit thicker. I eventually realized that these products were doing more harm than good to my hair and scalp, so I switched to a natural cleansing conditioner which I was very happy with for a few years. I eventually learned about the water only method, and decided to try it beginning this past November. My hair had a minimal transition period, and looked much thicker. I did however have some dry scalp issues which I tried to alleviate with essential oil sprays, coconut oil, and various hair masks concocted in my kitchen. These things offered temporary relief, but the trade off was greasy looking hair, and the dry scalp always came back. I had been using the AO+ mist on other parts of my body with good results, and when I opened the box of a new bottle, I noticed that the scalp was one of the areas highlighted in the inside cover of the box as an area to use the mist on. I decided to try spraying it on my scalp after each shower. It has only been a couple weeks, but my dry scalp is gone! Overall my experience with the AO+ mist has been great. My hair and skin are not perfect, but they are better than they were when I was using all the “normal” products on them. I smell bad after the gym, but I smell fine at work and no one knows that I don’t use soap every day and I don’t wear deodorant. I’m going to try spraying the dry skin on my hands to see if the mist will work on that too. I’ve been keeping my two younger sisters updated with my progress, and they have both started the no-poo hair care method. It’s only a matter of time before I get them to try AO+! I love the product and can’t wait to see what happens as I continue to use it!

    I stopped using cleansers and body washes about two years before trying this product, so I am more confident to attribute the results I saw to the product itself. I live in a region with very hard water and it irritates my skin every winter causing me to space out showers and limited my time in the shower. After suffering the flu and spending far too much time in the shower trying to alleviate my flu symptoms, the skin on my back started to have issues. I figured avoiding the shower on my back for a month or so would help, but the damage was done. I tried two topical oils that were supposed to settle the skin, but saw no difference, and that’s when I broke down and tried AOBiome. In about a month I saw improvement. Everything settled, and full results were seen in three months.

    At first, I purchased just 1 bottle of AO+ Mist cautiously for sheer curiosity if for nothing else. I have read some bold claims about naturally reducing body odor with this product, this specifically interested me.

    In terms of cosmetic products, deodorant sticks were my old weapon of choice. However, they only do so much, yes you might get a fragrant smell of “fresh winter snow flakes” – but how toxic is it? In the end they all only mask your sweaty odor instead of eliminating it, and never for long enough. Most deodorant sticks all use the same “active ingredient” anyway. And as I understood it — they literally clog your sweat pores to achieve the desired result. I don’t know about you, but that does not sound healthy.

    My perpetual aim is to use the least abrasive and least invasive products. I used AO+ Mist for 1 month. During that 1 month period I noticed two surprising effects, which I did not expect. It helps with my skin and hair problems. I noticed my skin looked clear and healthy. Not to mention, for that 1 month I forgot about any problems that I had with my hair. After that month ran out, I did not reorder and within 1 week all my old problems came back. And yes, it definitely did reduce my sweat odor. For a product that is sold in the “cosmetic” category it deserves a higher level of recognition. So at the end, here I am, typing this review and ordering more AO+ Mist bottles.

    I actually use the spray on my face. I have naturally oily skin and all the issues that come with trying to maintain even tone. I have used hormones, antibiotics (oral and topical), and every kind of retinoid you can imagine. Well, I continue to wash my face, because I can’t seem to stop doing that after all these years, but I pump 1-2 sprays after each face washing. I have noticed a very improved difference in my skin. It feels different. It’s not as oily, doesn’t have the ruddiness and it’s softened now. I wish I had found AO Mist 20 years ago.

    I have been using this for a number of months now, mainly on my face and armpits. I no longer need to use any kind of face moisturizer (-I am 61-) and, more importantly, my BO is basically gone. I often wear the same stinky sport-wicking polyester shirt for days, sometimes even sleeping in it, and, with a spritz of the mist plus a touch of baking soda, there is no stink. ..NONE! My main complaint is the same as everyone else’s: price! (and a smaller complaint: the spritzing nozzle doesn’t aim consistently. )

But within a week after restarting, the “glow” was back and my skin feels and looks smoother. The new packaging is awesome — especially the new spray mechanism for the mist!

    I used to have to use prescription antiperspirant (Drysol) and could still get a strong whiff of underarm odor when removing my clothes after work in the operating room. Since using Mother Dirt for a month, I have to put my nose right against my pit to get detect even a tiny bit of odor and my skin is no longer tortured from the super-strong antiperspirant. I’m convinced, but flinch a bit at the expense. It’s not just as effective as antiperspirant, but actually MORE effective at preventing odor.

    I started using the AO+Mist about 6 weeks ago and have not used any other product on my face since starting the mist! I used to use a facewash then moisturizer and makeup or tinted moisturizer.. My skin has never looked or felt more clear and healthy! I am thrilled with the results! Impressive!

    I have historically had “difficult” skin. Dry, dehydrated, sensitive, red…just awful! I have had to be very careful when trying new products, but I’ve tried them all… I was hesitant to try the AO Mist, because I couldn’t wrap my head around the fact that I wouldn’t use moisturizers and serums. But I tried it. And boy am I glad I did~! After only 5 days, I saw an immediate improvement to the problem patches (textural issues and clogging), skin appears less red with smaller pore size, appears hydrated and feels quite soft actually. I am amazed that after only 5 days there has been such an impact! My skin hasn’t felt this good or looked this good in YEARS!! Who knew that all the products I have been using over the years were hurting, not helping???

    I’m enjoying the products very much as well as the concept/theory behind them. As a doctor, I’ve been been speaking about the demise of our overall health due to our modern day lifestyles for years. To experience health to a greater degree we need to adopt some of the ways of our ancestors. Increasing probiotic bacteria to the environment on our skin is a fabulous idea……….wish I thought of it! Some positive effects I’ve noticed, a decrease in less desirable body odor, smoother/softer skin and a lessening of some of the visual signs of sun damage. I really enjoy using these producst and I am currently recommending them to my patients.

    If not for the exorbitant price of the AO+ Mist I would give this product five stars. I have had chronic dry skin during the winter months as well as absolutely rotten under arm odor. I decided to stop using soap while I was testing this product and simply exfoliate with water and a wash cloth. As a result, I have no dry skin except on my hands where I still wash with soap and my raunchy under arm odor was eliminated while the AO+ Mist was still active. Even after it died, the odor is significantly improved. This product is the only thing that stands a chance against my under arm odor. It was amazing. If I could afford it, I would always have a live supply of it on hand.

    I would call myself ‘the choir’ when it comes to being a target audience for this product. I stopped using most standard beauty products almost 7 years ago and only use, shall we say, spot treatment of soap. I don’t shower every day and wash my hair using the no-poo method maybe twice a month. I do all this because my skin and hair all look vastly better living life this way. You would never guess by looking at me I am living off-the-grid of beauty products. I was very interested to give the AO-Mist a try since all the reviews are glowing.

    Honestly, I didn’t see much of a difference at all. In fact, I’d dare say my minimal BO was slightly more pronounced, and strangely different, using it (I usually just use a light dusting of baking soda, if I remember.) I wonder if many of the 5-stars here are actually people undergoing the realization that we, as humans, really shouldn’t be showering every day with products full of chemicals which strip our natural oils and disrupt our bio-equilibrium.

    I guess I’m happy I have not become addicted to the Mist, because figuring out a $600/year price tag if I kept up with it was not something I could commit to. It looks like the packaging has been updated too, but when I ordered the sprays the overpackaging was really rather disheartening.

    Love the idea and that it is getting people thinking, but surprisingly just not for me.

    Just a curious medical student experimenting with different aspects of the microbiome. The concept seemed fascinating and the science promising, so I dove right in and got the whole package! The spray seemed to do as promised, for the most part. Sprayed it on consistently where I felt the need, after showers, after hand washing, before bed. I had some mild patches on my face, scalp, and arms and it started to clear up a few days after starting it, without the help of lotions or steroids. I did see some dry patches start to form on my forehead, but I could probably attribute that to the desert climate where I live. When I was sweaty and expecting to really stink, I was pleasantly surprised to smell that I wasn’t. I used it up in about 4 1/2 weeks. I’d say it was a successful experiment! The only downside is, as others have mentioned and you’ve probably seen, the price. A poor med student like me can’t afford this every month. Otherwise, I’m curious to see what further research will turn out with the AOBs!

    I give the product 4 stars. I bought the bundle kit and my experience after 1 month was great but not exceptional or awe inspiring.

    *easy to use (very simple and easy to adapt to existing routine).
    *no deodorant use ( I smelled fine the whole day, no weird sour smell after gym and really felt nice to not have to rub the cancer stick under the old arms)
    *Mist does not leave oily residue or anything, feels very refreshing on skin.

    *Price. I mean I am fortunate to afford such a product but I don’t see the average middle class generation spending this kind of money on this product. For me, I will not spend $49.99 a month on a product that only last 1 month!. Maybe, if this product was covered by my insurance company for medical reasons or if the company can get costs lower to compete with other alternative washing regime products, then maybe Id splurge a bit and spend say $15.00 a month, but $50? That’s not gonna happen.

    All in all, it was a cool experience and I was glad I could try out this new product and give feedback.

    This is a good product. It works, it’s a great idea. I’m giving it three stars because it’s overpriced and over-packaged. It’s a very small bottle of spray after all of the excessive packaging comes off. I really want this product to do well so I’m suggesting that you lower the price and reduce the amount of waste created in packaging. It’s ironic that the cardboard box the spray comes in is decorated with trees when trees have to die for that packaging and I think that much of your target clientele will agree with me.

    Like many other reviewers, I read about the product in Bloomberg magazine. I was very captivated and interested in replacing the many, and I mean many products that I use on my face, body and hair. I am middle age, very active and live in Florida (lots of sweat and heat). Here are my results after only one week: My facial skin is perfectly balanced, no oily spots and no dry areas. I conducted a science experiment on myself by playing tennis, running, walking dogs and only showering with water and using Mother Dirt and its shampoo for my hair. I was amazed that I had no body odor and my hair was bouncy and happy! I also learned that I could spritz between sports if I felt that i was overworking these “little miracles” in the bottle.

    In short, I am a customer for life.

    P.S. Ladies, do not deprive your hair and scalp of a spritz or two. You will love the results.

    I decided to use the Mother Dirt Spray specifically to reduce or eliminate the strong body odor from playing sports and exercising. I spayed the mist on before exercising and found the strong ammonia smell completely disappeared. I now use the mist every time before exercising.

    Body odor went away! The house smells better, and I’m less worried about BO in public. It was hard to not use strong soaps and anti perspirant at first because I was afraid I’d smell bad. Then it occurred to me to use more mist if I started to notice an odor. I was so excited when that worked!
    I keep the bottle in the fridge to preserve every precious drop, but that does make it easy to forget. I absolutely love Mother Dirt, and never want to be without it. –customer for life

    Mindblown. I have strong BO because I love physical activity, plus I sweat a lot so I use deodorant often, which gives me itches and uncomfortable sensations. I was very much sold on the idea of this product because I believe in good microbes and when I received my bottle, I used it before jogging, then after my shower. No deodorant at all. I have to say, my armpits didn’t smell until next morning, which to me, is pretty much incredible!

    I’ve been using the mist for 2 weeks now after hearing about Mother Dirt on my local news and then further reading about the history on the Bloomberg article. This fits with my nature knows best attitude with gardening. I already limited showers so this fits right in with my regime. I used up my first bottle in 1 week, it’s hot here so sweat was often. I went cold turkey and cut anti antiperspirant. Worked fine for a few days, but after a work out the BO returned. However, the rest of my body responded amazingly well. I used to have cracked & dry hands & feet. I also had dry body skin & scalp. Now my skin is soft, all the cracks, itching, flakes & callus have healed. Amazing. Lotion never did this. And for the scalp was constantly using Head & shoulders. So I am hooked. Hopefully the under arms will respond some day. Still worth switching for the other results.

    I am so pleased with the AO Biome Mist. It feels great on my skin. I’ve primarily used it on my face for over 8 months. I have had a life-long issue with oily skin and now as I age, dry skin is also a challenge. I feel the mist balances my skin for just the right amount of moisture. The pores do not look as large and overall redness is much reduced. I highly recommend this product. I also love the idea of helping the ‘good bacteria’ so that they can do their job to support my skin health ! I hope Mother Dirt develops other products that are biome friendly. I’d especially like to purchase sunscreen that compliments the microbiome, along with make-up. Go Microbes !

    As someone who has struggled with my skin for my entire adult life, I really have nothing but praise for the AO+ Mist. I’ve been using it for almost a year and I can’t remember the last time my skin looked and felt so good. One of the best things about it is how easy it is to use. Just spray where needed and your done. I tried many other products where a whole routine needed to be maintained, day and night, to see any results, assuming you ever saw any! If your story sounds like mine, give this product a shot. It’s worth it.

    I first read about Mother Dirt products in Bloomberg Magazine. I ordered all three; the mist, shampoo and cleanser and have been using all three for about a month. I used to shampoo daily which left my hair striped of its natural oils. Now I shampoo every other day with fantastic results. My hair is soft and shiney. The cleanser and mister are used after I shower and my skin also feels much smoother and softer. These are great products!

    My friend John Durant turned us onto the AO+Mist product months ago and in the weeks we have gone without it (since we ran out) I have noticed differences in how my skin feels and looks, for the worse. Our family only uses personal care products that we could eat (in terms of composition) so we are happy to have such a natural addition to our personal care routine.

    I have been using the mist ever since the New York Times ran an article about it. It is the finest overall product the I have ever used for my complexion. And, over the years, I had tried just about everything. AO + Mist makes my complexion look and feel good.

    More recently, I started using the Mother Dirt body cleanser and shampoo. They both are great complements to the mist. Now, I cleanse both my hair and body followed up with the mist. The results are fantastic. My skin never looked so good!

    Love this! I used the beta product, and really didn’t know what I would do if it never became a real thing I could continue to buy. I’ve used it in very hot weather with great results. Unlike deodorant, it doesn’t wear off till you wash it off. I grew up in the “only good germ is a dead germ” era, and it’s a great relief to not be at war anymore 🙂

    I read about AO Biome in Bloomberg Businessweek and was immediately intrigued! I have used every facial cleanser, from the all-natural to heavy duty cleansers, and found no help in the appearance of my skin. I have been using the misting spray on my face for over two weeks and noticed a clear difference in the health of my skin. My skin is much less red and dry and I barely use lotion (besides sunscreen). It’s amazing going from using a three step daily routine of harsh products to a simple spritz. I am extremely grateful I found this amazing product!

    I’ve been using this product about 9 months and I’m happy with the results. I no longer use soap or deodorant on my face or body (I do use soap to cleanse my hands of any pathogens). My dry skin is moister than before and I no longer use lotion or skin creams. Previously I had difficulty with the skin on my perineum getting dry and raw from soap, and now that is not an issue, the skin has healed. The philosophy of restoring a more natural ecology to the skin biome makes sense to me, and AOBiome has done a good job of telling that story. Thank you, AOBiome.

    I have been using this product for about 3 months. I was a bit skeptical at first. The difference is very subtle, but I have not used soap or shampoo since and my skin is healthier than ever! I truly believe that culturing a symbiotic relationship on the largest organ of our body (our skin) will truly redefine how we think about our place on this planet.

    It’s about time we wake up to the fact that we’ve been fighting the good guys all along. So many unknown chemicals in skin care products these days which just kill and remove everything on our skin in an effort to keep us clean. I’ve been a loyal AO+ Mist user since the beginning and I swear by it as a deodorizer and skin health restorer. Commit to it for a week and you’ll see the results. The deodorizing effects are instant and the life it gives back to your skin you’ll begin to see after only a couple of days! Excited to see the many health benefits that come of restoring our natural skin and body biome. Great job AO for ushering a change of mentality.

    I have been using AO Biome for 5 weeks now and have noticed a big difference in the look and feel of my skin, particularly on my face. I am in my mid-50s and for the past year, had been experiencing extremely dry skin on my face. There wasn’t a moisturizer I could find that would combat the dryness without clogging my pores. Since using AO Biome, I no longer use any product other than water on my face (no soap, moisturizers, wrinkle cream, anti-aging products, etc). My face is no longer dry and scaly. My large pores seem to be smaller and my skin is softer! I spritz AO Biome on my entire body in the morning after waking, and then in the evening before bed. Since doing this, I’ve been able to reduce my showers to one every other day. This is truly amazing because, living in the hot, humid weather of Florida summers, I used to shower up to 3x a day! Here’s an example: I had not showered for 2 days, and went to a friend’s house to help her put up a bird feeder. I was standing “downwind” of her and out of the blue she commented, “You smell so GOOD!” I am so pleased with AO Biome and would recommend the product to anyone.

    Like many other people, I heard about AO+ on NPR and saw the subsequent NYTimes article. I have always thought we are using way to many unnatural chemicals in our everyday lives from cooking ingredients to cleaning products. I never had any skin problems aside from minor acne, but it is refreshing to use bacteria to fight skin odor issues. Without soap and shampoo, my skin is softer and my hair is stronger. You won’t be disappointed with the results.

    I have been using the mist for about a year and have found it to do a much better job than soap or deodorant which I used to use for washing up underarms, feet and private areas. I have very dry skin and do not want to shower or bathe too often. The mist lets me accomplish that by keeping me clean and sweet smelling for many days. I use the mist once a day and feel very clean with that frequency. During very hot days I might need to mist my under arms an additional time but that has always been enough to take care of the extra sweat. I love this product and can’t think of going back to my old soap and deodorant days. I also have been using the cleanser and shampoo and am also thrilled with them. Thank you AO Biome for developing these wonderful products.

    I was SO excited to finally order this. I’ve spent years&years with acne, eczema, itchy dry skin and really bad pit BO (for a lady it’s pretty gross and I use men’s deodorant) I found that soap and acne products make things so much worse so switching to natural products has really helped-but now I need something to repair the damage. After just a few days my skin feels so soft, smells better and I went deodorant free yesterday. Which is a big deal for me especially at work. At first the smell was gross but when I climbed into bed at the end of the day I was amazed that my pits smelled…good. I honestly didn’t expect it to tackle that issue so well. I look forward to my new “colony” of helpful friends!
