Just like our gut needs good bacteria to be healthy, the same is true for our skin.

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