Mother Dirt AO+ Mist live probiotic spray for the skin.

The world's first live probiotic skincare. When used twice a day, the patented Ammonia-Oxidizing Bacteria (AOB) restores balance to your microbiome, leaving you with naturally radiant skin.

Formulated with a patented, live "peacekeeper" bacteria to restore essential bacteria that's been removed by modern hygiene and lifestyles. We store AO+ Mist in a specially purchased refrigerator to keep the beneficial bacteria alive. They can survive up to one week in transit. Upon receipt, store the bottle in your refrigerator.

OUR SKIN IS STRUGGLING As we've gotten "cleaner", we're having more problems with our skin. SKIN NEEDS GOOD BACTERIA Just like our gut needs good bacteria to be healthy, the same is true for our skin.

   

  OUR CRITERIA & PATENT-PENDING PROCESS:
  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.
  
  WHY WE'RE PRESERVATIVE- FREE:
  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.
  
  INGREDIENT SELECTION:
  
  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.
  
  EXPIRATION DATES:
  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.
  
  PACKAGING & MANUFACTURING:
  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.

  PRESERVATIVE-FREE

  We don't use preservatives in any of our formulas, and we source pure, unpreserved raw ingredients. Why? 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
• HOW AOBS WORK
  
  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.
  
  AOBS ON THE SKIN
  
  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.
  
  CLINICAL RESEARCH
  
  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.
• DO I NEED TO REFRIGERATE IT?
  We store the AO+ mist in a refrigerator in our warehouse. It can survive outside of a fridge for a few days, which is why we can ship it to you. Select Express Post if you're outside of Sydney. 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.   Temperature extremes experienced during shipping will not cause harm to your Mist. We’ve done extensive temperature and shipping testing to make sure the AOB in your Mist are in good condition when they arrive.
  
  Lastly, it’s important to remember while the AOB in the Mist do have temperature sensitivity, they are not as sensitive as you might think. They are happy and active across a large range of temperatures: between 0 degrees and 49 degrees centigrade. Below are some more specifics in case you’re curious!
  
  The Mist can withstand 72 hours at 38 degrees centigrade. It would require hours at well-over 43 degrees to degrade the AOB.
  
  The Mist and cold
  Freezing temperatures are always bad! The coolest it should get is 0 degrees centigrade.
  
  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.
