MotherDirt AO+ Mist - Does It Work?-Review

What is MotherDirt AO + Mist?

There is no question that living with someone close to you who has body odor is not ideal and not something that is ever welcomed for a loved one.  But unfortunately, it is not uncommon for this to occur, and the person who is suffering from the malodors does not always know that this is actually a problem. Today we are reviewing MotherDirt AO + Mist, a live probiotic spray for the skin that contains Ammonia-Oxidizing Bacteria or AOBs that is designed to relieve sweating, improve skin clarity by converting ammonia into beneficial byproducts which can help calm the skin and keep other microorganisms in check while reducing your dependence on products like deodorants, moisturizers, and makeup.

Ingredients & How It Works

The ingredients are Aqua (water), Nitrosomonas Eutropha (live cultured Ammonia-Oxidizing Bacteria (AOB), Disodium Phosphate (inorganic salts used to buffer the AOB), and Magnesium Chloride (natural salts).

The ingredients work by converting ammonia into beneficial byproducts. It is believed that modern hygiene wipes out the beneficial bacteria from your skin. By consuming the ammonia on our skin, AOBs help keep a healthy pH level and the byproducts help calm the skin and keep other microorganisms in check.

Daily Serving

The instructions from MotherDirt state to shake the bottle well and then to choose the areas where you sweat the most to spray the product there once or more a day. It is best to store this product in the refrigerator because it contains live AOBs.  The product is safe to use for children and babies.

The Cost

The product is available both on the manufacturer’s website and third-party sites.  On the manufacturer’s website, a 3.4 fl oz. bottle of AO + Mist is available for $49.90 without bulk purchasing options. Third party websites sell the product for $49.95 for one bottle; $94.90 for two bottles, and $133.95 for 3 bottles.


MotherDirt specifies that if the product does not work, they will issue a refund within the first six months after purchase.

Our Review Summary of MotherDirt AO+ Mist

MotherDirt AO+ Mist is an original product that works to tackle the problems of body odor by restoring good bacteria that they claim the skin needs in order to be in an optimal condition. Unfortunately, the product is expensive and comes with mixed reviews.  In terms of the expense, the spray bottle does not last quite long enough to justify the price and because consumers share not wanting to use a lot of it so that it would last more than a week or two. And many reviewers claim that this product simply did not work and was entirely ineffective. Although it seems like a nice idea to have a spray that maintains a skin balance fighting bad odors, one would need to consider the number of negative consumer reviews and its expensive price, and then decide whether it's worth trying.  Our guess is that consumers would sooner try other leading products that are less expensive and well reputed.
