"Refreshing Cosmetic Mist contains billions of cultivated Nitrosomonas eutropha, an ammonia-oxidizing bacteria (AOB) that is most commonly found in dirt and untreated water. AOBiome scientists hypothesize that it once lived happily on us too — before we started washing it away with soap and shampoo — acting as a built-in cleanser, deodorant, anti-inflammatory and immune booster by feeding on the ammonia in our sweat and converting it into nitrite and nitric oxide

While most microbiome studies have focused on the health implications of what’s found deep in the gut, companies like AOBiome are interested in how we can manipulate the hidden universe of organisms (bacteria, viruses and fungi) teeming throughout our glands, hair follicles and epidermis. They see long-term medical possibilities in the idea of adding skin bacteria instead of vanquishing them with antibacterials — the potential to change how we diagnose and treat serious skin ailments. But drug treatments require the approval of the Food and Drug Administration, an onerous and expensive process that can take upward of a decade. Instead, AOBiome’s founders introduced AO+ under the loosely regulated “cosmetics” umbrella as a way to release their skin tonic quickly. With luck, the sales revenue will help to finance their research into drug applications. “The cosmetic route is the quickest,” Jamas said. “The other route is the hardest, the most expensive and the most rewarding.”

The story of AOBiome begins in 2001, in a patch of dirt on the floor of a Boston-area horse stable, where Whitlock was collecting soil samples. A few months before, an equestrienne he was dating asked him to answer a question she had long been curious about: Why did her horse like to roll in the dirt? Whitlock didn’t know, but he saw an opportunity to impress.

Whitlock thought about how much horses sweat in the summer. He wondered whether the animals managed their sweat by engaging in dirt bathing. Could there be a kind of “good” bacteria in the dirt that fed off perspiration? He knew there was a class of bacteria that derive their energy from ammonia rather than from carbon and grew convinced that horses (and possibly other mammals that engage in dirt bathing) would be covered in them. “The only way that horses could evolve this behavior was if they had substantial evolutionary benefits from it,” he told me.

I asked AOBiome which of my products was the biggest threat to the “good” bacteria on my skin. The answer was equivocal: Sodium lauryl sulfate"
