You’ll never have to shower again if you use this probiotic spray. Seriously.

A Bug's Life

Getting ourselves clean, we thought, involved scrubbing every fleck of dirt, germ, bacteria, and temporary tattoos from our skin.

But the Cambridge-based beauty startup Mother Dirt is taking a radical new approach.

The idea is that our decades of bacteria-killing bloodlust have also decimated the microorganisms on our skin that consume irritants and toxins in sweat.

Their AO+ Mist contains live Ammonia Oxidizing Bacteria that promise to “restore balance to skin microbiome” that’s been removed by modern hygiene and lifestyles.

And the man who developed it all, chemist David Whitlock, claims he hasn’t showered or bathed in 12 years, without a single complaint about his B.O.

But skipping the shower is not a requirement for using Mother Dirt’s products.

“That’s what I do,” Whitlock said, “but in order to enjoy the benefits of ammonia-oxidizing bacteria, you don’t have to stop showering. You just have to use the spray after drying off after a shower to restore balance to your skin flora.”

The product went viral in May, 2014, when The New York Times’ Julia Scott reported seemingly miraculous results.

Since then, it’s picked up glowing reviews everywhere from Vogue to Bloomberg Businessweek.

A bottle of AO+ Mist runs $49 – you can order it here. Their Biome-Friendly Moisturizer ($34) encourages the activity of the Ammonia Oxidizing Bacteria (that’s supposed to be a good thing). And Mother Dirt also offers a shampoo ($15) and face and body cleanser ($15).
