Why "Dirty" Is Better
Just like your gut, your skin relies on a microbiome of beneficial bacteria to stay healthy. Some of the most important of these are called ammonia-oxidizing bacteria (AOB). These microscopic bugs consume the ammonia on skin, which, in higher levels, can cause things like acne and body odor. Unfortunately, modern antibiotics and soaps have wiped out AOB on most of us. "We've altered the natural bacterial environment our skin had back in the hunter-gatherer days," says Dr. Larry Weiss, chief medical officer for AOBiome. He believes that we can improve skin health (and in many cases body odor) by rebuilding those beneficial bacteria colonies. One way to do it: Mother Dirt AO+ Mist ($49), a face and body spray developed by Weiss and AOBiome that contains live probiotics and AOB.
