In the last 100 years indoor lifestyles and personal care products removed the peacekeeping Ammonia-Oxidizing Bacteria (AOB) that lived on our skin.
While on the skin, AOB continuously keeps the skin’s ecosystem in check. Our AO+Mist contains a live culture of AOB that’s been clinically proven to restore clarity & balance to your skin in 4 weeks.
Our biome-friendly products strike a balance with science and nature, allowing AOB to thrive in the modern world. Unpreserved, plant-based products nurture AOB and maintain harmony in the skin biome, while traditional products with harsh chemicals kill it.
All products are Hypoallergenic, Non-irritating, Clinically-tested, Allergy-tested and Dermatologist-reviewed.
