This 97% oil-free formula focuses on balancing the skin's microbiome (the ecosystem of bacteria on the skin, which when out of whack can lead to skin imbalances like acne). It includes a host of prebiotics to encourage a healthy microbiome, alongside niacinamide to regulate sebum and fade post-blemish pigmentation, and beta glucan to soothe inflammation. It comes with a glycolic acid activator which can be used as a treatment a few times per week to deep clean the skin to reduce breakouts.
