A skincare-active primer that strengthens the skin's barrier to lock in moisture for a healthy-looking, glowing finish. This silicone-free primer visibly improves bare skin in just 1 week. The primer instantly smoothes and brightens for better makeup application, finish and wear. In just one week, bare skin is visibly more even-toned, hydrated and smooth. It is powered by fermented kefir and niacinamide, two prebiotics that fuel the ability to maintain a healthy microbiome.
