If your sensitive skin needs a gentle guardian, then let lactic acid lend a comforting hand. While exfoliation helps to brighten your skin, most exfoliators can feel irritating on sensitive skin. But a gentle exfoliator like lactic acid helps to delicately buff away dead skin cells and impurities to leave your skin feeling radiant and hydrated. So, let lactic acid be your sensitive skin’s true confidant in a time of need.
