Regular exfoliation is key to achieving healthy skin and this award winning formula does that and more. A clinically proven blend of glycolic, salicylic and lactic acids works together to effectively exfoliate the skin while limiting the chance of irritation. Why three acids? Because each acid serves a different purpose. Glycolic acid helps counteract the visible signs of aging. Lactic acid helps improve moisture content and brightness, while salicylic acid works on the surface to cosmetically help keep skin in the clear.
