Lactic Acid

Lactic acid is the gentlest of the strong AHAs  a larger molecule than glycolic, so it works more slowly and on the surface, with a key bonus: it's also hydrating, drawing water into the skin as it exfoliates. That makes it ideal for dry and sensitive skin that can't tolerate harsher acids. It smooths and brightens without the sting. Use a few nights weekly. Suits Dry Skin and Sensitive Skin.
