The AHA mix is a blend of lactic acid, glycolic acid, and fruit acids from bilberry, blueberry, super maple, orange, and lemon. These help to exfoliate away dead and dull skin, to reveal fresher, smoother skin below with refined tone and texture. The BHA is salicylic acid, which helps to get deep into pores to ease congestion and help prevent breakouts, leaving skin appearing smoother and more radiant.
