Salicylic acid is one of the most effective ingredients in combating certain types of acne. It is a beta hydroxy acid that functions as a keratolitic exfoliant, meaning it can soften the keratin (proteins) on the surface, and shed dead skin cells. It is also antiseptic. Natural salicylic acid is derived from the bark of the white willow tree, processed, then formulated into a myriad of skin care products designed to rid the skin of built up proteins. This beta hydroxy acid works by expiditing the speed at which skin cells turn over, then getting into the pores and neutralizing the bacteria inside.
