Salicylic Acid is a colorless to white, crystalline organic acid used chiefly in dermatology and chemistry. It’s best known as a keratolytic agent in acne treatments and as a reagent in organic synthesis. In consumer products it appears as acetylsalicylic acid’s precursor and in various salicylate salts. The term combines the chemist’s salicyl- root with -ic acid, indicating an acidic carboxyl group.
