Salicylic acid is a keratolytic which belongs to the same class of drugs as aspirin. In medication, it is used on the skin to treat skin and foot warts and help remove corns and calluses. Salicylic acid works by increasing the amount of moisture on skin and dissolving the substance that causes skin cells to stick together, which makes shedding skin cells easier. In skin treatment products, salicylic acid is a naturally occuring and synthetically produced beta hydroxy acid.
