Salicylic acid is a keratolytic. It belongs to the same class of drugs as aspirin (salicylates). It works by increasing the amount of moisture in the skin and dissolving the substance that causes the skin cells to stick together. This makes it easier to shed the skin cells. Warts are caused by a virus. Salicylic acid does not affect the virus.
