What is Duofilm® (salicylic acid) used for?
Duofilm® is commonly used to treat skin or foot with warts, corns, and calluses. This product should not be used on the face or on moles, birthmarks, warts with hair growing from them, or genital/anal warts.
Salicylic acid is a keratolytic. It belongs to the 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.
