Watnil Lotion is combination of Salicylic acid and Lactic acid. Salicylic acid helps cause the wart to gradually peel off. It also help to remove corns and calluses. It should not be used on the face or on moles, birthmarks, warts with hair growing from them, or genital or anal warts. Salicylic acid is a keratolytic. 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. Lactic acid increases moisture in the skin by softening/dissolving keratin holding the top layer of skin cells together. This helps the dead skin cells fall off and helps the skin keep more water in.
