Salicylic acid is used on the skin/scalp to treat psoriasis and other dry, scaly skin conditions. It belongs to the same class of drugs as aspirin (salicylates). This medication should not be used by children younger than 2 years.Salicylic acid causes the skin to shed dead cells from its top layer by increasing the amount of moisture in the skin and dissolving the substance that makes the cells clump together. This effect makes it easier to shed the skin cells, softens the top layer of skin, and decreases scaling and dryness.
