Mechanism of Action

Produces desquamation of hyperkeratotic epithelium via dissolution of the intercellular cement which causes the cornified tissue to swell, soften, macerate, and desquamate. Salicylic acid is keratolytic at concentrations of 3% to 6%; it becomes destructive to tissue at concentrations >6%. Concentrations of 6% to 60% are used to remove corns and warts and in the treatment of psoriasis and other hyperkeratotic disorders.
