Keratolytic (/ˌkɛrətoʊˈlɪtɪk/[1][2]) therapy is a type of medical treatment to remove warts, calluses and other lesions in which the epidermis produces excess skin.
In this therapy, acidic topical medicines, such as Whitfield's ointment or Jessner's solution, are applied to the lesion in order to thin the skin on and around it.
This therapy causes the outer layer of the skin to loosen and shed.
[4] While cytostatic agents such as zinc pyrithione are first line, keratolytics (salicylic acid and sulfur) can also be used in the treatment of dandruff and seborrheic dermatitis.
[5][6] Sulfur and salicylic acid can also be used to effectively treat acne and cradle cap in some patients.
