Medical Care

Pityriasis alba resolves spontaneously and may not require treatment. Treatment may include a simple emollient cream. For chronic lesions on the trunk, a mild tar paste may be helpful.

Topical 1% hydrocortisone preparations may be helpful if mild inflammation is present.[16] Topical 0.1% tacrolimus ointment may be indicated only after other treatment options have failed.[7] Pimecrolimus 0.1% cream has been reported to be effective.[17]
