Characterized by fine, scaly, round or oval patches of skin, pityriasis alba is a fairly common condition that occurs mostly in children between the ages of 6 and 16 and is self-limiting. The scaly patches, which are at first reddish, usually resolve with the affected areas becoming transiently hypo-pigmented (i.e., of a lighter coloration than they previously were). These hypopigmentations usually take some time before they go away and the skin returns to its normal color. Pityriasis alba most frequently manifests on the face and neck and as well as the upper arms and upper torso.
