Pityriasis alba

Pityriasis alba is a benign skin condition, common in children and adolescents, characterised by the appearance of pale, slightly scaly patches, often on the face, arms, or trunk. Although harmless, it can sometimes be a cause for concern. Fortunately, pityriasis alba usually resolves spontaneously around puberty.
