Guide To The Conditions That Cause Hypopigmentation

Pityriasis Alba

Pityriasis alba typically affects children and young adults, and it is commonly associated with eczema. Patients with pityriasis alba develop pink or red oval rashes, which are generally dry and scaly in texture. The patches occur most often on the back, face, upper arms, and chest, and they normally resolve with the application of moisturizers. After the rash fades, patients might observe hypopigmented spots in these areas. Medical treatment is not normally required, but dermatologists may choose to prescribe heavy moisturizers, topical steroid creams, or pimecrolimus to reduce skin discoloration, itchiness, and dryness. Pityriasis alba frequently resolves once a patient reaches adulthood; however, some patients may experience repeated episodes.
