Pityriasis Alba

Pityriasis alba is a condition that causes light areas, often with minimal scaling. These most commonly occur on the face of children or adolescents who have a history of dry skin or eczema.

Pityriasis alba may be more noticeable with sun exposure, which makes the surrounding darker areas more prominent. It tends to improve with the treatment of underlying dry skin and eczema.

Frequently Asked Questions

How do dermatologists diagnose pityriasis alba?

Dermatologists are typically able to make the diagnosis of pityriasis alba by examining the skin. In rare cases where the diagnosis is not clear, additional tests such as taking a small sample of skin (also known as a skin biopsy) may be needed to rule out rarer conditions that can cause light spots.
