When are topical corticosteroids recommended for pityriasis alba?

Pityriasis alba commonly appears as pale, slightly scaly patches, often on a child’s face, after mild eczema-like inflammation. The colour difference can look stronger after tanning because surrounding skin darkens. A corticosteroid addresses active irritation and scale, not the lighter colour itself. Other causes of pale patches can resemble it, so a changing, sharply defined or completely smooth patch deserves assessment rather than automatic treatment.

Use a gentle cleanser, apply a fragrance-free moisturiser regularly and protect exposed skin from sun so the colour contrast is less noticeable. If a clinician prescribes a topical corticosteroid, follow the directions and keep it away from the eyes unless specifically told otherwise. Avoid bleaching products, scrubbing and unprescribed combination creams. Information about these medicines is available at [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/).

Arrange an examination if patches spread quickly, become painful, lose sensation, develop blisters or involve the scalp and nails. Review is also sensible when the diagnosis is uncertain or the skin remains inflamed despite gentle care.

Ask whether the pale areas fit pityriasis alba, whether treatment is needed for active inflammation, how to apply it near the face, and how long colour recovery may take.
