Medicine for pityriasis alba

Pityriasis alba commonly causes pale, slightly dry patches, often on the face of children or young people. The surface may have fine scale, and the colour difference can look stronger after surrounding skin becomes tanned. It is not the same as a contagious infection.

A clinician may inspect the patches and ask about itch, scale, eczema and changes over time. Other causes of white patches can resemble it, so a new, spreading or unusual patch may need examination before treatment is started.

Apply a bland emollient regularly, especially after washing, and use gentle, fragrance-free cleansers. Sun protection helps reduce contrast between the patch and nearby skin. Avoid scrubbing, bleaching products and picking at scale.

If the area is inflamed or itchy, a clinician may prescribe a mild topical corticosteroid for a limited course or recommend another suitable option. Use it only on the advised areas and follow the instructions, particularly on the face and in children.

Arrange an assessment if patches are rapidly spreading, sharply white, painful, very itchy, thickly scaled or associated with hair or nail changes. Review is also useful when the diagnosis is uncertain or the skin does not settle with gentle care.

Seek advice if a prescribed cream causes marked burning, thinning, easy bruising or worsening redness. A clinician can distinguish irritation from the original condition and adjust the plan safely.

Ask: Does this look like pityriasis alba or another cause of white patches? Which moisturiser is suitable? Is a corticosteroid needed, and how should it be used on the face? What changes should prompt a review?
