Pityriasis alba is a common, harmless skin condition seen mainly in children and adolescents. It presents as dry, pale, slightly scaly patches usually seen on the face, especially the cheeks. The condition is often more noticeable in darker skin tones and after sun exposure.
The exact cause of pityriasis alba is not fully understood, but it is believed to be related to mild eczema, dry skin, and skin inflammation. Excessive sun exposure may make the surrounding skin tan, causing the pale patches to appear more prominent.
The lesions are usually round or oval with ill-defined borders and mild scaling. Most children do not experience itching or discomfort. Parents often become concerned because the patches resemble fungal infections or vitiligo.
Diagnosis is usually clinical and based on characteristic appearance. Unlike fungal infections, pityriasis alba does not spread and does not show complete pigment loss like vitiligo. Treatment mainly focuses on skin hydration and reducing dryness. Regular use of moisturizers, gentle cleansers, and sunscreen can help improve the appearance. Mild topical steroid creams may sometimes be prescribed for inflamed patches.
The condition is benign and usually resolves gradually over months to years without scarring. Reassurance and proper skincare are important parts of management.
If your child has persistent white patches on the face or body, consult DermcareMD Skin and Hair Clinic by Dr Neha Athalye for proper evaluation and expert pediatric dermatology care.
