Treatment of Pityriasis Alba

First-Line Treatment Options

The British Journal of Dermatology recommends topical corticosteroids, with low to moderate potency topical steroids applied to lesional skin twice daily for 2-4 weeks, as effective for reducing inflammation and scaling 1
The American Academy of Dermatology suggests regular application of alcohol-free moisturizers containing 5-10% urea at least twice daily helps restore skin barrier function, as supported by the Annals of Oncology 2, 3
The Skin Cancer Foundation advises use of sunscreen (SPF 15 or higher) on exposed areas is essential to prevent worsening of hypopigmentation, as recommended by the Annals of Oncology 3

For mild cases, the American Academy of Dermatology recommends starting with regular moisturizers and sun protection, and adding low-potency topical corticosteroids if no improvement after 2 weeks, as supported by the British Journal of Dermatology and the Annals of Oncology 1, 3
For moderate cases, the British Journal of Dermatology suggests low to moderate potency topical corticosteroids twice daily for 2-4 weeks, concurrent use of moisturizers and sunscreen, as supported by the Annals of Oncology 1, 2, 3

The British Journal of Dermatology recommends an initial treatment course typically lasts 2-4 weeks for corticosteroids 1
The American Academy of Dermatology advises moisturizers and sun protection should be continued indefinitely to prevent recurrence, as supported by the Annals of Oncology 3

The American Academy of Dermatology advises against using alcohol-containing preparations, as they worsen the xerotic skin characteristic of pityriasis alba, and also recommends avoiding aggressive anti-acne treatments, as pityriasis alba is not seborrheic 4
