From the Research
For treating pityriasis alba, I recommend starting with a mild topical corticosteroid such as 1% hydrocortisone cream applied twice daily for 1-2 weeks to reduce inflammation, as supported by the study 1 which showed the efficacy of pimecrolimus cream 1% in treating pityriasis alba. This approach should be combined with a gentle, fragrance-free moisturizer applied liberally at least twice daily, even after the corticosteroid course is completed.
- Key considerations in treating pityriasis alba include:
- Reducing inflammation with topical corticosteroids
- Maintaining skin hydration with emollients
- Protecting the skin from sun exposure to prevent worsening of hypopigmentation
- For persistent cases, consider tacrolimus 0.03% or pimecrolimus 1% cream applied twice daily for 2-4 weeks as steroid-sparing alternatives, as suggested by the study 1.
- Emollients containing ceramides or petrolatum (like CeraVe, Eucerin, or Vaseline) are particularly effective for maintaining skin hydration, and sun protection is essential - use a broad-spectrum sunscreen with SPF 30+ daily on affected areas. Pityriasis alba is a common, benign condition characterized by hypopigmented patches typically on the face, and is often associated with atopic dermatitis, as noted in the study 2.
- The treatment focuses on addressing the underlying inflammation and dryness that contribute to the pigmentation changes, with the goal of improving morbidity, mortality, and quality of life outcomes. Most cases improve with consistent treatment, though complete resolution may take several months as melanocytes gradually recover their function, as indicated by the study 3.
