From the Research

Hypopigmentation during the healing phase of pityriasis rosea is a normal occurrence that typically resolves on its own within several months, and no specific treatment is needed as color usually returns gradually over 2-6 months 1. This post-inflammatory hypopigmentation happens because the inflammation from pityriasis rosea temporarily disrupts melanin production in the affected skin areas. Some key points to consider in the management of hypopigmentation in pityriasis rosea include:

  • Protecting the hypopigmented areas from sun exposure by using broad-spectrum sunscreen (SPF 30+) and wearing protective clothing, as UV exposure can worsen or prolong the pigmentation differences 2.
  • Understanding that the hypopigmentation is more noticeable in individuals with darker skin tones.
  • Recognizing that this is part of the normal healing process and not a complication or scarring. If the hypopigmentation persists beyond 6-12 months, consultation with a dermatologist may be warranted to rule out other conditions or discuss cosmetic options like topical treatments that might help restore pigmentation more quickly 3. It's also important to note that pityriasis rosea is a self-limiting condition, and treatment is mainly focused on controlling symptoms, with options including corticosteroids, antihistamines, and ultraviolet phototherapy 4.
