Sun allergy is an allergic reaction of the skin upon exposure to sunlight. It does not develop long-term complications in most people, but in some people, it may last longer than others depending on their skin type.

Spending time in the sun, especially after winter is usually a pleasurable experience, but for people, who have sun allergy, even a few moments in the sun can become a painful experience. Read to know the prognosis of sun allergy.

  • In most people, sun allergy symptoms improve once the affected areas are protected from sunlight. The symptoms are usually mild in most people and only a few people develop severe sun allergy. The symptoms tend to disappear on their own in a couple of days in most people, though for some, it keeps re-occurring every spring and summer (but with a decrease in the skin's sensitivity to sunlight).
  • Sun allergy symptoms may improve without treatment in a couple of days or with the use of over-the-counter medications. For severe or hardened allergy, medications, such as an oral antihistamine like diphenhydramine or chlorpheniramine or any anti-rash skin cream containing cortisone may be needed.
  • Very few people develop severe allergy symptoms for which specialised treatment, such as ultraviolet phototherapy, psoralen and ultraviolet light, antimalarial drugs or beta-carotene tablets may be needed.
  • Most people do not develop any long-term complications. In most people, the sun allergy lesions heal without scarring. Only rarely do some people with severe actinic prurigo develop pitted scars.
