What is actinic prurigo?
Actinic prurigo is an itchy skin condition that arises with sunlight exposure. Small and extremely itchy pimples (papules) appear on the areas exposed to the sun usually without a few days after intense sunlight exposure. Sunlight is the trigger but not the cause of the disease. The exact cause of this hypersensitivity to sunlight is unknown. Genetic factors that lead to abnormal immune activity seems the most likely contributing factor to actinic prurigo. The condition not only affects the skin as a significant number of sufferers experience lip and eye symptoms as well.
