Photodermatitis, sometimes referred to as "sun poisoning" or photoallergy is a form of allergic contact dermatitis in which the allergen must be activated by light to sensitize the allergic response, and to cause a rash or other systemic effects on subsequent exposure. The second and subsequent exposures produce photoallergic skin conditions which are often eczematous.



Many medications and conditions can cause sun sensitivity, including:

Photodermatitis can also be caused by plants. This is called phytophotodermatitis.


May result in swelling, a burning sensation, a red itchy rash sometimes resembling small blisters, and peeling of the skin. Nausea may also occur. There may also be blotches of large to small areas where the itching may persist for long periods of time. In these areas an unsightly orange to brown tint may form, usually near or on the face.


Prevention includes avoiding exposure to the sun and wearing sun block on the affected area.

  • Cover up: wear long sleeves, slacks, and a wide-brimmed hat whenever harsh exposure is probable
  • Avoid chemicals that may trigger a reaction
  • Wear sunscreen[1][2] at least factor 30 with a high UVA protection level
  • Wear gloves and/or remain indoors after handling fruits or plants which increase sensitivity to light
