Photosensitivity is an abnormal reaction of the skin to any ultraviolet light. Exposed areas typically develop a red, often painful rash; small, itchy blisters; and scaly skin. It may be present at birth but more commonly develops later in life, sometimes as a result of using certain medications or cosmetics. It may also be a feature of systemic lupus erythematosus.
Treatment includes avoiding ultraviolet light, using sunblocks and covering the skin when outdoors, and avoiding substances that may cause photosensitivity.
A doctor may also prescribe corticosteroids or antihistamines to relieve symptoms.
