Polymorphous light eruption
Polymorphic light eruption is a common reaction to sunlight (ultraviolet light) that occurs in “light-sensitive” individuals. Small red pimples and blisters appear on the skin within 1 to 4 days after exposure to sunlight.
They disappear within 2 weeks. The cause is unknown. Some experts think it is a type of delayed allergic reaction. Controlled ultraviolet light exposure may reduce some of the symptoms.
