Polymorphous light eruption - what does this mean
Polymorphous light eruption is an inflammatory skin condition caused by exposure to ultraviolet radiation from the sun or other sources. it is characterized by an itchy, red rash that appears on areas of skin that have been exposed to the sun, usually within a few hours of exposure. the rash may appear as small bumps or patches of redness, and can be accompanied by swelling and blistering.
What happens during the disease - polymorphous light eruption
Polymorphous light eruption is an acquired photosensitivity disorder caused by an abnormal reaction of the skin to sunlight. it is thought to be triggered by uva radiation, which activates antigen-presenting cells in the skin, leading to an increased production of inflammatory cytokines and the release of autoantibodies. this results in an inflammatory reaction and skin lesions, which typically appear within hours of sun exposure.
Polymorphous light eruption - Prevention
Polymorphous light eruption is best prevented by avoiding direct sun exposure during peak hours of the day, wearing protective clothing such as wide-brimmed hats, and using sunscreen with an spf of 30 or higher. additionally, it is important to use sunglasses to protect the eyes from uv radiation.
