Sunburn
Introduction
Sunburn is characterized by erythema and sometimes pain and blisters caused by overexposure to solar ultraviolet radiation. Treatment is similar to that for thermal burns, including cool compresses, nonsteroidal anti-inflammatory drugs, and, for severe cases, sterile dressings and topical antimicrobials. Prevention by sun avoidance and use of sunscreens is crucial. Sunburn results from overexposure of the skin to ultraviolet (UV) radiation; wavelengths in the UVB spectrum (280 to 320 nm) cause the most pronounced effects.
