Course and prognosis: Sunburn presents as erythema (areal redness of the skin) caused by excessive UV-B irradiation. Within a few hours, sunburn can lead to acute complications such as blistering, edema (swelling), and elevated temperature. Symptoms usually appear within six hours of radiation exposure and peak after 12 to 24 hours. Sunburn usually heals after one to two weeks. It is a risk factor for skin aging and the development of precancerous skin lesions (actinic keratosis, a precancerous lesion; risk factor for squamous cell carcinoma) and squamous cell carcinoma of the skin, basal cell carcinoma (BCC; basal cell carcinoma; 10 times more common than melanoma), melanoma).
