Sunburn — red, painful skin that feels hot to the touch — usually appears within a few hours after too much exposure to ultraviolet (UV) light from sunshine or artificial sources, such as sunlamps. Sunburn may take several days or longer to fade.
Intense, repeated sun exposure that results in sunburn increases your risk of other skin damage and certain diseases. These include dry or wrinkled skin, dark spots, rough spots, and skin cancers, such as melanoma.
You can prevent sunburn and related conditions by protecting your skin. This is especially important when you're outdoors, even on cool or cloudy days. If you are sunburned, home remedies and treatments can help soothe your skin as it heals.
