Sunburn

Definition

A sunburn is reddening of the skin that occurs after you are overexposed to the sun or other ultraviolet light.

Alternative Names

Solar erythema; Burn from the sun

Considerations

The first signs of a sunburn may not appear for a few hours. The full effect to your skin may not appear for 24 hours or longer. Possible symptoms include:

Symptoms of sunburn are usually temporary. But the damage to skin cells is often permanent, which can have serious long-term effects. These include skin cancer and early aging of the skin. By the time the skin starts to become painful and red, the damage has been done. Pain is worst between 6 to 48 hours after sun exposure.

Causes

Sunburn results when the amount of exposure to the sun or other ultraviolet light source exceeds the ability of melanin to protect the skin. Melanin is the skin's protective coloring (pigment). Sunburn in a very light-skinned person may occur in less than 15 minutes of midday sun exposure, while a dark-skinned person may tolerate the same exposure for hours.
