Sunburn is skin damage caused by the ultraviolet rays in sunlight. People with pale skin are most vulnerable, but it can also affect those with dark skin. The ultraviolet rays destroy cells in the outer layers of skin and damage the deeper layers.
The affected skin becomes red and tender and may blister; later, the dead skin cells are shed by peeling.
Sunburn, particularly severe sunburn in childhood, increases the risk of developing solar keratoses (scaly spots on the skin) and skin cancer later in life.
Mild sunburn can usually be treated by cooling the skin, applying moisturizing or anti-inflammatory lotions, and taking pain relievers. Severe sunburn may need medical treatment
