Sunburn (First-Degree Burns)

A sunburn is skin damage from the sun's ultraviolet (UV) rays. Most sunburns cause mild pain and redness but affect only the outer layer of skin (first-degree burn). The red skin might hurt when you touch it. These sunburns are mild and can usually be treated at home. Even one sunburn, though, increases your risk for developing melanoma.

Your skin type affects how easily you become sunburned. People with fair or freckled skin, blond or red hair, and blue or light-colored eyes usually sunburn easily. Your age also affects how your skin reacts to the sun. The skin of children younger than age 6 and adults older than age 60 is more sensitive to sunlight.
