Although most people love the warmth and light of the sun, too much sun exposure can significantly damage human skin. There is evidence that sunlight can be good for us, helping the body to make Vitamin D that keeps our bones healthy. But, like many things in life, too much of a good thing can sometimes be harmful. Too much sun can damage the skin, and this may only start to become apparent later in life. The sun’s heat dries out areas of unprotected skin and depletes the skin’s supply of natural lubricating oils. In addition, the sun’s ultraviolet (UV) radiation can cause burning and long-term changes in the skin’s structure.
The most common types of sun damage to the skin are:
Sunburn — Sunburn is the common name for the skin injury that appears immediately after the skin is exposed to UV radiation. Mild sunburn causes only painful reddening of the skin, but more severe cases can produce tiny fluid-filled bumps (vesicles) or larger blisters.
