Simply put, the more sun exposure you have had, even as a child, the earlier your wrinkles will appear. I have seen patients in their early 20s with wrinkles. These are the beach babies -- they spend hours each day working on their tans, and their future wrinkles. And today's freckles become tomorrow's age-spots. It is the ultraviolet light (UV) contained in sunlight that is responsible for much of the aging of the skin. Chronic UV exposure causes wrinkles, splotchy pigmentation, visible capillaries (telangiectasia) and loose, rough skin. UV causes damaging substances called free radicals to be produced. UV also depresses the natural antioxidants in the skin, contributing to more damage. Ultraviolet light damages your genetic material (DNA) every time you are in the sun. To convince yourself, compare the skin on the back of your hands with the skin on the inside of your upper arm. The upper arm looks better in everyone.
