1.Avoid the sun. It’s the No. 1 cause of wrinkles, with dozens of studies documenting the impact. In one study that looked at identical twins, New York plastic surgeon Darrick Antell, MD, found sun exposure was even more important than heredity. Siblings who limited sun time had fewer wrinkles and looked younger overall than their sun-worshiping twins.
2.Wear sunscreen. If you must go out in the sun, the American Academy of Dermatology says, wear sunscreen! It will protect you from skin cancer, and help prevent wrinkles at the same time.
3. Don’t smoke. Some of the research is still controversial, but more and more studies are confirming that cigarette smoke ages skin — mostly by releasing an enzyme that breaks down collagen and elastin, important components of the skin. Sibling studies done at the Twin Research Unit at St. Thomas Hospital in London found the brother or sister who smoked tended to have skin that was more wrinkled and up to 40% thinner than the non-smoker.
4. Get adequate sleep. Yale dermatologist Nicholas Perricone, MD, says that when you don’t get enough sleep, the body produces excess cortisol, a hormone that breaks down skin cells. Get enough rest, Perricone says, and you’ll produce more HGH (human growth hormone), which helps skin remain thick, more “elastic,” and less likely to wrinkle.
5. Sleep on your back. The American Academy of Dermatology (AAD) cautions that sleeping in certain positions night after night leads to “sleep lines — wrinkles that become etched into the surface of the skin and don’t disappear once you’re up. Sleeping on your side increases wrinkles on cheeks and chin, while sleeping face-down gives you a furrowed brow. To reduce wrinkle formation, the AAD says, sleep on your back.
6. Don’t squint — get reading glasses! The AAD says any repetitive facial movement — like squinting — overworks facial muscles, forming a groove beneath the skin’s surface. This groove eventually becomes a wrinkle. Also important: Wear sunglasses. It will protect skin around the eyes from sun damage — and further keep you from squinting.
