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 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 (AAD) 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 at 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.
7. Eat More Fish Particularly Salmon
Not only is salmon (along with other cold-water fish) a great source of protein one of the building blocks of your skin. it's also an awesome source of an essential fatty acid known as Omega-3. Perricone tells WebMD that essential fatty acids help nourish skin and keep it plump and youthful, helping to reduce wrinkles.
8. Eat More Soy
So far, most of the proof has come from animal studies, but research does show certain properties of soy may help protect or heal some of the Sun's photoaging damage. In one recent human study, published in the European Journal of Nutrition, researchers reported that a soy-based supplement (other ingredients included fish protein and extracts from white tea, grapeseed, and tomato, as well as several vitamins) improved skin's structure and firmness after just six months of use.
9. Trade Coffee For Cocoa
In a study published in the Journal of Nutritionin 2006, researchers found cocoa containing high levels of two dietary flavanols (epicatchin and catechin) protected skin from sun damage, improved circulation to skin cells, affected hydration, and made the skin look and feel smoother.
10. Eat More Fruits And Vegetables
The key, says Kraus, are their antioxidant compounds. These compounds fight damage caused by free radicals (unstable molecules that can damage cells), which in turn helps skin look younger and more radiant, and protects against some effects of photoaging.
11. Use Moisturizer
"Women, especially, are so concerned with antiaging products they often overlook the power of a simple moisturizer. Skin that is moist simply looks better, so lines and creases are far less noticeable," .
12. Don't Over Wash Your Face
According to dermatologists at the University of Maryland Medical Center, tap water strips skin of its natural barrier oils and moisture that protect against wrinkles. Wash them off too often, and you wash away protection. Moreover, unless your soap contains moisturizers, you should use a cleanser instead.
