1. Can't Stop Mother Nature
As we age, our skin cells begin to divide at a slower rate and the outer layer of our skin, or the dermis, begins to thin. Additionally, the fat cells stored below the dermis lose their collagen and elastin--which keep our skin supple and smooth--resulting is drooping skin and wrinkles. Other natural factors which we cannot control, such as gravity or the movement of our facial muscles, can also add to the formation of wrinkles.
2. Reproductive Hormones Help Fight Wrinkles
Another natural factor leading to the cause of wrinkles is a decrease in the production of hormones, particularly in women. Studies have shown that a lack of estrogen can lower the levels of collagen in the skin up to 2 percent per year and decrease the thickness of the skin about 1 percent per year. As a result, as women reach menopause or are effected by other hormonal changes, they may expect to see more wrinkles as well.
3. The Sun is the Skin's Worst Enemy
Dermatologists estimate that the sun is responsible for about 90 percent of the symptoms of premature aging. UV radiation permanently damages delicate collagen fibers in the skin, and can stimulate the production of too much elastin, causing the skin to become too stretchy. Wearing a sunscreen with a minimum 15 SPF is essential for everyone, but even more important for children, as the majority of damage caused by UV radiation occurs before the age of 20.
4. Some Radical Molecules
Free radicals are naturally occurring molecules which cannot be avoided completely. They are created when we breathe in pollution, when we are exposed to UV light or x-rays, when we eat preservatives, particularly nitrates as well as hydrogenated oils and when we smoke. In excessive amounts, free radicals can rob the body of vital vitamins and minerals and damage genetic tissue, disrupting the normal process of cell rejuvenation and creating wrinkles. Eating foods high in antioxidants can help protect you from the damage of free radicals.
5. Just Say No
Smoking is a major factor in premature aging as the chemicals in tobacco cause the blood vessels to narrow in the dermis. As the blood flow is lessened, your skin is depleted of necessary oxygen and vitamins. Smoking not only damages the skin on your face, but can also cause skin to droop on other areas of your body, particularly the inner arms. Smoking also destroys elastin and collagen, causing skin to sag and wrinkle.
