The Internal and External Factors in Aging Skin

The aging process is influenced by both internal and external factors. Although some are unavoidable, some can be prevented. All of the factors play a role in aging skin.

Internal Causes of Aging Skin

The internal causes of aging skin are not entirely avoidable. They are natural processes of the body that start in your mid-twenties as the production of collagen in your body decreases. At the same time, the elastin in your skin – the natural spring – weakens. Together, the reduction in collagen production and weakened elastin cause many of the external signs of aging, such as:

  • Fine lines and wrinkles
  • Thinning skin
  • Hollowed cheeks and eye sockets
  • Dry, itchy skin

While you can’t make the body produce more collagen or do exercises to strengthen the elastin in the skin as you could a weakening muscle, you can use collagen injections to temporarily fill-out the skin. You can also use elastin-boosting skin care products to help restore the skin’s spring.

External Causes of Aging Skin

Although the internal causes of aging are unavoidable, you can avoid or significantly reduce the impact of some of the external causes of aging.

Sun Exposure

Sun exposure is the leading cause of aging skin. You’ve no doubt seen men and women with thick, leathery skin marred by age spots and skin cancer lesions. This is often a result of repeated and extended sun exposure without adequate protection. The sun’s UV rays damage the skin’s ability to repair itself. To avoid sun damage, always wear sunscreen and avoid lengthy sun exposure during peak sun, usually between 10AM and 3PM. If you must be outside, wear a hat, apply sunscreen with at least SPF 30 frequently, and cover your arms and legs. If you go into the water, reapply sunscreen after you dry off, even if the sunscreen claims to be water resistant.

Smiling, Frowning, and Other Expressions

We express ourselves through our facial expressions. Unfortunately, the muscles that allow us to move our faces can also causes wrinkles in the skin. You shouldn’t avoid expressing yourself through your face, but some evidence indicates that frowning is more harmful to the skin than smiling. Stress reduction exercises and practices, such as yoga or meditation, can reduce your need to frown and help prevent frown lines.

Gravity

Gravity has a powerful impact on the body, and it simply can’t be avoided. You can reduce the effects of gravity on your bones and muscles through weight-bearing exercise. See your doctor for advice on adopting an exercise regimen.

Sleeping in the Same Position

Most people have a preferred sleep position. If your preferred sleep position is your side or your stomach, you may be damaging the skin on your face through repeated pressure. If possible, try to shift positions or train yourself to sleep on your back.

Smoking

Researchers all agree that smoking is bad for your overall health, including your skin. The toxins in cigarette smoke increase the dryness in your skin, which can contribute to a dry, leathery appearance. In addition, smoking robs the body of vital nutrients and accelerates the aging process. If you smoke, quitting is the only solution.
