Wrinkles are a natural part of aging. As you grow older, your skin gets thinner, drier and less elastic, and it becomes less able to protect itself from damage. As a result, wrinkles, lines and creases form in your skin. Although genetics are the most important determiner of skin texture, spending too much time in the sun is a major contributor to wrinkles.
Causes of the Aging face: Wrinkles are caused by a combination of factors — some you can control, others you can’t:
- Age. As you get older, your skin naturally thins and becomes less elastic and more fragile. Decreased production of natural oil makes your skin drier and appear more wrinkled.
- Exposure to ultraviolet (UV) light. Ultraviolet radiation markedly speeds up the natural aging process and is the primary cause of early wrinkling. Exposure to UV light breaks down your skin’s collagen and elastin fibers, which lie in the deeper layer of skin (dermis). Without the supportive connective tissue, your skin loses its strength and flexibility. As a result, skin begins to sag and wrinkle prematurely.
- Wrinkles at rest due to repeated facial expressions. Facial movements and expressions, such as squinting or smiling, lead to fine lines and wrinkles. Each time you use a facial muscle, a groove forms beneath the surface of the skin. And as skin ages, it loses its flexibility and is no longer able to spring back in place. These grooves then become permanent features on your face.
- Loss of fat: Fat in the deeper layers of your skin, which gives the skin a plump appearance, starts to lessen. This causes loose, saggy skin and more pronounced lines and crevices.
- Smoking. Smoking can accelerate the normal aging process of your skin, contributing to wrinkles. This may be due to changes in the blood supply to your skin.
