We are more than familiar with wrinkles. It's a natural part of aging. In other words, one day we will all have wrinkles on our face, as well as neck, hands and forearms. The major causes of wrinkles include age, UV light exposure, pollutants and smoking.
Wrinkles: what are they?
Wrinkles are the lines and creases that form in your skin. Some wrinkles can become deep crevices or furrows and may be especially noticeable around your eyes, mouth and neck. It is a natural sign of aging. Some wrinkles begin to form in your 20s or 30s.
What makes your skin wrinkled: age, UV light exposure and smoking
Wrinkles are caused by a variety of factors. Some of them you can control, but others you can't.
  • Age. As you get older, your skin naturally becomes less elastic and more fragile. As your skin secretes less natural oils, it becomes dry and makes it appear more wrinkled. Fat in the deeper layers of your skin diminishes. This causes loose, saggy skin and more-pronounced lines and crevices.
  • UV light exposure. Ultraviolet radiation, which speeds the natural aging process, is the primary cause of early wrinkling. In fact, exposure to UV light can break down your skin's connective tissue. Without the supportive connective tissue, your skin loses strength and flexibility. Skin then begins to sag and wrinkle prematurely.
  • 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.
  • Repeated facial expressions. If you are the type of people who love to make facial movements and expressions, chances are that you have more fine lines and wrinkles on your face than your peers. As skin ages, it loses its flexibility and is no longer able to spring back in place. Thus the lines and grooves become permanent features on your face.
