Wrinkles are folds and lines which appear on the surface of the skin as we age. They can occur anywhere, but usually first begin to appear around the eyes, on the forehead and around the mouth.
As we age, collagen and elastin in the skin begin to deplete, causing it to lose its natural firmness and elasticity.
Laughing, concentrating, squinting or frowning all contribute to the formation of wrinkles because whenever you move your face your muscles contract. Environmental and lifestyle factors ? such as exposure to sunshine, smoking or pollution ? can give rise to lines and wrinkles.
?Crow?s feet? is the common name given to wrinkles which appear at the side of the eyes, stretching out towards the temples. The term ?crow?s feet? developed because of how the lines splay out; in a similar shape to a crow?s claw or foot.
The main cause of crow?s feet is a decrease in the amount of collagen and elastin in the skin. These proteins are responsible for our skin?s elasticity, but production drops as we age.
