Our skin consists of two important proteins called collagen and elastin. Collagen keeps our skin firm and tight. Elastin gives our skin flexibility and elasticity. It allows our skin to stretch, wrist and contract. As we age, our skin produces less elastin and collagen causes our wrinkles. Some people got wrinkles at an early age because of over exposure of UV radiation to the skin. Long term exposure of Ultra violet radiation causes collagen and elastin in our skin to break down. Besides this,smoking and poor nutrition are also the major factors.
