Wrinkles As skin ages, collagen and elastin, fibers that keep the skin firm, weaken. The skin looks loose and lax, becomes thinner, and loses fat, so that it looks less plump and smooth. While all these changes are taking place, gravity is also at work, pulling at the skin and causing it to sag. The sun is the major cause of unwanted changes in the skin with aging. How wrinkled your skin becomes depends largely on how much sun you have been exposed to in your lifetime.
Cigarette smoking can also contribute to wrinkles.
Wrinkles also depend on your parents - the tendency to wrinkle is inherited. The good news is that many wrinkles can be prevented. If you have already sun-damaged your skin, you will still benefit from beginning sun protection as an adult. It's never too late. These dilated facial blood vessels may be related to sun damage.
