Don't smoke! -Smoking robs your skin of precious moisture and causes premature (early) wrinkles. Smoking can speed up the normal aging process of your skin, contributing to wrinkles. These skin changes may occur after only 10 years of smoking. The more cigarettes you smoke and the longer you smoke, the more skin wrinkling you're likely to have. And smoking doesn't cause wrinkles only on your face. Smoking also is associated with increased wrinkling and skin damage on other parts of your body, including your inner arms.
