Wrinkles are a natural part of aging, especially for the face, neck, hands and forearms. But some people are more prone to wrinkles based on sun-exposure and other factors. Although genetics mainly determine skin structure and texture, sun exposure is a major cause of wrinkles, especially for fair-skinned people. Pollutants and smoking also contribute to wrinkling.
While some people welcome their wrinkles, as a sign of character, if your wrinkles bother you there are things you can do to minimize developing wrinkles.
