Wrinkles are a natural element of ageing on the skin. Wrinkles are most prominent on sun-exposed areas such as the face, neck, hands, and forearms. Although genetics determines skin structure and texture, sun exposure is the leading cause of wrinkles, especially for fair-skinned people. Environmental pollution and smoking also contribute to skin wrinkling. Today, there are many different options for individuals who are bothered by their wrinkles to correct or make them less visible. Effective wrinkle treatments include drugs, skin rejuvenation techniques, fillers and plastic surgery.
