Dr. Aster: Today my topic is all about Wrinkles. Wrinkles are a natural part of aging due to decreased elasticity, increased thinning of skin and decreased fat under skin. Wrinkles are most prominent on sun-exposed skin, such as the face, neck, hands and forearms. Although genetics mainly determine skin structure and texture, sun exposure is a major cause of wrinkles, especially for fair-skinned people. Other factors, such as pollutants and smoking, also contribute to wrinkling. If your wrinkles bother you, you have more options to smooth them or make them less visible. Medications, skin-resurfacing techniques, fillers, injectable and surgery top the list of effective wrinkle treatments. A dermatologist can also recommend medical wrinkle treatments. Thank You.
