Wrinkles are the lines, creases, and folds that appear on the skin, primarily as part of the natural aging process. They are most prominent on sun-exposed areas of the body, such as the face, neck, hands, and forearms. Over time, the skin loses its elasticity and moisture, leading to the formation of these visible signs of aging. While wrinkles are a natural part of growing older, they can also be influenced by various environmental and lifestyle factors. Advances in cosmetic and plastic surgery offer a range of treatments that can reduce the appearance of wrinkles, helping individuals maintain a more youthful appearance.
