Fine lines and wrinkles are common signs of aging that appear as creases or folds in the skin, usually around areas of facial expression such as the eyes, mouth, and forehead. They form as a result of a combination of factors, including the natural breakdown of collagen and elastin, repeated facial movements, and environmental damage. Over time, the skin’s ability to regenerate and retain moisture decreases, leading to the visible signs of aging. Treatment options can help smooth out these lines, restoring a youthful and smooth appearance.
