As we age, the constant replacement of cells that occurs throughout life slows down, and more imperfect cells are produced. Changes in the skin reflect this process. The dermis, the layer of skin right below the outer layer, thins and loses elastin and collagen, proteins that keep the skin flexible. Muscles and fat cells become smaller. The skin sags and becomes dry and wrinkled. Blood vessels, tendons, and bones are more visible. Age spots appear. The risk of skin cancer increases, and the ability to maintain a constant temperature is diminished.
