Discuss the changes that the skin undergoes during the aging process

What will be an ideal response?

The skin consists of three layers: 1. the epidermis, or outer protective layer, where new skin cells are constantly produced; 2. the dermis, or middle supportive layer, consisting of connective tissue that stretches and bounces back, giving the skin flexibility; and 3. the hypodermis, an inner fatty layer that adds to the soft lines and shape of the skin. As we age, the epidermis becomes less firmly attached to the dermis, fibers in the dermis thin, cells in both the epidermis and dermis decline in water content, and fat in the hypodermis diminishes, leading the skin to wrinkle, loosen, and feel dry. In the thirties, lines develop on the forehead as a result of smiling, furrowing the brow, and other facial expressions. In the forties, these become more pronounced, and "crow's-feet" appear around the eyes. Gradually, the skin loses elasticity and begins to sag, especially on the face, arms, and legs. After age 50, "age spots," collections of pigment under the skin, increase. Blood vessels in the skin become more visible as the fatty layer thins. Because sun exposure hastens wrinkling and spotting, individuals who have spent much time outdoors without proper skin protection look older than their contemporaries. And partly because the dermis of women is not as thick as that of men, women's skin ages more quickly.
