(5) Skin Disorders

Many changes on the cellular level occur with aging. Can you explain these further?

The dermis (middle layer of the skin) suffers a loss of elastic tissue, becomes less vascular, and decreases its ability to withstand minor trauma.

The result is easier bruising (purpura), less ability to “rebound,” and more wrinkles.

The nerves, microcirculation, and sweat glands undergo a gradual decline, predisposing to decreased temperature regulation. Nails undergo a slow decline in growth, with thinning of the nail plate, ridging, and splitting.
