Why do wrinkles appear in old age?

The appearance of wrinkles, that is, furrows or folds in the skin, is one of the characteristic symptoms of aging. Immediately below the epidermis are connective tissue fibers that provide support and smoothness to the skin. They are composed of collagen, a highly resistant biological material that is manufactured by specialized cells in the dermis called fibroblasts.

Over the years, collagen , apart from its reduction in production, loses structural rigidity and yields, which leads to the formation of wrinkles. This process is enhanced by another dermal protein, elastin, whose deterioration translates into a reduction in its natural elasticity; and by the loss of fatty tissue. One of the causes of skin breakdown is exposure to ultraviolet light from the sun.
