Sun damage

Solar elastosis

The sun's ultraviolet radiation breaks down the connective tissue — collagen and elastin fibers — that lies in the deeper layer of the skin. Without that supportive connective tissue, the skin loses its elastic quality. This condition is called solar elastosis (e-las-TOE-sis). Skin affected by solar elastosis has deep wrinkles that don't disappear when stretched. The skin also may look yellow.
