Previous Next 6 of 10 Solar elastosis

Ultraviolet radiation breaks down the connective tissue — collagen and elastin fibers — that lies in the deeper layer of the skin (dermis). Without the supportive connective tissue, the skin loses its elastic quality. This condition, known as solar elastosis (e-las-TOE-sis), is characterized by yellowed, thickened skin with deep wrinkles that don't disappear with stretching.
