The influence of ultraviolet radiation on the aging process of the skin

Skin as the largest organ of the human body is constantly exposured to solar radiation. Photoaging describes the influence of ultraviolet radiation (UVR) on the skin exposed to light. A typical histopathological indicator of skin aging is the phenomenon of elastosis, which is the accumulation of amorphous elastin and tropoelastine in the reticular layer of the dermis. The presented study summarizes pathogenesis and clinical features related to chronic exposition of skin to UVR.
