Photoaging refers to the premature aging of the skin caused by prolonged exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. It is distinct from intrinsic aging, which is the natural, chronological aging process of the skin. The primary mechanism behind photoaging is the damage that UV radiation inflicts on the skin's cellular structures and DNA.
The visible signs of photoaging typically appear on sun-exposed areas of the body, such as the face,
The underlying cellular damage involves the breakdown of collagen and elastin, proteins essential for maintaining the
Preventing photoaging primarily involves reducing UV exposure. This can be achieved through consistent use of broad-spectrum
