Background Photoaging, ultra violet (UV) induced skin aging is a gradual process that
depends on the time and intensity of solar radiation. Aim The aim of this paper was to review …

The routine and often unavoidable exposure to solar ultraviolet (UV) radiation makes it one
of the most significant environmental DNA-damaging agents to which humans are exposed …

The human skin is exposed daily to different environmental factors such as air pollutants and
ultraviolet (UV) light. Air pollution is considered a harmful environmental risk to human skin …

Abstract The Free Radical Theory of Ageing, was first proposed by Denham Harman in the
mid-1950's, based largely on work conducted by Rebeca Gerschman and Daniel Gilbert. At …

Skin is continuously exposed to a variety of environmental stresses, including ultraviolet
(UV) radiation. UVB is an inherent component of sunlight that crosses the epidermis and …

Due to its ability to cross the epidermis and reach the upper dermis where it causes
cumulative DNA damage and increased oxidative stress, UVB is considered the most …

Skin aging is characterized by changes in its structural, cellular, and molecular components
in both the epidermis and dermis. Dermal aging is distinguished by reduced dermal …

The aging process starts directly after birth and lasts for the entire lifespan; it manifests itself
with a decline in an organism's ability to adapt and is linked to the development of age …

Photoaging is characterized by a chronic inflammatory response to UV light. One of the most
prominent features of cutaneous photoaging is wrinkling, which is due primarily to a loss of …

Autophagy is an essential cellular process that maintains balanced cell life. Restriction in
autophagy may induce degenerative changes in humans. Natural or pathological aging of …
