Extrinsic ageing of skin is a distinctive declination process caused by external factors, which include ultra-violet radiation, cigarette smoking, air pollution, among others. Of all extrinsic causes, radiation from sunlight has the most widespread documentation of its negative effects on the skin.
Prolonged exposure is associated with the development of skin cancers, photoaging or premature skin aging, immune suppression, and eye diseases like cataracts. [14] [15] Given these dual effects, public health organizations emphasize the importance of striking a balance between the benefits and risks of UV exposure.
UVA rays are able to penetrate deeper into the skin than UVB rays, damaging the dermal layer as well as the epidermal. The dermis is the second major layer of the skin and it comprises collagen, elastin, and extrafibrillar matrix which provides structural support to the skin. However, with constant UVA exposure, the size of the dermis layer ...
Exposure to non-ionizing ultraviolet light is a risk factor for developing skin cancer (especially non-melanoma skin cancers), sunburn, premature aging of skin, and other effects. Despite the possible hazards it is beneficial to humans in the right dosage, since Vitamin D is produced due to the biochemical effects of ultraviolet light.
Ultraviolet (UVA and UVB) radiation in the sun's rays can cause sunburn in varying degrees, early ageing and an increased risk of skin cancer. [14] UV exposure can cause patches of uneven skin tone and dry out the skin. It can reduce skin's elasticity and encourage sagging and wrinkle formation.

The most common health hazard of radiation is sunburn, which causes between approximately 100,000 and 1 million new skin cancers annually in the United States. [ 3 ] [ 4 ] In 2011, the World Health Organization (WHO) and the International Agency for Research on Cancer (IARC) have classified radiofrequency electromagnetic fields as possibly ...
