sun radiation (ultraviolet radiation, visible light, and infra-red radiation)
, air pollution, tobacco smoke, nutrition, some less well-studied factors, and cosmetic products.
What is an example of extrinsic aging?
Extrinsic ageing of skin is a distinctive declination process caused by external factors, which include
ultra-violet radiation, cigarette smoking, air pollution

How does chronic inflammation affect intrinsic aging?
Inflammation is a defense mechanism. It serves as the body's natural way of protecting itself against injury and infection. However, when it occurs on a loop, it can
