Skin Aging: Implications of UV Radiation, Reactive Oxygen Species and Natural Antioxidants
Bristy Ganguly, Manisha Hota, Jyotsnarani Pradhan
Abstract
Skin aging is an inescapable phenomenon that leads to a functional decline of the skin along with emergence of characteristics features such as coarse skin, wrinkles, loss of elasticity and an overall aged appearance. While chronological aging is inevitable occurring with time, photoaging is contributed by Ultraviolet radiation and reactive oxygen species principally which can boost the skin aging process. These processes can however be ameliorated with the help of treatment strategies, one of them being supplementation with antioxidants. This chapter summarizes diverse mechanisms underlying skin aging with regards to Ultraviolet radiation and reactive oxygen species along with role of antioxidants in impeding these processes. Further, it provides a glimpse towards possible future explorations and challenges dominating the field of skin aging.
