For UVB LEDs most promising applications are in the field of medical skin therapy and novel concepts of horticulture and plant growth (irradiation of plants for the generation of phytamines or to reduce hormone-like mixtures). UVC applications focus on disinfection of air, surfaces and water at ...

Many natural compounds improving plant cells resistant to oxidative stress by the harnessing of solar energy may be also used to protect human cells. Although many nature plants have shown photoprotective effects on skin, the mechanisms underlying of the effects are still ambiguous.This study ...
Vitamin D3 (cholecalciferol) is a steroid hormone precursor and is synthesised when skin is exposed to ultraviolet B radiation. It is also found in a limited number of foods, especially oily fish. The other form of the vitamin, vitamin D2 (ergocalciferol), is found in dietary plant sterols...
Intrinsic aging is manifested by a decrease in the biosynthesis of biocomponent proteins and hormone secretion [2]. On the other hand, extrinsic aging is caused by photoaging caused by polluted air or ultraviolet (UV) rays [3]. Exposure to UVB causes DNA damage and destruction of the protein...
It is abundant in mature red plant fruits such as tomatoes, papayas, pink grapefruits, pink guavas, and watermelons [5]. Natural lycopene is plentiful and is used in health product supplements [6]. These red fruits, especially tomatoes, are also rich sources of vitamins, minerals, fiber, ...
