Protective effects of green tea extracts on photoaging and photommunosuppression

Abstract

Background: Health benefits of designed functional foods using dairy fermented products in co-production with medicinal herbs are under comprehensive investigations. Yoghurt has triggered a functional food revolution while green tea and Moringa oleifera represent precious source of high content of various types of antioxidants and micronutrients. Oxidative stress and lipid peroxidation are suggested mechanisms involved in lead toxicity. The aim of present study was to assess protective effects of green tea and moringa leave extracts and their bio-yoghurts against lead acetate-induced oxidative stress in male rats by following liver weight and enzymes and lipids profile.

Ex vivo evaluation of radical sun protection factor in popular sunscreens with antioxidants

“…20,21 Combinations of vitamins C, E, and polyphenolic extracts have been shown to have photoprotective effects in humans and pigs. [22][23][24][25] The second line of ''active'' protection with antioxidants can potentially boost the body's natural antioxidant reserve and quench free radicals generated from the residual UV rays that have bypassed the sunscreen filter and reach the skin.…”

Validation of Medicinal Herbs for Skin Aging

“…[117,118]. Nichols and Katiyar [52] reported that green tea polyphenols, catechin, epigallocatechin, and epigallocatechin-3-gallate, function favorably as sunscreen supplements to protect the skin from the adverse effects of UV radiation-induced inflammation, oxidative stress, and DNA damage including the risk of developing skin cancers.…”
