We aimed to investigate the mechanism by which EGCG promotes skin hydration by measuring hyaluronic acid synthase (HAS) and hyaluronidase (HYAL) gene expression …

Protective effect of green tea catechin against urban fine dust particle-induced skin aging by regulation of NF-κB, AP-1, and MAPKs signaling pathways. Catechin / ˈ k æ t ɪ tʃ ɪ n / is a flavan-3-ol, a type of natural phenol and antioxidant.It is a plant secondary metabolite.It belongs to the group of flavan-3-ols (or simply flavanols), part of the chemical family of flavonoids.. 12. To boot, when applied topically, the benefits of polyphenols can help to repair damaged skin and restore elasticity to prematurely aging skin.

The present study tested the hypothesis that UVR affects the catechin levels in the skin of healthy volunteers after consumption of green tea and how catechins in the plasma are related to their presence in skin tissue samples. Urine, skin tissue and fluid were analysed for catechin content and skin fluid for PGE2 and 12-HETE by liquid chromatography coupled to tandem MS. A total of fourteen completing subjects were supplement compliant (twelve female, median 42.5 years, range 29-59 years). The catechins found in green tea are powerful antioxidants that can protect your skin against sun damage and reduce redness, as well as improve its hydration, thickness and elasticity. Dark chocolate contains over twice the amount of catechin found in berries while barley, raisins, red wine and rhubarb are also good sources of catechins. The name of the catechin chemical family derives from catechu, which is the tannic juice or boiled extract of Mimosa catechu (Acacia catechu L.f).

Epigallocatechin gallate (EGCG) is a catechin and an abundant polyphenol in green tea. These chemicals can be found in foods like grapes, pomegranates, green tea, and even red wine. Although several papers have evaluated EGCG as a cosmetic constituent, the skin hydration effect of EGCG is poorly understood. They are powerful for fighting illness and disease when included in your diet. Levels of catechin are concentrated in foods like raw apples, apricots, nectarines, pears and plums with skin, blackberries, red raspberries, cranberries, cherries and broad beans. Red grapes In an open oral intervention study, 11 subjects consumed green tea and vitamin C supplements daily for 3 months.
