A Randomized Controlled Trial of Green Tea Beverages on the in vivo Radical Scavenging Activity in Human Skin

Abstract: Background: Oxidative stress plays an important role in the pathogenesis of various skin diseases. Thus, the antioxidant network of the skin relies on the uptake of exogenous antioxidants to ensure cell protection against radical formation. Green tea is one of the main sources of polyphenolic antioxidant compounds, but only few data are available on its cutaneous antioxidant effects. Methods: The radical scavenging properties of Benifuuki and Yabukita green tea were investigated in the human skin. Thirty-two p… Show more

“…Tea polyphenols are a very important component of tea. Studies showed that tea polyphenols have a strong scavenging effect on oxygen free radicals [ 14 , 15 ]. Tea polyphenols can sequester lipid peroxidation free radicals during the peroxidation process, lower polyphenolic free-radical content, and interrupt free-radical oxidation chain reactions, thereby effectively removing free radicals [ 14 ].…”

“…Empirical evidence suggests relationships between fluid intake and skin properties [7, 8]. An additional intake of water seems to influence skin barrier parameters like stratum corneum hydration (SCH), in particular in individuals with lower prior water consumption [9, 10].…”

“…In this regard, it may be interesting that cutaneous lycopene can also be determined noninvasively by Raman spectroscopy [32], where gender-related differences in basal carotene and lycopene levels have recently been observed.…”
