Green Tea has recently garnered a lot of attention for the
antioxidant polyphenols that it contains. Both oral and topical
administration of green tea polyphenols in human models has shown their
ability to prevent signs of ultraviolet-induced damage. Topical
treatment of human skin with green tea polyphenols has been shown to
prevent the DNA damage that leads to skin cancer. Clearly, green tea is a
powerful anti-oxidant, and there is good evidence to support its use in
the general population to help prevent photoaging and to decrease the
risk of skin cancer.
Green Tea Study Highlights:
* Recent studies suggest that "tea polyphenols are strong antioxidants, more powerful than Vitamin C and Vitamin E"
* Studies further suggest that tea polyphenols have an
anti-inflamatory effect. "Topical green tea polyphenols reduced
UV-induced erythema and sunburn cell formation in human skin."
* Studies suggest that topical antioxidants "should supplement the
natural antioxidant protection present in the skin and provide
supplemental reserves as oxidative stress depletes antioxidant stores."
