Green Tea, Black Tea and White Tea

green tea. Significant amounts of research have established that tea, including black, green, and white tea, has many intriguing health benefits. Dozens of studies point to tea’s potent antioxidant as well as anticarcinogenic properties. White tea leaf extract is extracted from the minimally processed buds and leaves of green tea. There is research showing that white and green teas have the highest concentration of antioxidant properties (via their polyphenol and flavonoid content) of all teas. However, a good deal of this research is on animal models, which do not directly relate to effects on human skin. There is only limited information about tea’s effect on skin. Polyphenols are the active ingredients in green tea and possess antioxidant, anti-inflammatory and anticarcinogenic properties. Studies have suggest that green tea polyphenols (GTP) can prevent ultraviolet (UV)-B-induced immune suppression and skin cancer induction. Green tea and the other teas (e.g., white tea, which is what green tea begins as) show a good deal of promise for skin, but they are not the miracle that cosmetics and health food companies make them out to be. The bioavailability and biotransformation of tea polyphenols, however, are key factors limiting these benefits in vivo in humans. Current research also indicates that white and green teas have similar amounts of the polyphenol epigallocatechin-3-gallate (EGCG), which is the main antioxidant in tea, can prevent collagen breakdown and reduce UV damage to skin.
