All About Green Tea

Green tea is derived from the steaming and drying of the tea plant Camellia sinesis. It contains the polyphenol epigallocatechin-3-gallate (EGCG), which has been shown to have remarkable preventive effects against skin cancer and photoaging.

In the journal Preventive Medicine, it was reported in a 10-year study of 419 patients in Japan that the first incidence of patients who had consumed more than 10 cups of green tea per day was 7.3 years later for females and 3.2 years later for males when compared to people who had consumed less than 3 cups per day.

Unfortunately, considering that one 8 oz. cup of green tea contains about 20-40 mg of caffeine, ten-cup consumption may not be entirely good for your skin, as prolonged exposure to caffeine has been suggested to thin the skin.

So there were a bunch of jittery, longer lived Japanese with thin skin and less skin cancer. Hmmmm….

But this is taking Green Tea orally. What about topical application?
A 2003 study in the Journal of Nutritional Biochemistry reported that green tea reduces UVB-induced inflammation as measured by double-fold skin swelling, and this is with topical application. Nice…so next time you have a sunburn – put chilled green tea bags on your face.

In addition, a 2001 study in the journal Carcinogenesis, topical application of EGCG to human skin resulted in decreased oxidative stress and an increase in antioxidant enzymes after UV irradiation. A further 2003 study in Molecular Epidemiology and Cancer Prevention found that the polyphenols in green tea prevent UVB-induced depletion in antioxidant enzymes experienced after UVB exposure in mouse skin.

According to Dr. Leslie Baumann’s Cosmetic Dermatology, no contact allergies have been reported from green tea, so it is a safe ingredient. Green tea is an excellent ingredient for the skin that exhibits many beneficial effects for the skin when consumed orally, including helping to fight against skin cancer and photoaging.

Green Tea is one of the active ingredients in my number two recommended product, Revitol.
