In our youth obsessed culture, there are countless creams, lotions, vitamins, herbal remedies, and personal care devices that are advertised as rejuvenators aging. Unfortunately, very few of these anti-aging skin medications are supported by any rigorous clinical and laboratory research data. Now, a new perspective, randomized, placebo-controlled, double-blind clinical study strongly suggests that the antioxidant polyphenols from green tea may actually help protect the skin from damage caused by exposure to ultraviolet (UV) light, and can also help improve overall skin quality.
In this new clinical research study, which appears in the current issue of the Journal of Nutrition, 60 adult female volunteers were randomized to either intervention or control group skupinu.Žena in the intervention group consumed fortified drink green tea polyphenols (1402 mg catechins of green tea per day), while women in the control group consumed a drink that is identical in appearance, but that does not contain any green tea polyphenols. Protecting the skin from UV radiation damage, skin structure and skin function were then tested in all these women at the time the study began, six weeks into the study and again 12 weeks in the studio.
of skin testing with UV light exposure sufficient to cause redness than normal unprotected skin was performed in both groups of women. (This "erythema response" is a sign of acute UV-induced skin injury.) In the intervention group of women volunteers, redness of the skin in response to standard doses of UV light was reduced by 16 percent at 6 weeks and 25 percent at 12 weeks. In addition, elasticity, roughness, scaling, density and water content in the skin of all improved during the study among women who were secretly randomized to receive daily supplements of green tea polyphenols (as compared to women in the control group who received a placebo drink). Daily consumption of green tea polyphenols has also been shown to increase blood flow and oxygen delivery to the skin, with a maximum improvement of blood flow occurs about 30 minutes after consumption of green tea polyphenols.
In short, the daily consumption of green tea catechins is shown in this innovative prospective, randomized, placebo-controlled, double-blind studies to significantly improve skin injury response to UV light exposure, and appears to significantly improve several important clinical aspects of the overall skin quality. In addition to promoting healthier and more youthful appearing skin, green tea polyphenols, as I explained in previous columns (and my recent book, Cancer Prevention Guide for the human race), are also associated with improved cardiovascular health, and may also help to reduce the risk of certain types of cancer.
