Study on Tegreen 97 and Aging


Monday, April 19, 2010


A recent clinical study showed that Pharmanex Tegreen 97 can actually enhance the appearance of skin.

A couple years ago, scientists wanted to find the long-term effects of green tea on specific characteristics of facial skin. For two years, the scientists randomly administered Tegreen 97 or a placebo to 56 women two times a day. The women’s skin was then tested at six-, 12-, and 24-month intervals.

The randomized, double-blinded, placebo-controlled study, the largest of its kind to date, revealed a strong correlation between Nu Skin’s Tegreen 97 and reductions in skin damage based on different study assessments, including grading from board-certified dermatologists.

In fact, 47% of women who took Tegreen 97 twice daily for two years had moderate or greater improvements in photoaging when compared to placebo. Additional significant self-assessments over baseline included:


Reduction in pore size at 12 months

Increased skin evenness at 12 months

Clinical graders reported the following significant improvements over baseline:


Reduced appearance of small blood vessels (telangiectasias) on the skin’s surface at six and 12 months

Reduced solar damage at six months

Joe Chang, Ph.D., Nu Skin chief scientific officer and executive vice president of product development said, “This landmark research confirms Nu Skin’s philosophy that there is a strong relationship between nutrition and physical appearance. The results from this clinical study illustrate to consumers that the best anti-aging strategy requires a two-pronged approach that focuses on both internal nutrition and external skin care.”

Green tea has been used traditionally in China for thousands of years for its health-preserving and revitalizing power, and modern science has identified polyphenols as powerful antioxidants. One group of polyphenols—catechins—is particularly potent and highly effective in neutralizing free radicals at the cellular level. Nu Skin’s Tegreen 97 contains a proprietary green tea extract containing 97 percent polyphenols, of which 65 percent are catechins. The antioxidant power in one Tegreen 97 capsule is equivalent to seven cups of the traditionally brewed green tea drink and is 99.5 percent caffeine free.

In addition to the Tegreen 97 ingestible supplement, Nu Skin also includes Tegreen 97 in its topical Tru Face Essence Ultra firming serum as part of an antioxidant network to protect rejuvenated skin cells and proteins.
