Mark D. Farrar, PhD, et al, followed 50 subjects (13 male and 37 female; 18-65 years of age; Fitzpatrick skin phototypes I and II) who took 1,080 mg green tea catechins (GTC), which is the equivalent to 5 cups of tea/day, with 100 mg vitamin C (n = 25) or placebo maltodextrin (n = 25) daily for 12 weeks.

Sachs, MD, and her colleagues at the department of dermatology, University of Michigan, Ann Arbor, to conduct research on the effectiveness of five well-known skincare products. Results of the study appeared in the article, “Hypo-collagenesis in photoaged skin predicts response to anti-aging cosmeceuticals” (Journal of Cosmetic Dermatology, June 2013).
