A new clinical trial shows that green tea extracts do not prevent skin damage caused by ultraviolet (UV) rays. Study participants were randomly assigned to receive 1350 mg of green tea extract with 50 mg vitamin C or placebo twice daily for 3 months. Taking green tea extracts provided no protection against sun damage or the longer-term effects of UV rays. These findings are contrary to the results of an earlier clinical trial.
