Doctors Taylor, Yu, Champer and Kim of UCLA, in the September 2014 Journal of Dermatology and Therapy, report that the antioxidant properties of resveratrol, found in grapes, when combined with benzoyl peroxide, enhances its ability to kill Propionibacterium acnes, the bacteria that causes acne. Dr. Jenny Kim, professor of clinical medicine in the department of Dermatology at the David Geffen School of Medicine at UCLA states, “It was like combining the best of both worlds and offering a two-pronged attack on the bacteria.”
Benzoyl peroxide is an oxidant that creates free radicals that kill the acne bacteria. Resveratrol is an antioxidant. Dr. Emma Taylor of the same department, said they initially thought the two substances would cancel each other out, and “This study demonstrates that combining an oxidant and an antioxidant may enhance each other and help sustain bacteria-fighting activity over a longer period of time.”
