A study conducted at the University of California, Los Angeles, has promising new implications for acne treatment. Researchers found that when resveratrol is combined with benzoyl peroxide, the acne-fighting effects last longer.
Resveratrol is a grape extract with antioxidant and antimicrobial properties that is already a popular antiaging skin care ingredient. Red wine also contains high amounts of resveratrol. Benzoyl peroxide is very effective against P. acnes bacteria, but only kills the bacteria for a short time after application to the skin. When paired with resveratrol, and applied in vitro to cultured bacteria, the combination showed high initial antibacterial activity but, most importantly, also inhibited bacterial growth for a sustained length of time. The opportunity to extend the effects of benzoyl peroxide makes this an exciting discovery for the skin care profession.
The study was sponsored by the Women’s Dermatologic Society and the National Institutes of Health.
