The team observed that the bacteria did indeed die from this treatment but that the treatment’s effectiveness was short-lived, lasting less than a day. The researchers also treated the bacteria with resveratrol. They observed that resveratrol did not necessarily lead to the bacterium's death that causes acne but somewhat slowed bacterium growth for several days. The research team classified this phenomenon as a long-term effect.
The researchers then compared the combination treatment of resveratrol and benzoyl peroxide and observed a dramatic reduction in bacteria growth and an increase in the killing of bacteria. It now appears that resveratrol may be used as a new therapeutic option for treating acne.
