Objectives

The purpose of this study was to examine the bactericidal efficacy of hydrogen peroxide (H2O2) on Cutibacterium acnes (C. acnes). We hypothesize that H2O2 reduces the bacterial burden of C. acnes.

Methods

The effect of H2O2 was assessed by testing bactericidal effect, time course analysis, growth inhibition, and minimum bactericidal concentration. To assess the bactericidal effect, bacteria were treated for 30 minutes with 0%, 1%, 3%, 4%, 6%, 8%, or 10% H2O2 in saline or water and compared with 3% topical H2O2 solution. For time course analysis, bacteria were treated with water or saline (controls), 3% H2O2 in water, 3% H2O2 in saline, or 3% topical solution for 5, 10, 15, 20, and 30 minutes. Results were analyzed with a two-way analysis of variance (ANOVA) (p < 0.05).
