Bactericidal efficacy of hydrogen peroxide on Cutibacterium acnes

Abstract
The purpose of this study was to examine the bactericidal efficacy of hydrogen peroxide (H 2 o 2 ) on Cutibacterium acnes (C. acnes). We hypothesize that H 2 o 2 reduces the bacterial burden of C. acnes. Methods The effect of H 2 o 2 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% H 2 o 2 in saline or water and compared with 3% topical H 2 o 2 solution. For time course analysis, bacteria were treated with water or saline (controls), 3% H 2 o 2 in water, 3% H 2 o 2 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). Results Minimum inhibitory concentration of H 2 o 2 after 30 minutes is 1% for H 2 o 2 prepared in saline and water. The 3% topical solution was as effective when compared wi
