Why does the visible effervescence of hydrogen peroxide often mislead users regarding its effectiveness on a wound?

Answer

The visual evidence suggests aggressive cleaning and pathogen destruction

The strong visual cue of hydrogen peroxide bubbling and foaming when applied to exposed tissue gives users the powerful impression that the substance is working effectively to clean and disinfect the wound aggressively. For many years, this visible effervescence was directly equated with successful antimicrobial action, making people feel they were ensuring the wound was clean. However, this foaming is merely the rapid chemical decomposition into water and oxygen gas, a process that is not selective and damages healthy cells just as easily as surface pathogens, thus misleading the user about the true net benefit to the healing process.
