Q: Does hydrogen peroxide help heal cuts, or is that a myth? I heard that when it “bubbles” it is cleaning the wound.
A: It is unnecessary and may actually damage skin and retard healing. That’s also true of other harsh antiseptics such as rubbing alcohol, iodine, and hexylresorcinal. Use hydrogen peroxide only if directed to do so by a doctor or other health care provider.
Simple irrigation is the key to cleaning a wound—just hold it under cool running water. Use soap on the surrounding skin, trying not to get it on the wound itself. If you see dirt particles, remove them with tweezers.
