<p>Hydrogen peroxide&nbsp;is a mild antiseptic used on the&nbsp;skin&nbsp;to prevent infection of minor cuts, scrapes, and burns. It may also be used as a&nbsp;mouth&nbsp;rinse to help remove&nbsp;mucus&nbsp;or to relieve minor&nbsp;mouth&nbsp;irritation (e.g., due to canker/cold sores,&nbsp;gingivitis). This product works by releasing oxygen when it is applied to the affected area. The release of oxygen causes foaming, which helps to remove dead skin and clean the area. This product should not be used to treat deep wounds, animal bites, or serious burns.</p>
