Common Uses of Hydrogen Peroxide on Skin Water (H2O) containing an extra oxygen molecule is known as hydrogen peroxide (H2O2). When that extra oxygen molecule oxidises, the solution disinfects and bleaches the surface. The process of oxidation generates free radicals, which fight diseases or germs. Hydrogen peroxide has antiviral, antibacterial, and disinfecting activities.
Hydrogen peroxide is a bleach and oxidising chemical that is used in a variety of applications including cleaning, antiseptics, and skincare. It is used as a disinfectant and bleach for the skin at low concentrations (up to 10%). Wounds, acne, and hyperpigmentation have all been treated with hydrogen peroxide. It works by releasing oxygen, which creates foaming, which aids in the removal of dead skin cells. However, there are hazards associated with using hydrogen peroxide, such as skin irritation and impaired wound healing, so doctors do not advocate using it to clean or bleach the skin. Hydrogen peroxide can be harmful if consumed or inhaled.
