7.Acne
Hydrogen peroxide is an ingredient in a number of ointments and mixtures to zap pimples. And they seem to work just as well as benzoyl peroxide, the mainstay acne treatments. But the chemical can be harsh, especially if you have scars, cuts, or sores on your face. Talk to your doctor before you use it in any form on your skin.
8.Disinfectant
Hospitals use it because it’s especially good at killing a parasite called cryptosporidiosis (crypto) that spreads in human poop. Even bleach can’t seem to easily get rid of these stubborn pathogens. Hydrogen peroxide may also work against the norovirus, which is both hard to kill and very contagious. More research is needed to know how well it works as a decontaminant.
