Chances are you have a bottle of hydrogen peroxide tucked away in your medicine cabinet, buried somewhere behind your product graveyard—the spot where you stash beauty products you don’t really use but think you might want someday. Well, now there’s a reason to resurrect that unassuming bottle of hydrogen peroxide—actually, several reasons.
Scroll through for all of the ways you can use this underrated $2 product in your beauty routine!

Hydrogen peroxide ($2) is the all-in-one mouthwash you didn’t know existed. Not only does it kill the germs that cause bad breath, reduce bacteria buildup, and diminish gum inflammation, but the peroxide also acts as a bleaching agent, making it an excellent teeth whitener. Some even say it helps alleviate toothaches and canker sores. Just swish it around for 30 to 60 seconds. If you do this every day, consider diluting hydrogen peroxide to make a half-water, half–hydrogen peroxide mixture to swish.

Hydrogen peroxide can be used to treat acne in the same way it treats cuts and scrapes. Dab it on a breakout to kill the bacteria and cleanse the area. Or if you have a particularly breakout-prone area (say your chin or jawline around that time of the month), you can put hydrogen peroxide on a cotton ball and use it as a toner to combat bacteria buildup and prevent pimples from forming.

Looking for a better way to clean your makeup brushes? (Answer: Yes, always.) Huffington Post suggests soaking your synthetic brushes in a 1:1 hydrogen peroxide and water mixture for five minutes, and then just rinse and dry for germ-free makeup brushes. This is also a good idea for disinfecting your toothbrush. You can even rinse your toothbrush in hydrogen peroxide to kill staph bacteria and other common bathroom germs.

When dark polish stains your nails or they’re just looking a little dull and weathered, turn to hydrogen peroxide. It’s a natural whitener that will lighten discoloration. Two ways to try it: Rub a cotton ball saturated in the solution over your nails, or soak them for a few minutes.

Make your own toothpaste out of hydrogen peroxide and baking soda. Just mix three parts baking soda with one part hydrogen peroxide until a paste forms. This DIY version works great in a pinch, and it’s a natural alternative to traditional store-bought whitening toothpaste.
