Exfoliant

Actress Emma Stone told Elle that she uses baking soda mixed with face wash to create a gentle exfoliant for her skin. You can also mix baking soda with lemon juice, a mild acid, to create a foamy exfoliating scrub that not only improves complexion, but can also remove a spray tan, soften skin, and help to neutralize acids.

Breath Freshener

Dissolve a teaspoon of baking soda in half a glass of water, then swish and spit the mixture to get clean, fresh breath.

Hair Clarifier

You can use baking soda to remove the crud that accumulates in your hair as a result of normal shampooing. Doing this once per month will leave your hair softer and shinier, but beware that baking soda has a very high pH and can throw off the pH balance of your hair.

Body Soak

Adding half of a cup of baking soda to bath water can neutralize skin acids, clear away oils, and cut through perspiration and odors. It will leave your skin feeling soft and looking radiant.

Brush Cleaner

Baking soda is a great way to remove oils and caked on makeup from cosmetic brushes. Soak your brushes in a mixture of one teaspoon of baking soda in a single cup of water, rinse them and let them dry. The next time you use your brushes, your makeup will go on more evenly.

Nail Cleaner

Baking soda makes a great cleaning and polishing agent for both finger nails and toe nails. Whether you are going for a pedicure or a manicure, use baking soda on a nail brush to scrub under your nails and polish your cuticles. Make a paste of three parts baking soda to one part water. Rub the paste into your nails to exfoliate and polish them.

Deodorant

Mix four tablespoons of baking soda with up to ten drops of a pleasant-smelling essential oil to create an underarm deodorant that you can apply with a brush or your hand. You may need to reapply this deodorant throughout the day, but it contains no dangerous chemicals and will keep you smelling fresh.

Acne Treatment

A drawing agent is a substance that pulls moisture from a pimple to help dry it out and reduce inflammation. A baking soda paste will do this when it comes to surface acne. It will dry the blemish and sooth surrounding inflammation, helping to hide any redness.
