Baking Soda:
use to exfoliate the skin 1 time a week. Baking soda naturally balances the PH level of your skin. Baking soda is coarse, but not too coarse. It's the best amount of coarse for removing the top layer of dead skin cells, and if applied correctly, it won't cause your sensitive facial skin to become red and irritated. To reap the benefits of exfoliating with baking soda, add a teaspoon of the powder to your facial cleanser, mix well, and massage into skin like you would with a commercial exfoliant. Chemically speaking, baking soda is acid neutral, and acts a mild buffer which means that it has the ability to neutralize other substances it comes in contact with that are acidic (like vinegar) or basic (like soap).
