Baking soda is a common household item with literally hundreds of uses, including the ability to help heal scars. Baking soda is composed of sodium bicarbonate crystals which gently exfoliate skin when used as a cleansing scrub. Just mix a few teaspoons of baking soda with enough water to form a thick paste then massage into skin where scars are present. Once applied, you should leave the mixture on for a minute or two. This will allow the soda to cleanse pores and help prevent further blemishes. After a couple of minutes, wash your face in lukewarm water and apply a good natural moisturizer like rose hip seed, jojoba, coconut, or olive oil.
