Baking Soda for Acne: Those who want to know how to treat acne with baking soda should begin by mixing the baking soda with water to make a paste. This paste should be very similar in consistency to toothpaste, as it should be soft enough that it can easily be rubbed over the skin. You should also make sure that your face is wet before applying the baking soda, as this will ensure that the paste is able to be spread.
