Question: which one is good for skin baking soda or baking powder?
Answer: Baking soda is a mild base and mild abrasive, so a paste (2 parts baking soda to 1 part water) can act as a skin cleanser and exfoliant. The dry powder can also absorb excess skin oil. ... Baking powder is a mixture of baking soda and one or more mild acids, often with a bit of corn starch.
