1. How to use baking soda to wash your face: wet your face with water. Squeeze a pea-sized amount of facial cleanser into the palm of your hand and sprinkle a small amount of baking soda powder on top of the facial cleanser. Use your hands to work the facial cleanser into lather and massage the facial skin. After massaging for 1-2 minutes, rinse the foam off your face with water and apply toner and lotion.

2. Use baking soda to wash your face once a week. Baking soda is alkaline. Alkaline substances have a certain irritation to the skin when exposed to water, which will decompose the oil on the surface of the skin, causing irritation and damage to the skin.
