1. Mix 2 teaspoons of baking soda and 1 teaspoon of warm water in a small bowl. Use a clean finger to stir the ingredients until a soft paste forms.
2. Splash your face thoroughly with warm water. Dip your fingers into the baking soda paste. Apply the paste to your wet face using a gentle circular motion. Cover your entire face with the paste.
3. Rinse your face thoroughly with warm water, splashing the water over the skin repeatedly until your face rinses clean. Pat your face dry with a clean towel. Don't let the exfoliating cleanser dry if you have sensitive or acne-prone skin. The granules are more abrasive when dry. Rinse the wet cleanser from your skin with water to clean and lightly exfoliate sensitive skin without irritating it. [source: SFGate.com]
