Exofoliation is required to scrub away dead skin cells that dull your complexion and clog your pores. Baking soda is an inexpensive exfoliator that gently scrubs your skin. Add a few tablespoons of baking soda to plain yogurt or your choice of facial cleanser. Apply to your face and massage in circular motions, concentrating on oily or rough areas, then rinse thoroughly with water. If your skin is oily, you should gently exfoliate four to five times a week, whereas more sensitive skin should be exfoliated less often.
