Yogurt is a very gentle exfoliant that can be used for all skin types. It contains lactic acid that prevents the skin from drying. Spread a small amount of yogurt on your face and leave it on for about 20 minutes. Rinse it off with warm water to open your pores and remove other dirt underneath the pores. Close your facial pores with cold water. Use a soft towel to dry your face with gentle pats instead of rubbing the towel over your face.
