Face Tightening Mask: You should use a mask, twice a week to keep the size of the pores small. After cleansing the facial skin, spread the mask on the face with your fingertips and let it dry up completely. Once it has dried up, then damp it a bit with some warm water and rub a washcloth gently over the mask. Then rinse it off first with warm water followed by cold water. Lastly, apply a natural skin toner like tea tree oil on the face. The natural properties of the oil will shrink the pores and give you a smooth skin.
