Rub ice cubes to close pores Whenever you do a facial or cleanse your face or take steam for your face, your pores will happen. Opening up the pores will remove black or white heads. Then rub your face with ice cubes so that the pores will close. When you apply icecubes, your face becomes numb and blood circulation stops for a while. As the numbness decreases, blood circulation increases rapidly thereby giving a glowing face.
