In winter I take steam on my face and after that I scrub my face and washed with lukewarm water and applied Nivea cream .After days I got lots of black and white heads on my nose and cheeks and my skin is getting dry. (1) As steaming open the pores how to I close them after that.(2) I want to know is it right to do scrub after steaming.(3) lastly how to remove the black and white heads. Should I do or stop the steaming of my face.
