Good facial cleansing
Removing makeup is very important to attack this problem. Makeup clogs our pores, even more so if we are touching up with compact powder around the day. You must clean your face perfectly in the morning and at night, in order to control this problem.
Wash your face with liquid soap preferably, it contains much less soda than a normal one. This will make your PH not unbalance as much as if you do it with a stick.
