Blackhead is composed when the wastes in the pores come in contact with the air. For people who are having trouble with blackheads. If you squeeze it out with your hands, it will fill up the empty space back later on with another blackhead and it will also enlarge your pores. So don’t ever squeeze your blackheads. When I was in elementary school I had lots of blackheads because I played tennis and I didn’t wash my face properly after playing sports.  I almost gave up trying to get rid of the blackheads. Someone told me that the best preventation to keep away the blackheads is washing your face cleanly. I started using organic soap for a year and the most of my blackheads disappeared. Make sure you wash around your nose really clean. Some good organic soaps are the ones made out of plants. Scrub your face at least once or twice a week to reduce blackheads. To tighten your pores, you can make your own egg yolk face mask. Mix egg yolk with little bit of flour in a bowl and put it on your face and leave it for 30 minutes and you will feel the difference. Good luck everyone.
