Like me, most women don’t like to have blackheads. To know how to avoid them, we need to learn how blackheads are being formed. To start ,with we need to know about pores. The more we know about pores, the more we can effectively manage all 20,000 of them on our face. Pores are very small openings on the surface of your skin, where sweat and oil are secreted. They become clogged when oil, dirt, makeup or pollutants accumulate, forming visible blackheads. It is very important that we need to clean our face as often as we need to. We should wash our face after wearing make-up or after exposure to pollutants.
