Ordinary facial cleansers generally do not have the effect of removing blackheads. A small number of facial cleansers with scrubs have a certain effect of removing blackheads by reducing the keratinization of hair follicles. Blackheads usually appear in the nose, forehead and other parts of the pores are clogged sebum is oxidized by the air to blacken the formation, so remove blackheads can directly remove the clogged sebum particles, but also improve the state of the pores, so that sebum is not easy to clog. If you remove clogged sebum grains or blackheads directly, you can remove them by softening the sebum grains with a blackhead expeller and rubbing them in. It is not recommended to squeeze out blackheads by hand, tweezers, etc. It is also not recommended to clean blackheads with alkaline, irritating products to avoid irritating the skin to induce folliculitis. To improve the state of pores, it is best to go to a hospital dermatology department and use topical medications to improve follicle keratinization, such as retinoic acid ointment and adapalene gel, under the guidance of a doctor, or use laser treatment to reduce pores, or use a cleansing mask to help remove the thicker layer of aging keratin so that sebum grains can be easily discharged from the skin surface.
