Blackhead needles, also known as acne needles, have two heads, one with a needle and the other with a ring, and are used to clear blackheads, closed pimples and pustular acne. The acne needle should be disinfected with 75% alcohol before use. When cleaning blackheads, since they are directly exposed outside the skin, you can use the ring on one end of the acne needle to gently press and pull out the blackheads, and pay attention to the disinfection of iodine volts after squeezing. When clearing closed acne, use the tip of the acne needle to pierce the epidermis vertically, then press and pull with the ring on the other end to clear out the closed acne. Pustular acne can be cleared by using an alcohol lamp to burn the red tip to pierce the pus head, and then gently squeeze out the pus with a cotton swab. It is necessary to pay attention to the dangerous triangle of the face and try not to squeeze hard, and after clearing it, it is best to apply antibiotic-based ointments such as topical fusidic acid ointment in conjunction.
