Icing, cleansing and moisturizing after squeezing blackheads is usually necessary and can help the skin repair. If necessary, anti-inflammatory drugs can be used under the guidance of a doctor to prevent infection. 1. Ice: After squeezing blackheads is easy to cause skin damage, skin swelling or pain. It is recommended to use a towel wrapped in ice and put it on the blackheads, which can shrink the local blood vessels and reduce the blood circulation, which is conducive to the swelling and pain subside. 2. Cleaning and moisturizing: The dilated pores left after squeezing out blackheads are easily infected with bacteria and fungi, so you can use povidone-iodine solution to disinfect the blackhead area. At the same time, you can also apply moisturizing cream to strengthen the skin’s moisturizing care, which can help inhibit the regeneration of blackheads. 3. Anti-inflammatory drugs: After squeezing out the blackheads, the skin pores dilate and inflammatory infections are likely to occur. So you need to use anti-inflammatory drugs to prevent infection, such as clindamycin gel and fusidic acid ointment. If you want to deal with blackheads, it is recommended to go to a regular hospital and follow the doctor’s instructions for medication to avoid adverse consequences.
