It's normal to have acne marks. Nowadays, the skin that is not healthy in cold weather freezes more obviously, because the surface skin is thin, so don't worry. There are protruding marks on the nose because the pores are not contracted in time after acne. Generally speaking, it is due to improper handling of acne. I suggest you drop a few drops of white vinegar in clean water every day when you wash your face, which has the function of anti-inflammatory and sterilization. Then, be sure to moisturize and use more lotion and lotion. Lavender flower water and tea tree essential oil are recommended, which is very good. Oh, I'm a acne muscle myself, and I'm much better now. These are all my own experiences. Humidifier can be used in the room and the effect is very good! I hope you can solve this problem as soon as possible.
