Scar, refers to the uneven scar? If so, cosmetics alone can't be repaired. Because when acne occurs, most of them grow in the shallow layer, and some grow in the deep layer of skin dermis. When acne grows in the dermis, it will cause the scar tissue in the dermis to shrink, leading to the depression of the epidermis and the formation of pits. If the swelling and inflammation (that is, the inflammation subsides) no longer appear in the near future, the soft and thin pit formed by acne can be improved by external care and beauty. For example, insist on hot compress, exfoliation and blood circulation massage, gradually soften and peel off the locally hardened epidermis of pits, and promote the normal growth of collagen. If it takes a long time, it will be through plastic surgery. The above suggestions suggest that you go to a more formal beauty institution for consultation and nursing. If it's not a pit, I recommend you to use acne cleanser+acne cream+repair solution, which can slowly fade acne marks.
