Scar tissue can be done as follows: 1, if it is a mild scar, you can prefer body lotion to apply, and then do a light massage, usually within six months there will be a significant recovery. 2, if there is a more obvious scar, you can prefer to go to the Department of Dermatology and Cosmetology to do the relevant scar removal treatment. However, it should be pointed out that this treatment is only better for the scar that protrudes from the surface of the skin. If the scar is depressed, the effect is not particularly good. 3, if the scar is very large, very obvious, or accompanied by severe pain, it is necessary to carry out surgical excision. The principle of the surgery is to remove the scar tissue through the original incision, and completely remove the proliferated scar tissue, including the scar on the surface of the skin as well as the scar under the skin. After complete removal, a cosmetic suture is made. Of course, a thorough debridement and hemostasis should be performed before the cosmetic suture is placed. Adequate anti-infective treatment should be done after the suture, because this type of suture drainage is not particularly good, and is prone to infection, which can lead to failure of treatment if there is significant fluid accumulation and infection.
