Scar is a local symptom that physical, biological, chemical and other factors damage human skin and soft tissue, resulting in serious damage to skin and soft tissue, which cannot be completely repaired by itself and is replaced by fibrous tissue, affecting appearance and function. "Scar" brings great physical pain and mental pain to patients, especially the scars left after burns and serious trauma. The years of scar hyperplasia almost made patients miserable. Then the atrophic phase makes the patient unrecognizable and dysfunctional, causing great physical and mental obstacles. The acne scars left by adolescence have left an indelible "youth mark".
Once a scar is created, it will not disappear. Several common scar treatment methods: scar excision and non-invasive suture; Repair the scar after normal skin expansion with soft tissue expander; Drug injection in scar; Scar grinding; Local spraying and coating can improve appearance and reduce scar hyperplasia. But one thing is certain, no treatment can completely eliminate scars. American scholars used scar antibody to study the immunotherapy of scar, and threatened to win the Nobel Prize, but three years later, this immunotherapy has not been applied to clinic, that is, it has not achieved the expected results. Visible scar treatment still has a long way to go.
