Scars can be removed, and there are many ways to remove scars, which are broadly divided into two categories: the first category is non-surgical, which can be done by injecting hormones plus local anesthetic drugs into the base of the scar, which can inhibit the proliferation of scar fibroblasts, thus achieving the effect of making the scar smaller. Special wavelength lasers can also be used to irradiate the scars, which can also inhibit the growth of collagen fibers, thus reducing the size of the scars. The second type is surgery that can remove the scar directly, if the excision is small, then it can be directly sutured, if the excision is large, then it needs to be repaired with a skin graft. If the scar is really too big and it is a functional area, you can also implant dilators under the normal skin before surgery, wait for the dilators to expand the skin for about 1-2 months, then remove them, and then use the expanded skin to repair the scar trauma.
