Although it will cost a little more, it is quite cost-effective to save the trouble and cost of scar plastic surgery in the future. Compared with the general suture, plastic surgery suture will be finer, less traumatic and better healing surface, and plastic surgeons will also give you more knowledge of wound care, so that your wound can recover better.
