1, different treatment concepts not only save lives, but also pay special attention to beauty in cosmetic suture, adopt various technical means to reduce scar formation, and in order to prevent scar hyperplasia, patients will be given scar-removing cream after stitches are removed.

2. Different technical methods. In traditional surgical treatment of wounds, large needles and thick threads are directly used for traction and suture. In cosmetic suture, subcutaneous tension reduction technology is used to suture small needles and thin lines without tension, which keeps the skin beautiful and reduces scars.

3. The scar size of suture materials is different, which has a great relationship with the materials used for suture. For wounds of the same size, the thicker the suture, the larger the interval, the less the number of stitches, and the more obvious the scar (centipede-like scar). Ordinary suture cosmetic suture material ordinary silk thread polymer composite thread thickness No.4, 1, No.0, No.5-0, No.6-0, No.7-0 foreign body reaction is heavier and lighter. Needle-eye nodules and scars are obviously not as big as postoperative scars. Generally, the healing time of surgical suture is as thick as that of pencil lead, so the traces after healing are usually obvious. The suture used for cosmetic suture is relatively thin, and the trace after healing is small.
