Wound stitches will leave marks, and even if the stitches are fine, they will inevitably leave scars, so cosmetic stitches will still leave scars, but they will minimize the traces of cosmetic stitches. The size of the scar that will be left after the suture is determined by a number of factors, such as whether the skin at the edge of the wound is neatly dovetailed, the severity of contamination, whether the wound is infected, and whether the patient is a scarred person. Cosmetic sutures actually clean the wound thoroughly and then dock the sutures layer by layer, which is more neat, snug and tight compared to normal sutures, reducing skin tension and scar tissue formation. Moreover, the structure of cosmetic threads is more stable compared to ordinary sutures, and the stimulation reaction to human tissues is weak and less damaging, and thread-hole-like scars are generally not formed on the skin surface. The wound should be changed on time and kept out of water as much as possible during the recovery period. After the scabs fall off, you can apply aloe vera gel or vitamin E, which has the effect of helping to lighten the scars, or you can get a doctor to prescribe scar cream for use. If the scars are more obvious, you can go to the cosmetic department for scar removal treatment after the wounds are healed.
