Trauma suturing is a very specialized technique, and cosmetic suturing will be more delicate and perfect under the premise of ensuring the patient’s life; try to make the wound just a “trace”, thus reducing the patient’s psychological burden! All skin wounds, if deeper than the dermis, will leave scars of varying degrees. Those who guarantee not to leave “traces” are either liars or magicians! For example, the instruments we use are special plastic instruments to reduce tissue tension, and the sutures are fine absorbable or non-absorbable cosmetic threads, which are thinner than a hair. The sutures are fine absorbable or non-absorbable cosmetic sutures, thinner than a hair. The subcutaneous reduction sutures are used during the operation, so the scar left after the surgery is relatively small, not scarless. In addition, after the surgery, I will advise the patient to use anti-scar medication to minimize and fade the scar formation.
