Facial surgery suture scar can be improved through drugs, surgery and other ways to improve its appearance, but once the scar can not be completely eliminated. 1. Drug treatment: In the early stage of scar formation, drugs such as silicone gel and allantoin gel can be used to inhibit scar proliferation; for the old scar that has obvious proliferation, we can also consider injecting steroid hormone into the scar to soften and reduce the size of the scar. 2. Surgical treatment: there are mainly keloidectomy with reduction and fine suture, skin abrasion, etc. The keloidectomy with reduction and fine suture is suitable for smaller keloid scars. It mainly reduces the tension of the surgical incision through fine operation, thus reducing the secondary injury and further reducing the degree of postoperative scar proliferation. The treatment of facial keloid scars should be carried out in regular hospitals, and should not be carried out without authorization, so as not to delay the condition. Pay attention to the care of scarred areas on weekdays, strict sun protection, avoid scratching, friction and other mechanical injuries.
