Post-operative routine precautions 1. Pay attention to the clean and dry surgical site, avoid touching water and reduce sweating, change medication every other day or daily, contact the main surgeon immediately if there is any discomfort such as redness, swelling, heat and pain in the wound. 2.Minimize the activity of stretching the incision and do not over exaggerate the facial expression, otherwise it will lead to obvious scarring. 3.Use postoperative tension-reducing apparatus (tension reducer, elastic sleeve, elastic bandage, elastic garment, etc.) with pressure that does not affect blood flow to prevent the scar from being stretched wide. The use is started immediately after surgery and needs to be continued for more than six months. Early use of drugs to inhibit scar growth Silicone gel, silicone gel patch, silicone gel ointment (e.g. Schoenkopf, Scarke), and also blood-activating ointment (e.g. Centella asiatica ointment, Xylitol ointment, etc.) can be used, usually 2 days after stitch removal, for more than 3 months. Early intervention if scar growth is found If you find obvious scar growth, you can take various means such as drug closure and laser to intervene as early as possible. 1.Drug closure: The most commonly used one is hormone closure, which is usually used when obvious red scar hyperplasia appears after surgery, and the effect is sure, but it is necessary to pay attention to the injection amount and injection technique to avoid skin depression. 2.Laser treatment: Different laser treatments can be chosen according to the color and shape of the scar, which usually need to be repeated several times. In conclusion, scarring is very difficult to avoid, but beauty can be achieved through the reasonable use of various prevention and treatment techniques.
