The difference between facelift and thread sculpture mainly lies in the surgical method, applicable population, principle of action and other aspects. 1. Surgical method: facelift is mainly through open surgery, stretching, excision of excess loose skin, generally without the help of other materials, but the incision is longer, the range is larger, the trauma is relatively large, the recovery time is longer. Thread sculpture mainly works by embedding synthetic thread material under the skin and pulling the loose skin. 2. Suitable for people: facelift is usually suitable for people over 45 years old with moderate to severe skin laxity, while thread sculpture is suitable for mild to moderate middle-aged people. 3. Principle of action: facelift mainly peels off the subcutaneous tissue, separates the fascial layer, corrects skin wrinkles, tightens myofascial laxity, redistributes and lifts sagging soft tissues, and reshapes the appearance of the face and neck, which requires removal of part of the excess skin. In addition to the short-term suspension and traction effects of thread sculpting, long-term stimulation can form a fibrous coating around the sutures, stimulating collagen fiber proliferation and achieving skin tightening. Both facelift surgery and thread sculpture surgery carry the risk of bleeding, infection, skin necrosis or nerve damage in the surgical area. Therefore, regular hospital visits are recommended. Individualized treatment plan should be chosen according to the age and skin condition of the surgeon, and post-surgical care should be done properly.
