Buried wire face lift, the more common current wire sculpture. Buried wire lifting is a cosmetic surgery technique that is performed by burying wires within different layers of the body surface tissue to achieve aesthetic results such as lifting and tightening of loose and drooping tissues. The main purpose is to lift the skin through the pulling force of the wire to achieve a rejuvenating effect. The maintenance time after buried wire lift is related to the design of the surgery, the amount of wiring, the absorption of the material and the post-operative care. In the early stage, it mainly relies on the pulling force of the wires to lift up the sagging tissues. In the later stage, it mainly relies on the process of gradual absorption of the wires in the body to stimulate the skin to produce new scar and collagen to form a pulling force to lift the facial tissues. The effect of submerged thread lift is immediate and the maintenance time is about 1-2 years. However, each person is different and the length of time it lasts varies. People with more expressive faces may have a shorter maintenance time. However, the maintenance time is not unlimited and will be absorbed after a certain period of time. To achieve a lasting anti-aging effect, it is necessary to re-embed the threads from time to time to extend the maintenance time.
