Hello, electric negative pressure liposuction is a classic liposuction operation. It uses electric suction or a special negative pressure liposuction machine to insert a liposuction tube into the subcutaneous fat layer through a small incision in the skin, and then uses the suction of electric negative pressure to suck the subcutaneous fat accumulated in the mandible out of the body. Through this operation, you can achieve the purpose of face-lifting and slimming. I hope my answer is helpful to you.
