A non-invasive butt lift involves restoring and increasing buttocks volume with your own buttock fat using a vacuum therapy . The vacuum therapy uses ultrasound waves that lifts the buttocks , stimulates the muscles and mobilizes the fat permanently. It is a non-invasive technique that promotes natural lifting and tightening of the skin beneath the surface. The treatment uses ultrasound waves to target the deepest layers of skin and stimulate collagen growth. The deep layers of skin that are targeted during a treatment are the same ones that would be tightened during a surgical butt lift.
