Unlike the Brazilian butt lift, vacuum therapy (also known as vacuotherapy) is noninvasive and tones your tush without the use of incisions. Vacuum butt therapy is a massaging technique that helps lift and contour the buttocks via a suction device equipped with glass cups. After a mini massage, two small suction cups are moved over the thigh and buttocks area, manipulating the tissue, then two larger suction cups are sealed over each side of the butt for approximately 30 minutes.
