This non-surgical, non-invasive treatment for cellulite has four components, which together have been shown to be effective in tightening and smoothing skin: radio frequency energy (RF), infrared light energy, mechanical vacuum, and automatic rolling massage. · Infrared light (IR) heats the tissue superficially · Bi-polar radio frequency (RF) heats tissue up to 20 mm in depth · Vacuum technology ensures the precise delivery of energy · Mechanical manipulation improves lymphatic drainage and cellulite smoothing     1) Virtually painless non-surgical and non-invasive treatment 2)No downtime so you can resume daily activities immediately 3) Precise heating ensures an effective treatment 4) Safe for all skin types and all skin colors 5)0-0.07 MPA adjustable vacuum can suck the target area into the space between the two rollers which are actually 2 electrodes. This can make the treatment accurate and effective. It can also make the treatment more comfortable. The auto-rollers can do massages as well 6)5MHz bipolar radio frequency(RF) with two rollers can penetrate into the layer of0.5-1.5 cm below the skin to work on adipose tissue effectively 7) 700-2000nm infrared light can heat the connective tissue to accelerate the regeneration of collagen and elastic fibers. It can also improve blood circulation and lymph circulation to promote the metabolism
