VelaShape® III is a non-invasive, nonsurgical procedure used primarily to tighten, refine and contour. The combination of IR and vacuum-coupled RF technologies causes deep heating of the fat cells (adipocytes), their surrounding connective fibrous septae, and the underlying dermal collagen fibers. The device is moved across the area of your body that needs treatment, and a vacuum helps move your tissue up, which allows the heat from the infrared light to work more effectively. It also stimulates fibroblast activity and remodels the extracellular matrix.
