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 optimal design of the electrodes and the concurrent application of vacuum allows for deeper and faster heat penetration. In turn, this promotes an increase in circulation, lymphatic drainage, cellular metabolism and collagen depositing. It also stimulates fibroblast activity and remodels the extracellular matrix. The result: A localized reduction in skin laxity, volume and an overall improvement in skin structure and texture.
