The new 4th generation of FLX Thermage uses patented monopolar RF technology to create a uniform heating effect in the deep collagen – rich layers of the skin to 4.3mm, stimulating collagen to proliferate gradually. With addition of the 3D vibration sensation and interspersed cooling bursts, it gives more comfort during treatment, achieving skin lifting in a short period of time while improving the skin’s texture and creating a sharp contour.
