The basic technology used in Venus Freeze is the same as that used in many other devices such as Exilis, Thermage, Invasix, Alma Accent, Velashape, Pelleve, and many more. This is called radiofrequency. The essential principles are that the distance between the transmitting and receiving electrodes will effect the depth of penetration. Tissue exposed to radiofrequency energy will experience thermal increases and heat. The heat can be used to accomplish desired goals of skin contraction or fat reduction or even skin destruction. The real secret remains in how to deliver that energy and how to monitor the energy. Thus the variety of devices in the marketplace. Venus Treatments claim that their proprietary method of alternating the distance between the electrodes will allow variable depth treatment and well as minimize the discomfort experienced by the patient. In addition, they add magnetic pulses for their supposed benefits. The new generation of machines, called Venus Legacy, adds suction to draw the skin into the machine (similar to other technologies such as Endermologie) and increases the distance between and the direction of the electrodes.
