Thank you for your question. Vanquish uses a form of energy called radio-frequency (RF) to gently heat the skin to 1010F and the underlying fat to 1200F, which in turns destroys the fat cells. The sensors built into the Vanquish device can read your body fat and, from that reading, can calculate the amount of RF energy needed to destroy your fat cells. After these fat cells have been destroyed another type of cell, in your body, called a phagocyte, comes along and digests them. If you are considering having Vanquish treatments, I would consult first with a board certified dermatologist or plastic surgeon who has extensive experience and training in this modality.
