Liposonix uses focused ultrasound, just like Ulthera or Ultherapy. The sound waves can be focused at very deep tissues with pinpoint precision. There is no question that the technology works, and works well, but their are some limitations. Pain management can be a real problem, and without proper anesthesia, the complete treatment cannot be completed. One can dampen the energy, and increase the number of passes, but this will increase the cost and take much longer. It should also be noted that diet and exercise are very important, because without it, the patient will not see as much improvement, and certainly will not retain the loss. We have removed up to 3 inches with one treatment!
