Patients in our NYC practice are examined by a doctor prior to undergoing CoolSculpting for fat loss as the amount of fat may vary signficantly from one patient to the next and that may determine how many treatments they need. In addition, the number of applicators may be different and how they are overlapped and fitted for contouring / sculpting...CoolSculpting.
