Would I vial be enough for your treatment? Yes you have a small issue. After the treatment you should expect severe pain, swelling, brusing, and possible transient nerve damage. After several weeks of healing, you are not likely to be able to discern a difference in your neck contour. Many treatments at 4 to 6 weeks intervals are needed to achieve this difference. In the study that was the basis of the FDA approval, investigator were allowed to treat with up to 6 sessions of Kybella to achieve the pateint goals. Most pateints required all 6 sessions. At the end of the study, 40% of patients were dissatisfied with results. Compare this with a neck liposuction which is a single minimally invasive procedure. It can be done under local anesthesia with minimal brusing and down time. A single session is highly effective whic most patients achieving their goal. Do the math, in many cases, neck liposuction is less expensive than 4 to 6 sessions of Kybella.
