Injectable hyaluronic acid-based volumizing fillers, such as Voluma XC, Stylage XXL and Neauvia Intense Flux work well for re-volumizing and recontouring the lower cheeks and jawline. The results are seen at the time of treatment and typically engender an immediate "Wow!" reaction. I personally gave up using Sculptra quite a few years ago for a number of reasons, some of which are suggested by your question. The results are quite gradual and typically three treatment sessions, as in your case, are required to achieve the desired improvement, and the treatments are relatively expensive. If sufficient time has not passed since your last treatment session, it would be prudent to wait to see if you get any additional improvement. If after a few weeks, however, there is no change or insufficient improvement, you would be wise to consult with a board certified aesthetic physician and be sure to ask to see his/her personal before and after photos before agreeing to proceed. Finally, be cautious if offered fat injections for a number of reasons. First, they tend to be a relatively expensive proposition. Secondly, it is a two step minimally invasive process, where the fat is drawn from the tummy, hips or thighs and then reinjected with larger cannulas into the face. Thirdly, the fat once separated from its original blood supply often does not last as long as promised. And finally, whatever fat does survive retains the characteristics of the location from which it was drawn. Meaning that with aging, if your belly fat was meant to expand, the fat now in the face from the belly is likely to expand, as well. Best of luck to you.
