Hello, hope you are well. To improve your neck contour and jawline, I would suggest chin augmentation with an implant, and a neck lift. Chin augmentation can also be done with filler, but you should know that route is not permanent or durable. A chin implant can be placed under local anesthesia in the office transorally (through a small incision concealed inside the mouth) so that there is no visible scar. Neck lifts come in different forms, but you could consider a minimally invasive route which would be FaceTite/NeckTite + submental "chin" liposuction under local anesthesia. Alternatively, a short scar neck lift can be performed under general anesthesia which allows more aggressive contouring of deep neck fat and sometimes muscle. Hope this helps! Best,Dr. Tower
