Without photos, it is difficult to comment in any but the most general way. What can be said is that If there is sagging and jowl formation of the lower face and jawline, robust HA fillers have a proven track record (when injected by experienced physician injectors) for achieving nonsurgically and noninvasively immediate results for straightening and defining the jawline and treating jowls along the jawline. And if the problem is accordion lines and parallel laugh lines of the lower cheeks around the mouth, this, too, can be improved by injection of an appropriate cohesive, low viscosity HA filler properly injected in the region. By contrast, you would be wise to exercise a great deal of "buyer beware" when evaluating so many of the here-today-gone-tomorrow, relatively expensive "bells and whistles" light and energy-based treatments, etc. that are backed far more by heavy marketing hype than hard science. To lessen the chance for "buyer's remorse," you would be wise to consult with a board certified cosmetic dermatologist. Hope this helps. Best of luck.
