I have had this done a couple years ago and have no idea what specific filler was used but loved the results. It was suggested based on my increasing concern of aging around the mouth and jawline. Which brings up another question. Do fillers along the jawline help to reduce the appearance of a sagging jawline? Will it make things worse? Most importantly, I have had 1 round of scultra in January. Have not noticed any improvement in my area of concern. Do I need to wait till after the 3rd round?
