I have a receding chin, so the boundary between my neck and jaw is blurry. Will getting chin filler help bring out the line?

Whenever I take a profile photo, my chin is set back deeply—a typical case of a receding chin. This makes my mouth appear relatively protruding, and the boundary between my jaw and neck looks blunt and indistinct. Even though I am not overweight, the lack of volume and length in my chin makes it look round, flat, and short from the front. Furthermore, even a slight tilt of my head causes the skin under my chin to fold like a double chin. I have tried contouring injections and banding to slim my jawline, but I have come to believe that the fundamental cause is the lack of dimensionality in my bone structure and the chin itself. Bone-shaving surgery is too scary and daunting for me, so I would like to add a subtle accent to just the tip of my chin to create a sharper jawline. Has anyone else experienced improvement in the appearance of a protruding mouth or a more defined V-line after getting chin fillers for a blunt, receding chin like mine?
