Iso- Facial balancing. Chin filler / implant? Masseter botox? (Photo)

I feel my upper and lower face are not in balance with my chin being recessed unless I force my lower jaw foward when smiling. I also have additional muscle / tissue (masseter?) that I feel adds to the imbalance when I teeth smile. Would chin filler / implant help to balance my face without making it appear too long when I smile? Would masseter botox help relax the additional tissue for improved facial contouring?
