Am I a candidate for filler in the cheek bone area? (photos)

I would love to put fillers on my cheekbones (1 ml total – 0,5 ml to each side) – only on cheekbones, not on cheeks, but I am concerned about the area on the cheek that I would describe as thick tissue (not hard as bone, more kind of soft). Most of it is located on the cheek, but part of it is high where the cheekbone area is. I have been aware of it for the last 16 years (it does not grow). Do you know if this is something natural and common and would it be safe to put fillers on my cheekbones?
