What layer of the skin/tissue is best to place restylane/juvederm to avoid the filler from moving around?

I wanted to add more volume to my chin so I have been injected with voluma, but I experience that the filler wont stay where it was injected so it has found its way to under my chin and not in the 45 degree angle as it was placed in. Would this be avoided if I got a filler not so deep as the voluma is set? Im just thinking that if I had a filler injected ringt under the skin surface some place it would have stayed in place and not moved like the voluma? My goal is volume in the 45 degree angle.
