Hyaluronidase nervousness. Any suggestions?

Hi, I had restyle filled in my marionette, laugh lines and tear troughs like 2 months ago and ever since I have only hated it. It had given me the appearance of having jowls and a fat lower face with no cheek bones which is the opossite of my desired outcome. I just want to know if hylase is a good idea and how the doctor knows where to inject it. I am paranoid of just relying on his memory.
