Can dermal grafting improve rolling acne scars?

I have two deep large rolling type depressed acne scars on my right cheek. The scars seem somewhat pliable or distentable. However, they must be somewhat tethered down because I've had Restylane and Perlane in the past that that simply donuted around the scars (even though subcision was done before each injection). So, I'm thinking dermal grafts or even a synthetic graft could be placed more precisely.

So far, I have only been able to find two doctors who offer this procedure. Any advice? Any suggestions in helping me find someone who does dermal grafting?
