You need subcision and TCA. Multiple sessions for multiple years.Focus on blurring the scar edges rather than filling the pits outright. Once the edges are smoothed out sufficiently, use dermal fillersto elevate the pit. It is possible to do TCA at home if money is an issue. You will need to find derm or plastic for subcision though. Lastly, stay away from those doctors that recommend laser. You can achiever nearly the same from TCA. Good luck.
