If you have described it as deep pitted scars, I would suggest that you speak to your doctor first. It is my experience that many patients have pre-formed notions of the correct treatments for their type of scars.. which usually isn't that correct.
I would probably consider TCA Cross for the deep pitted scars instead. Any photos would be useful!
But that said, pertaining to your question, I echo Dr Boey's idea that subcision with fillers improves the overall appearance by reducing re-attachment rates AND the biostimulatory effects would help plump up the atrophic scarred areas.
Generally my patients have been satisfied with their subcision results with the use of fillers.
So hope it works for you too.
