I had severe atrophic acne scars on my cheeks. two years ago i had bellafill filler for my scars and it filled them and the results are great. Now i am considering doing subcision for my cheeks to see if i can get further improvement. I have boxcar and rolling scars. My question is that if i do subcision will it affect the placement of the PMMA beads that are left from bellafill? Will subcision move the PMMA that is meshed in? I dont want the PMMA to be displaced or moved around
