I have box scars not deep but wide on my cheekbone. My derm advised to do Radiesse to help elevate the lessons since I have low collagen production along with Fotona's Frac Erbium. My concerns are: 1. is it alright to have injectables if we have slow metabolism? I'm afraid my body could not absorb the filler wholly 2. Does Radiesse & Sculptra not a filler but collagen stimulator? 3. Do we need subcision before any filler for depressed scar? 4. Radiesse or Sculptra?
