Should I wait between TCA Cross/Peel, Collagen Stimulator + Subcision & Fractional Erbium laser treatments? (Photo)

1. Should I wait between these treatments? if yes for how long and what treatment(s) would come first? If no, what'd be the sequence within that 1 session ie. TCA Cross - collagen stimulator - subcision (if needed) - Erbium. Also, is it OK to poke frosted area of TCA Cross with needle & subcision?     2. Radiesse or Sculptra , scars located on the apple of the cheek to side temple?    3. Does collagen stimulator yield a better outcome combined with subcision (especially for my scars)?
