Another Full Face or Spot Treatment Needed to Get Total FX Results?

I had the Total FX done for pigmentation and ice pick scars (from electrolysis). I thought that after having the Deep FX done, the scabbing would be more severe than with the Active FX part of it. I had nothing like that. It was all uniform and red, so I don't even know if he did the Deep FX on me or where.

I was told that the brown spot on my cheek would be gone after the skin peeled. The skin has now peeled (day 5) and the spot is a lot lighter, but still visible.

At this point, how long should I wait before I get another treatment? Is it possible to have just touch-ups, or does the whole face need to be re-treated?
