Fractional co2 for atrophic scarring?

I had a disfigured atrophic scar in my face which was very visible. I have done 3 picosure then 2 fco2(spot tx) and i am scheduled for 2 more. I can say there in some improvement but when shall i really see full results? My first laser(pico) was last august and as of today ive finished 3 pico and 2 fco2(spot tx), future fco2 will be scheduled 2 weeks from now and then january 2nd week.
