I had 3 picosure focus spaced 2-3weeks apart for atrophic scarring. It was for the whole face, very shallow pitted scars and 1 huge pitted scar which was given many passes. Now, i am looking for a more affordable tx but my doctor has limited lasers. Went to anoder derm and she is going to give me a fractional co2, 4 weeks after my last pico tx. Will 1 fractional co2 yeild results soon since i already had 3 pico tx already? How soon will i notice results?
