Could the co2 fractional laser resurfacing really work for acne scars?

Yes helpful: Series of deep fractional laser treatments may help acne scars, but unlikely to remove all. Depending on shape and depth of scars influences result. Example, 'ice pick' type scars hard to remove, 'crater-like' poc marks do better to smooth scar margins from nearby skin. Also may need mechanical dermabrasion which improves surface smoothness.

Yes: Fractional lasers can do a nice job of improving acne scars. I generally treat bad acne scars with a combination treatment, including laser, PRP and sometimes subcision (for the deep ice picks) or fillers/fat transfer. For scarring that is not so severe I will generally start with a course of Laser Genesis (about 5-6 treatments).
