The profractional laser really did very little for my acne scars. I had two treatments and saw very little if any improvement in the scars. I was told 3 to 4 treatments should improve the scars.
After the two treatments I already had, I doubt I would be blown away by two more. The pain of the procedure was very little if any. The downtime for this procedure was 3 to 4 days. Which is too much for a series of 3 to 4 treatments. I also don't think the laser specialist is all that experienced for the profractional laser in the treatment of Acne Scars.
The person who uses the laser is just as important if not more than the type of laser itself. I would recommend a fractional CO2 laser over an erbium laser.
