I have done CO2RE about 2 years ago (cannot recall the date), and I have Fitzpatrick III skin. All I can say, after 2 months post-treatment, there was about <10% improvement. It may just be my skin not reacting well to the treatment, but expect 1 week of down time, at least, and the treatment is quite painful despite getting numbing cream and injections to calm my nerves.

I had better results from subablative RF, and healed from it much faster too. Either way, that's my 2 cents.
