I had my first CO2 Fractionated laser treatment on July 31 2013. My doctor says I need another 2 treatments for my deep acne scars. I improved 20% after my first treatment. I am happy with the results. I do not know if it is time for my second treatment. My doctor says it is all right to do that now, but I am afraid to get deeper scars if it is done too soon. Thank you very much for your answer.
