Hi, I am a patient with acne scars. During the last 20 years I have tried all sort of treatments, subcisions, peeling (gluycolic, jessner, etc), and more than 10 sessions of different C02 lasers. My skin has improved a lot with the various treatments but there is still plenty of room for improvement. My problem is that the last 5 C02 sessions are not showing big results apart from giving a nice colour to the skin. What to do next to continue improving my acne scars? I was thinking of Fenol peel
