For scars – a chemical burn scar or other scars, would a peel or CO2 laser be best?
For scar tissue, there is a lot of data now showing that fractional CO2 lasers and even some fractional erbium lasers consistently get the best results. Find an expert laser physician, and the DEKA DOT CO2 and the Cynosure Affirm CO2 are particularly customizable for scar tissue. Often 3-8 treatments are needed depending on the area where the scar is and how large it is. It’s important though to not expect it to be “perfect,” just much less visible.

In my opinion, if you have true scars (not just uneven pigment), TCA peels are ineffective and often dangerous. Peels don’t penetrate evenly into scar tissue and it’s very difficult to calibrate the depth exactly.
Hope this helps, Dr. I
