Safe to combine CO2 laser with TCA CROSS treatments?

In my opinion, combining TCA cross and CO2 is acceptable. The TCA cross must be performed prior to CO2 laser. However, in my experience multiple sessions of TCA cross are usually necessary to get scars to lift. I would recommend getting the acne scars prepared and level prior to performing the CO2. Find an acne scar expert. Ask to see photos. Hope this helps . Good luck.
