Hello, Doctor: I just finished 1 treatment for fraxel 1550 on 70mj and 23% 2 days ago to treat my acne scar and i am going to do fraxel dual after 4 weeks. I know that the highest setting for 1927 is 20mj and 30%. My question is that is it ok to put 1550 setting on 70mj, 23%, 4 passes and 1927 on 20mj, 30%, 4 passes at same time for my fraxel dual treatment for maximum result? If not, what is the typical setting then? Kind Regards Tom
