Beyond excessive itching with Fraxel Restore. Any suggestions?

I had fraxel restore on areas from top of my thigh, over hip bone to back of my small love handles. I had one treatment which so far has improved them nicely, but the itching was so major and lasted up to five days of insane intensity, then another five of so so and then another five of mild. I have MTHFR genetic mutation that is severe and it affects histamines, disabling repression. Any suggestions on how to proceed for next treatment? This was beyond annoying to practically unlivable.
