What is the Risk of "Orange Peel Skin" Texture After a Fraxel Laser Treatment?

I am scheduled to have Fraxel laser treatment in the next week. My skin has always been fairly smooth but as I've gotten older, I've noticed my pores are larger and my skin less smooth. My dermatologist feels I can get by with one treatment to get the results I am looking for, which is to smooth out the fine lines and the texture of my skin. I've read a few people who say they are really regretting that they ever did the procedure. How often do you see the orange peel skin as a bad result?
