Facial Scars from Laser Hair Removal and Fraxel

I had several LightSheer treatments in the fall of 2003 to 2004 spring. This treatment worked fine but left hyperpigmentation and even caused some burns but they healed without scarring. In the summer of 2007, I had 1 Fraxel Laser treatment. It did not go well. I had 1 Yag laser hair removal treatment about 4 months later that fall. I have brown skin (Indian) so I had low settings. The Yag laser hair removal was great, but I began to notice depressions in my skin. They were everywhere. I've noticed my left side cheek is riddled with small follicle-sized holes. I can tell that my skin is of uneven depth on this side. The difference between my left and right cheek is astonishing. Yet, I had both laser treatments on both sides. The technician sprayed cool mist on my face between passes. Is this the cause, and is it irreversible? Can dermaroller or needling help?
