Laser spot removal burn isn't healing. (photo)

I had a treatment 2 months ago to remove a childhood scar on my cheek. The technician used three different kinds of laser. I think one of them was fraxel. He also made a few injections in the scar. My skin was inflamed and had a burn sensation for a day or so after the operation. The newly generated skin emerged after 10 days, however, it was still quite red and remains so almost two months later. Is this normal? How long does it take to fully heal?
