Is it normal to have burn marks so long after laser lipo?

I received lipo a few months ago. I sustained one pretty large burn, and then the smaller incisions throughout are still very much evident 3 months post lipo. I have gone for follow up regarding this and I am being told that they should fade away, but I don't really see much improvement and I'm becoming concerned. Add insult to injury I'm also not happy with how the lipo itself turned out. Is it normal to have marks from the incisions so many months out? Do they fade or am I scarred for life?
