3rd degree burn scar - can this be improved? (photos)

Hi I was wondering if I could have an opinion on whether improvements could be made to the scarring shown in the photos attached. These are burn scars that I have lived with since the age of 2 and, after reading about the laser treatment provided at your clinic, I would like to get an opinion on any potential enhancements to the scarring on my arm and leg. My objective goal is to have the scarring minimised whilst feeling softer/smoother and looking in better shape.
