what can i do to lighten my skin grafts? (Photo)

In 04' I was in a house fire. 33% of my body was 3rd degree. Hands, legs ,back chest, arms and face. The discolor and thickness of my scars on my face, is what im most concerned with. The rest I am ok with? And I am not trying to sound superficial (hehe). Its just every where I go, people stare. The looks I get make it very uncomfortable for me. So, what can I do for It? Anything?. I truly can't afford to do probably what I need. But advice to go in a direction would be much appreciated.
