What could i use to prevent burns turning into scars?

i burnt my face and chest with hot grease two weeks ago..


i used aloe vera gel and all it did was cool the burn and ease the pain..


i used burn ointment and spray and they made it fade a little bit..


i dont want scars on me forever what could i use and where can i find it???What could i use to prevent burns turning into scars?
well i have heard that if you just get a vitamin E soft gel and split it into and get the liquid out and just put it on your scar it helps to fade it. Hope this helps.
