I see you've already had a lot of suggestions, I figure I'll go ahead and throw mine out there. I was given this salve a few years ago by a friend. It works great. I'm currently using it on a burn scar, but it is a new one. It is healing nicely and fading quickly.
I used it on a scar a few years ago. My skin had a pretty substantial dent in it and the scar was about two inches long. The skin is now flat, the dent is gone and I have to look very closely to find the faint scar. The scar was a about six months old when I started using it.
I use it as often as I remember to rub some on. Especially at night before bed.
A lady in Tennessee makes it. Here's a link to it
