Lenusik,
Oh my gosh, I don't know how I missed the story about your crash. I went back and read about it since I was curious about your scars.

Here's a list of what I've used for scars:

Neosporin Scar Solution or any version of silicone sheets. The pressure helps prevent scarring. That's why burn victims wear pressure suits to limit scarring.

Mederma Cream

Vitamin E oil capsules. Cut them open and massage into skin. I also have a theory about massaging. I think it increases blood circulation that could quicken healing.
