Hi Cedar!
I too believe that, unfortunately, no cream will have enough of an impact to really reduce scars, although they can be very beneficial your skin.
What I would advice you to look for is a clinic or health center in your area that practices Endermology; a type of in-depth tissue massage that improves the structure of the skin. Two years ago, I had a scarred, blotchy, red-patched forehead and thought I had to either have laser therapy or live with it. But after undegoing endermology treatments for a few months, I now have normal skin!
I'm European, so I don't know about the situation in the US, but for me the treatment was covered, and even if it hadn't been, it would have been cheap enough to pay for myself (being a student) and absolutely worth it.
Either way, I can totally relate to the frustrations of having problematic skin, and I wish you lots of luck with finding a solution!
