I second trying kelocote. I've been using it and also massaging the scars with Vaseline since surgery a year ago. My scars are still slightly reddish pink around the edges but have mostly faded to white and are pretty thin.
I was reading up on scar care before surgery and found that it's recommended to massage the scars through the healing process. I really think it made a difference, both in the thinness and flatness of the scars. Don't get me wrong, they're still visible, but definitely not bad.
