I don't know if you've ever heard of Scar So Soft, all the sites i know of look lame and stuff, but I bought it anyway, i get keloid scars...hope you don't...i guess at some point i popped a pimple or something, and when it scarred, it just kept going, resulting in a ugly brown bump, and you can't do anything about it...so i researched and all...its all i could find...and it works...so maybe you can try it out...
