I don't find them unattractive, but I don't think they really make people's looks more attractive. They can give a face character-- they make you look like you have a story to tell-- and I certainly don't think anything short of a large disfigurement can really detract from your looks. Scars are a fact of life. I'd rather date a person who isn't afraid to go out and do things that might be dangerous than someone who has managed to keep their skin perfect. When it comes down to it, it's what's inside that counts-- not the scars that litter their body.
