Scars from corner lip lift?

I am seriously considering this. I do not have a lot of dental show and don't like my smile. After meeting with a couple surgeons, I have been repeatedly told the scars are basically undetectable. But what does this mean? Does anyone have any pictures of the scars as they will look? I was told they would be treated with a laser. I would be very grateful for any information or pictures! Thank you so much.
