After Care of Mole Removal Above Lip?

I had a mole removed above my lip today. The physician only said to use Vaseline and keep covered with a bandage. Is there anything else I can do to prevent a big scar. It was cut off. I seen a plastic surgeon a couple month back that said my skin heals fast and clean. He based that on some marks I already had. But I didn't remove it with him because he was charging over $700. I read a lot of comments on people using miracle skin salve. I wanted to know if that's something I can use.
