Those freeze solutions you buy at the drugstore are mostly intended for warts.

A mole, or a nevus, as it's properly called, needs to be taken off by a doctor so he/she can send it for pathological evaluation. They can excise a mole by essentially shaving it off, or remove it surgically with some surrounding tissue if it looks suspicious. Or freeze or burn it off, but their cryo-procedure (freezing) is different from that Freezone wart remover. That's basically an acid that burns warts off. It doesn't leave a bad scar at all. It'll be pink for a time and then fade to white. And it's not a painful procedure.

I had a little brown mole removed from my neck. My husband loved it. He called it a love spot. But I hated it. It itched and I sometimes scraped it with the comb when my hair was longer. Now you can't even tell anything was ever there. It was very small. I'm not a very moley person. But I'm glad I had that one taken off.
