No scars, no. It was like they took a little divot out, so the "wound" was kind of concave. They put band aids on them. And it was an in-office procedure.
My insurance must have paid for it, because I don't remember how much it cost. I know they should be removed (and biopsied) if any have changed shape or color at all, so remember to mention that to the doctor. Call a reputable dermatologist in your area and ask for a rough idea of how much it would be and if your insurance will cover it ... they will know after they see you.
