My sister had two moles on her face removed about 15 years ago... she still has small scars, but that's just because our skin scars very easily. This won't help you any because I doubt you'll be able to find a reliable ancient Chinese medicine practitioner, but a family friend had one removed this way once - the guy just dropped some unidentifiable liquid on it, waited a minute or so, dropped some other liquid on it and then wiped it away with a cloth a few seconds later. Or something like that.
