Best Mole Removal Technique?

Tags:man mole scar excision burn removal

I have a small flat brown mole on my face that I want to get removed. I had one other small mole removed 10 years ago and I believe it was removed by a tool that burned it off (maybe radio frequency?). The mole I had removed 10 years ago healed without any scar. It looks like I never had it. Is burning still the best technique for flat moles?
