As for that matter, a mole is actually not a problem since it is already there. It imposes no harm unless if it is cancerous or malignant. However, the very reason why people tend to have their moles removed because they think that is an unpleasant sight.
I haven't known any natural remedy for mole removal but of course, as you are aware, the preferred method for physician is the microsurgical shaving excision. It is an out-patient procedure where your mole is first examined under a microscope and predetermined how deeply rooted it is in your skin. Then, an excision will take place. You don't have to worry about the scar for it will leave a pink mark after the procedure and will be healed for 2-3 months.
