A mole in this area is tricky to remove. One must be careful about the junction between red part of the lip and the regular skin. That being said there are ways to minimize scarring and get good results. You should see a board certified plastic surgeon. He or She would be able to advise you on the best technique for this. I have done this many times and there is no best way since each situation is unique and has to be tailored for each patient individually.
