Is it safe for me to remove the mole using the pen? (Photo)

Benign vs. malignant moles should be examined by an expert to determine risk and the need for a biopsy. Non-surgical options exist to help reduce scarring. Minimizing scar tissue is paramount and can be achieved by employing laser treatments and post-treatment scar therapy.

The best way to remove a mole is with a close shave procedure. This will shave it flat and leave as minimal a mark behind as possible, assuming you follow good post care. I don't know the pen you are referring to - perhaps it's something only available in Germany? "This answer has been solicited without seeing this patient and
