I have a small mole under my right eye and I'd like to get rid of it. Last year I went to a doctor (cosmetics) and he underwent the removal by using plasma laser. Recently, I see some videos about mole removal pen. My questions are: 1. Is it safe for me to remove the mole using the pen? 2. If I remove the mole by using this pen, is there any guarantee that the mole won't grow back? Thanks in advance
