Update on the itworkspaste that I bought and tried. The mole hasn't come back, so it definitely worked in that one 20 minutes as they said it would. My friend who had some skin tags on her neck used it too and they zapped all of them. I had a pink mark for a little bit, but they now have an itworks scar gel that I apply to it. It has helped so that I have hardly anything pink anymore. I would do it all over again, and for those of you who are scared to try it because of the sting, it only stung for a few seconds with me.
