i had a skin tag on my armpit for years. since it always got in the way of shaving my armpit, i had it removed when i was 22. it was done by cryosurgery, where my primary doc used a q-tip soaked in liquid nitrogen to put onto the skin tag. it burns a little at first. in a couple of days, the skin tag fell off. mesto presto! it was an easy removal of the skin tag. i'm sure the freeze-off you buy at the store would work as well (it might be a bit expensive).
