DermaTend
Had a few moles on my body. Worse one was in front of my ear, just under my hair. Nearly every time I went for a haircut they'd catch it on the clippers (even after warning them). Doctor quoted $400 to remove it.
A friend recommended DermaTend. At first I thought it looked like a scam.
DermaTend cost less than $100 and didn't even leave a scar. Doctor wanted to cut it out. I also removed three other moles on my face and neck with the same portion.
My sister also used it on her dog's ear to remove skin-tags. Worked great.
