I brought it to use to get rid of some skin tags that I had on my neck area. It is easy to use it stings for a few secs there is nothing to it. You must use it in a well ventilated area. The instructions are easy to read and understand. It worked for me but I had to do 2 applications on a few skin tags I spaced them apart of course after a few weeks they fell off and were gone. I was so pleased with it. The only thing is I wish they gave you more foam tip applicators because once you use it once you have to discard it. It comes with 8 applicators. I recommend it it really does work. It is pricey but worth it because it works. Before using or buying please read box and instructions.
