For warts this works very well. It will save you hundreds of dollars vs going to the doctor. The doctor uses liquid nitrogen in what looks like some tin can that looks like you would use it to oil something like an oil can. All that they do is freeze it and charge you a ton. You can freeze off those stubborn warts yourself with this and save a ton. The only problem is that the tube altho small sprays a large area you can't really target the wart without spilling it all over your hand. The solution is to take a drinking straw and insert the tube into the straw press it firmly against the wart and your skin making a seal as much as you can and spray just a little without the air getting to it, it will stay liquid and you will see it bubbling in the straw hold it on as long as you can stand it but, not more than a minute and try to turn it upside down because when you let it off the liquid inside will spill out all over your skin. you should see a white spot on your skin and the wart will be more visible and a brighter white color if you held it on long enough. Then it will hurt for a few days and a water bubble will form as soon as it stops hurting spray it again don't fool around with warts if you do not kill it completely the whole thing will grow back. Even if you think you got it spray it one more time and keep an eye on it just squeeze the area of skin and if you see a white spot hit it again!

The spray is cold. The seller is AWESOME. I had to contact the seller because of a product defect, and they resolved my issue in a very timely manner. I could not have asked for better service. The cold spray itself I'm in the middle of testing it on freezing a couple moles. It takes awhile when the dermo does it so I'm guessing that it will take while at home, as many other reviewers have noted. I have been using the ear cups that a few have mentioned to prevent overspray. The cold liquid does fill up the cup if you aren't careful and your fingers holding the cup may get mighty cold, beware. Go slow.

Received the spray without a nozzle tube. Pretty hard to use this without one. I searched around and found one that would fit from a chain line can. Cleaned up the tube and have had to use it. For those that say to spray in a cup and use a Q-tip it is impossible. Tried that and this stuff evaporates before you can get the Q-tip to the cup.

I started using this a few days ago, it's working great. Every time I went I to the Dermatologist he would take off one or two, but I had many of the same kind that I wanted removed. I walked in and asked one Dermatologist how much to remove 15 or so, $450.00 was the out of pocket price, I left, when you want all of those removed, it's considered "cosmetic". I read all of the reviews, tested it on a piece of paper to see how big the area would be with the small straw in there. The area is about 1 1/2 inches wide, too wide for tiny little skin tags. I tried a couple different things and settled on taking some of the cotton off a cotton swab, to make it smaller, freezing the cotton tip and quickly putting it on the skin tag. I lay the q-tip on a piece of Styrofoam so that it stays cold. Make sure the skin tag turns white, it will sting a bit. If you want to get an idea about how the doctor does it, there is a demonstration with liquid nitrogen on youtube. He turns them white and then goes back and does it again. So I did that too. This is less cold than liquid nitrogen, so the next day I did it again for good measure. It takes a few days to heal over. But this method keep the area nice an small, without damaging good skin I'm looking forward to being rid of these.

This is how I use it and it works great this way. I use Qtips. I DO NOT use the straw that comes with it. I tip the can down and BARELY squeeze the trigger and the liquid DRIPS out, NO SPRAY. The drips soak the Qtip and then I apply to the area I want treated. A few days later I remove the tissue I wanted removed. NO SPRAY, just use the drops to soak the QTip. The can will last a long time using this method.
