Stuff works. I got rid of two stubborn warts that I'd had for years. Using the attached straw, I sprayed product in a plastic cup. Careful! This stuff can be extremely dangerous! Do not let kids play with it and spray away from your body/face.
Quickly, I soaked up the liquid with a Q-Tip and applied to the wart for about 30 seconds. I did that three times in a row (total 90 seconds). The wart will look white then turn pink. I repeated the process every other day two more times (total of 3 sessions). For the larger wart on my knee, a filed off the top layer of the wart so that it was a bit raw before beginning. After treatment, a blister formed on my knuckle wart. A week later the blister healed and there was healthy skin underneath. My knee's wart turned black (I'm Caucasian). After a week, I peeled off the black skin and there was healthy skin underneath. I'm so thrilled that this works. Talk about a money saver. The first time you try this, I recommend having a partner help you, as you'll probably be a little nervous. My husband sprayed the spray and swabbed the Qtip, then handed it to me so I could apply it to my own wart. This worked well. BTW, this treatment is not pain free. It does sting both during treatment and for a few hours after. I suggest doing it right before bed, so you can fall asleep afterward. But it's not that bad. I'm by no means tough, and I can handle it.

Worked great! Used a little plastic ear probe funnel thingy to isolate the wart and freeze the sucker! Did the trick with one round of freezing. Hit it really good. Probably three times for five seconds ea one night. Be careful tho - that condensate is COLD! Even with the plastic funnel, the freezing liquid leaked out onto my surrounding skin and "burned" it a bit. a patch was pink for a week after. It stung a bit but nothing I couldn't handle.

This stuff will definitely freeze the crap out of warts. A lot like liquid nitrogen but a lot less control than the doctor. But a lot cheaper too. Use at your own risk, you're not supposed to do this. Officially if you use the product incorrectly don't blame anyone if you burn your skin. You can give yourself burns but honestly I've had this planters wart so long if this doesn't work it's surgery time so I'll take the chance.

Buy Q-tips and rubber gloves. KEEP AWAY FROM CHILDREN. I'm so glad I didn't apply this directly to my skin. A jet stream of freezing came out of this can, like I couldn't believe. I would suggest buying Q-tips and rubber gloves to apply. Freeze the Q-tip and then quickly apply to area. Otherwise you could hit more than you bargained for. This works, boy does it work. I read somewhere about a dollar sized freezer burn. I can believe it.

I had a huge sun spot on my cheek & several small ones as well. Sprayed product into a plastic cup, dipped cotton swab & applied several times. My face was red & burning after. Over the next couple of days the spots got darker, then peeled off. I had tried everything on those spots & am excited something finally worked :)
