Cryotherapy or Cryosurgery for skin lesions Do-it-yourself
Here is another trick to get rid of small skin lesions or warts..Its almost as good as the liquid nitrogen you get in the doctors office and a whole lot cheaper..
Liquid Nitrogen~ -320 F
Dry Ice~ -110F
liquid from dust remover cans -25 to -160F Boy this stuff sure feel like it is under -100 I will tell you...
This works a whole lot better than dry ice...
The only thing I have to add to this link is do not spray the liguid from the can on to the skin..It freezes to much heathy skin...Spray the liguid into something then use a Q-tip to put the liquid on to only the problem spot..
Be warned this is not as good as liquid nitrogen but still very very strong..So if you use this please do a few test spots first...
This seem to work well for that small nasty skin lesion that just does not seem to go away(I have had a few on my leg)...I do not think it would be the best idea to use this on your face though..
Any ways here is the link...

Also use the dust cleaner that uses tetrafluoroethane other kinds use difluoroethane and do not work worth a flip...
Safety
Tetrafluoroethane itself has an LC50 (lethal concentration for 50% of subjects) in rats of 1,500 g/m³, making it relatively non-toxic. However, its gaseous form is denser than air, and will displace air in the lungs. This can result in asphyxiation if excessively inhaled.
Aerosol cans containing tetrafluoroethane, when inverted, become effective freeze sprays. Under pressure, tetrafluoroethane is compressed into a liquid, which upon vaporization absorbs a significant amount of thermal energy. As a result, it will greatly lower the temperature of any object it contacts as it evaporates. This can result in frostbite when contacting skin.......Yea Just what we want lol.....
This is much stronger than the wart freeze you can buy from the drug store...Some times the duster with the tetrafluoroethane can be hard to find...You can find this online at Office Depot...

very interesting post. I have often wondered if using dust off would be like liquid nitrogen because I have used it for dusting and noticed if you turn the can upside down, it sprays a very, very cold liquid. The liquid nitrogen the derm uses comes in a spray can with an extender just like the Dust off.
I'd be interested in hearing from someone adventurous enough who has tried it before I accidentally freeze off a limb or something. |

If anyone tries the Dust Off, my morbid curiosity would like to hear about it too, but I hope nobody does. I'm weirded out by the thought of spraying something like that on your face, or on any part of your body for that matter.
Remember when you pay the cost of liquid nitrogen treatment by a dermatologist, you aren't paying for the contents of the spray can; you are paying for the doctor's expertise, and that's worth a lot! I believe in natural, alternative, non-invasive methods of health care as much as anyone, and I wouldn't have expected to be defending the medical “establishment,” but unless you are really strapped and don't have insurance, I don't think it makes sense to use something like this by yourself when you can have it done by a professional. |

If anyone has a serious medical condition please please see a doctor...
A aerosol duster can in no shape or form be a substitute for a doctor...
I hope people understand that there is a big difference between a small skin lesion and much more serious skin conditions such as melanoma...
I posted this because I believe in freedom of information..If people do not have the information then they do not have the freedom of choice..
Freezing a skin problem would not be my first second third or forth things to try..The Sunspot cream,Orange oil,Eggplant,Aloe Vera ect are alll much better treatments...But some one out there some where may need this information for what ever reason...
Before I have had liquid nitrogen treatment from a dermatologist.I have tried freezing a problem spot with dry ice.I have tried the wart freeze from the drug store and I have tried the dusting cleaner..
The liquid nitrogen treatment from a dermatologist will give you the best skin freeze that is for sure..The cleaning duster will give you about 70-75% as good of a skin freeze as the liquid nitrogen..The dry ice will for the most part just make a big frozen swollen mess of things unless you only use a tiny bit...The aerosol wart freeze from the drug store can work but its really kind of wimpy stuff...
If your a first time skin problem person please do not try this see a doctor..
People like me who have been through the dermatologist merry-go-round have to keep all possible treatment options open....
