Over the Counter Wart Treatment Not as Cold as Mine

OK. There’s cold. Then there’s really cold. Growing up in Providence, RI, I can remember waiting for the school bus on frigid January mornings. Some days, it was zero degrees. I can tell you, when it’s zero degrees out, a 30 degree day feels balmy.

It’s the difference between cold and really cold that matters when it comes to treating warts.

A recent study in the Journal of American Association of Dermatology explored the difference between over the counter wart freezer and the one that we use in dermatology clinics. They found that the coldest the over the counter product could achieve was -4° F (-20º Celsius). Pretty cold.

But the liquid nitrogen used in dermatology clinic was colder than -148º F (-100º Celsius), the lowest the sensor could measure — much colder than the over the counter version!

I am sure your wart will be able to tell you the difference.
