A dermatologist told me that it may cause blisters.
Nitrogen must be cooled to a very low temperature to become liquid nitrogen. At room temperature, liquid nitrogen will change from the liquid phase to the gas phase. Therefore, if the skin is treated with liquid nitrogen, the liquid nitrogen will almost instantly become a gas and evaporate away from the skin. It is impossible to "leave" it on the skin, as this reaction is almost instantaneous and no liquid nitrogen is left behind.
Liquid nitrogen.
No. Nitrogen does not irritate skin. But liquid nitrogen is extremely cold, and it can damage and kill skin (and other) tissue. It is a bad idea to allow your skin to come into contact with liquid nitrogen. Note: Some warts are "frozen" in an effort to remove them. In a clinical setting, liquid nitrogen is sometimes used to super-cool an instrument so the wart can be frozen. But this is a medical procedure and is done by professionals. Liquid nitrogen is not something that should be looked upon as a "toy" or "recreational plaything" by anyone.
Yes. Yes.
yes.it destroys the skin.

You are touching nitrogen right now- almost 80% of the air touching you is nitrogen gas. Quite safe. LIQUID nitrogen is another matter- it is an extremely cold liquid that will freeze your skin on contact.
Liquid nitrogen, which is very cold, is often used to freeze warts and skin cancers quickly so that they can be safely removed from the skin. This process is sometimes loosely called "burning off" the skin blemishes so treated, but it is not burning in the chemical sense. Any other cold liquid that does not adversely react with skin could be used as well, but liquid nitrogen is usually cheaper than any other available liquid. The chemical properties of nitrogen, other than non-reactivity, have nothing to do with this use of the element.
It's not bad for you as it is what they use to freeze off warts from your skin.
For a short time nothing; later the skin is irritated and then freeze the hand.
Doctors use liquid nitrogen to destroy common skin lesions such as warts and actinic keratoses, among others. It causes a small area of frost bite around and under the lesion, effectively killing it.
When handling liquid nitrogen, it is important to follow proper safety precautions. Wear appropriate personal protective equipment such as gloves, goggles, and a lab coat to protect skin and eyes from contact. Handle liquid nitrogen with insulated gloves or tongs to avoid direct contact, and ensure adequate ventilation in the working area to prevent build-up of nitrogen gas. Also, be aware of the risks associated with the extreme cold temperatures and rapid evaporation of liquid nitrogen.
