The Cryotherapy is the well-known treatment used by physicians for skin troubles. This application involves the extremely cold temperature more than the normal so as to smash the damaged cells, Liquid nitrogen used as cryogen is applied on the skin part which needs to be treated with the help of cotton swabs. This mechanism of cold exposure works promptly as living tissues either healthy or disease cannot stand the cold temperature and hence get scattered clearing the area of skin.
The Cryotherapy is categorised into three phases:
Heat Transfer: On the outer region of skin liquid nitrogen directly transfers heat, and for inner tissues, an incision is made for the heat transfer.
Cell Injury: After the heat provided to the cells, the frozen damage can be seen as cell injury.
Inflammation: The last is the blister formation
Results: The pain moles and other skin infections get suppressed and the white blood cells wash out the dead tissues
