Operation method of liquid nitrogen cryotherapy machine
Mar 13, 2021| According to the size of the lesion, choose an appropriate freezing head and screw it on the infusion tube of the liquid nitrogen treatment instrument to cool down for about 2 minutes.
Use the freezing head to freeze the lesion until the skin becomes frosty white. About 2-3 seconds. The abnormal cells in the area freeze to death, scab, and finally fall off and replace them with new normal skin cells.
If there are no frozen lesions after the treatment, the skin can be frozen again after the skin has completely recovered.
