Common warts usually require multiple cryotherapy sessions to remove completely, and the exact time of disappearance varies depending on the number of rashes, their size, and the individual’s immune system, so it’s not possible to generalize. Warts are benign skin growths caused by human papillomavirus infection, and can occur on any part of the body, but more on the hands. Liquid nitrogen cryotherapy is a common treatment for this disease, which can destroy the warts, but usually can not be completely cured at one time, and it takes about 1-2 weeks after freezing before the next treatment. The greater the number and extent of warts, the longer the treatment period. In addition, if the individual’s immunity is low, it can also lead to a longer treatment time. The disease is prone to recurrence, so it is recommended to adhere to the treatment as prescribed by the doctor.
