Frozen moles usually fall off in 1~3 weeks, but the exact time of removal varies depending on the size of the mole and the postoperative care. Mole removal by freezing refers to the use of cryotherapy to remove moles. The principle is to use liquid nitrogen to freeze the local area and cause cell necrosis in the affected area through low temperature, so as to achieve the purpose of removing moles. Usually, there is a process of scabbing and scab removal in cryotherapy, and it usually takes 1~3 weeks for the scabs to fall off. If the area of the body mole is larger or deeper, its shedding time may increase. If the postoperative care is not proper, such as the wound touching water, mechanical friction and other local infections, it may lead to the prolongation of its shedding time. Therefore, the exact shedding time of cryo-mole removal cannot be determined. If you need to take cryotherapy to get rid of moles, it is recommended to go to a regular hospital to consult a specialist and learn about the relevant matters.
