Cryotherapy is a type of physical therapy that uses the extremely low temperature of liquid nitrogen to cause frostbite or even necrosis of the tissues, thus removing the warts. After a single cryotherapy session, blisters and scabs will form on the area, and it takes about a week for the hard scabs to fall off. In terms of the treatment cycle, the removal of a single wart usually requires about 3 to 4 consecutive treatments before the warts can be completely removed. The actual freezing treatment of molluscum contagiosum should be done in the process of skin care, such as keeping the local skin clean and dry, avoiding scratching and stimulation, and giving erythromycin and other anti-infective treatments to the blisters of bacterial infections. As the treatment time is related to the size of the warts, the specific situation needs to be analyzed by the doctor combined with the actual clinical situation, follow the doctor’s prescription treatment, do not self-medication.
