For warts, freezing and laser treatment are both available options, but there are some differences in the specific treatment process and results. Freezing is the use of liquid nitrogen at -190°C to act directly on the wart tissue, causing necrosis and blistering of the wart, which in turn removes the wart. Small warts can be treated in 1 session, while large warts may require 2-3 sessions or more, and the interval between treatments is about 20 days. The laser burns off the wart directly, but the burns are traumatic and cannot be exposed to water, and the laser treatment can easily leave scars of varying degrees. After cryotherapy, small warts can be restored to completely normal skin, and large warts can be restored relatively better than laser treatment, but the number of freezing treatments and blisters will be more frequent and the treatment period is longer.
