You’re basically creating frostbite in the wart and in the immediate vicinity.
As cells freeze, the ice crystals rupture the cell wall, killing the cells.
On the 0.5cm x 0.5cm area of the wart, these cells die, a blister is formed and your body heals.
Some warts will reappear presumably because the wart was left with a viable “root” that wasn’t damaged.
Repeated treatments may be necessary to kill off the wartogenic cells.
