Very simple procedure and took only a few seconds and woala, it was gone. Virtually painless other than the dry ice feels like it's freezing you for a brief few seconds. But the plantars wart was gone instantaneously.
She had to keep it bandaged for a few days, but it did not cause her any pain. (she was high school aged).
This procedure sounds much better than having it cut out. Probably been 10 yrs ago and it has never returned.
