How does cryotherapy work?

Cryotherapy is very quick and straightforward procedure performed as an outpatient treatment and involves liquid nitrogen applied to the skin with a spray gun or cotton bud.  The procedure is very quick, depending on the thickness and size of the lesion. The frozen skin becomes white and takes one to two minutes to thaw to normal skin temperature - your doctor may suggest this is repeated once the skin has thawed out.  Over the days following treatment, a scab will form, this will take a couple of weeks to fall off – this process cannot be hurried.  Depending on the response of the tissue treated, follow up sessions may be required.
