At Petersfield Chiropody we use cryotherapy to treat verrucas and warts. Cryotherapy involves applying small amounts of super cooled liquid nitrogen to the unwanted lesions, freezing them to -197 degrees for a few seconds. With success rates of around 70%, cryotherapy is an effective treatment for removing warts and verrucas of up to 7mm diameter.
Although not a guaranteed treatment, most people find cryotherapy to be the most effective and the least time consuming method of treatment.
