Cryosurgery

Freezing treatment with liquid nitrogen for certain warts and benign skin lesions.

What it is used for

Patients with lesions the dermatologist has confirmed as suitable for freezing.

Liquid nitrogen is applied precisely to the lesion, freezing the abnormal tissue so that it separates as the skin heals.

A stinging cold sensation for a short time. Usually no anaesthetic is needed.

Redness, swelling or a blister may form and settle over days. Temporary lightening or darkening of the skin can occur.

The number of sessions, if more than one is needed, is decided at consultation based on your condition and how your skin responds.

Warts can recur, and repeat treatment may be needed.
