Bazuka Sub-Zero Bazuka Sub-Zero is a 'freezing' wart removal device based on the cryotherapy method used by doctors. Bazuka Sub-Zero is an effective freezing device for removing common warts & verrucas in the convenience of your own home. It works by quickly freezing the wart or verruca to its core, causing the formation of a blister underneath the wart or verruca which helps it loosen & to fall off, often within a couple of weeks or so of freezing, revealing normal healthy skin underneath. It is important that you use Bazuka Sub-Zero cautiously, applying it with steady gentle pressure only to the wart or verruca & only for very short periods as directed in the patient information leaflet. Ingredients The freezing agent is a liquified mixture of dimethyl ether, propane & isobutane. The pack contains a pressurised aerosol can containing 50ml of the freezing agent, a dome shaped safety cap, 12 foam activators & an instruction leaflet Directions Follow the directions given in the patient information leaflet.
