Bazuka Sub-Zero starts working from the first application and works by freezing warts and verrucas to the core. Based on the cryotherapy method used by doctors, it's fast to use, and effective.Watch our handy guide
Soak the verruca or wart in warm water for a few minutes.
Dry using your own towel to avoid spreading infection. After drying, gently file with an emery board or pumice stone.
Assemble the applicator so it’s ready for freezing, then ‘charge’ the device by pressing down on the safety cap for 3 seconds.
Immediately after charging, apply Bazuka Sub-Zero directly to the verruca or wart with a constant, light pressure for the time specified in the table below.
For those with delicate skin, a shorter contact time of half the recommended number of seconds may be advisable.
|Lesion Diameter||WART Contact Time|
(less than 2.5mm)
(from 2.5mm to 5mm)
(larger than 5mm)
|VERRUCA Contact Time|
|For verrucas on the toes and instep, use the same contact time as shown for warts, determined according to verruca size. For verrucas on the heel and ball of foot, contact time can be increased up to a maximum of twice the corresponding time shown for warts – i.e. depending on size, up to a maximum of between 20 and 40 seconds.|

Bazuka Sub-Zero should not be used more than 3 times on individual warts or verrucas, and each freezing application should be at least two weeks apart.
If there are multiple warts that are close together, we recommend that each one is treated separately (to avoid multiple lesions) on a different occasion, in which case it may take a long time to treat all the warts.
Bazuka Sub-Zero can be used whenever the removal of a wart or verruca is required, excluding warts near the face, armpits, breasts, bottom or genital (sex) area. Bazuka Sub-Zero also shouldn’t be used on sensitive, damaged, cut, grazed, diseased or itchy areas of skin.
No more than 3 freezing applications of Bazuka Sub-Zero should be used for any one treatment episode for a single wart or verruca, and each freezing application should be at least two weeks apart.
If any freezing agent leaks/escapes from the bottom of the cap when 'charging', then it’s likely that the cap is being depressed for too long.
Any such escape of the freezing agent will very quickly vaporise (possibly appearing as a mist).
Take care to avoid contact with skin, clothing, fabrics, jewellery and metal or polished surfaces as it may cause permanent damage.
When 'charging' the foam applicator it is important to stand the can on a suitable surface, so that the hands only come into contact with the dome-shaped safety cap as it is depressed.
