You should apply Bazuka Gel to your verruca, wart, corn or callus, once every day, usually in the evening. Repeat the following daily treatment routine until your verruca. wart, corn or callus has disappeared. Soak the affected area in warm water for 2 to 3 minutes Dry the area thoroughly with your own towel (to avoid cross-infection). Remove the protective yellow cap, leaving the white nozzle attached to the tube. Careful apply a thin coating (one or two drops) of the gel to the top of the verruca wart, corn or callus, and allow it to dry for a few minutes to form a small white patch which sticks to the skin and is water-resistant. There is no need to cover it with a sticking plaster. Take care to avoid the gel spreading onto surrounding healthy skin, as this may cause inflammation. Every evening for the next week, carefully peel or pick off the white patch of dried gel from the verruca, wart, corn or callus. Apply fresh gel. If necessary such re-application may be made on 2 or 3 successive days.
