|For verrucas, which are more persistent and more difficult to treat, 2 extra steps are needed prior to the treatment. First, soak the foot in warm water for 5 minutes and then rub the callous carefully with a file (widely available for purchase) to expose the persistent verruca. Dry it thoroughly so there is no water/moisture between the wart and the Wartner TCA gel. Do not apply the TCA gel when the skin is bleeding or broken. File not included.|
If there is no improvement after the first treatment period of 4 days, repeat the treatment after a break of 4 days, you can repeat this treatment schedule up to 4 times. If there is no improvement after the 4 treatment, please consult a doctor.
