What is Avoca 95% pencil treatment?

Avoca Wart & Verruca 95% Treatment treats warts and verrucas effectively.  It works by removing the granulation tissues of the warts and verrucas until they have disappeared. Use strictly according to the instructions provided.

How to use Avoca 95% Pencil Treatment?

Swirl the tip of the caustic pencil in this drop for roughly 20 seconds. This will allow the active ingredient to dissolve in the water. Keep this water away from any absorbent materials, as it may cause damage or discolouration. Once the tip is wet, touch it very gently to your wart or verruca.


Diabetics should consult a doctor if treating a verruca or wart. Not for genital warts.  You should carefully read all product packaging and labels prior to use.
