Avoca Wart & Verruca Treatment contains silver nitrate, a caustic agent used to safely remove warts, verrucas, and excess skin tissue. It works by destroying the top layers of the wart or verruca, allowing healthy skin to form underneath.
Each cutaneous stick is activated with a single drop of clean water, creating a controlled solution that can be applied directly to the affected area. Avoca is suitable for targeted treatment on hands and feet, helping reduce discomfort and appearance of warts and verrucas.
This product includes a treated application stick and an emery file for preparing the skin during repeat treatments.
