In 2011, Wartner launched a ground-breaking new Verruca and Wart Removal Pen containing Trichloroacetic acid, a unique active ingredient, which eliminates verrucas and warts up to three times faster than conventional liquids and gels. In addition, the new Verruca & Wart Removal Pen has a precise applicator that is much easier to use than conventional acid/liquid treatment products.
