Wartner® Pro for the removal of warts & verrucas

Works faster than most conventional liquids and gels
Visible effects as from the first week

Wartner_pen_intTCA Solution method

Current acid treatments require a long term treatment period and are often difficult to apply in a convenient and on-the-spot way. Wartner Pro Warts pen was developed with the ambition to offer a complete wart treatment based on the traditional acid method to effectively eliminate warts & verrucas in a short time period, whilst using an innovative and easy to use applicator. Our new and improved Wartner Pro pen was initially designed to treat the warts in a professional and safer way with fewer applications per treatment (only 1 per week). The pen’s ergonomic design with a click button next to anti-slip surface assures convenient and safe application of the acid and the solution is absorbed into a wart within seconds.

Easy to use 4 step application


  1. For first time usage: firmly rotate the cap 360° at least 3 times to activate the pen. If this instruction is not followed, the pen won’t be activated and will not be suitable for use anymore.
  2. Align the blue (on cap) and white (on pen) knobs. Then pull to remove the cap.
  3. Click the blue button until a small drop of liquid is visible on a paper or tissue.
  4. Place the tip of the device onto the surface of the wart and click the blue button again.
  5. Keep the tip in contact with the wart for approximately 10 seconds while applying a mild pressure. The wart generally gets covered by a typical, for the treatment, “white frost”.
  6. In case of larger warts ( > 6mm) an additional application may be required.
  7. After treatment, recap firmly. Rotate the cap and make sure the blue and white knobs are not aligned to activate the closing mechanism.
  8. Repeat the treatment once per week for a maximum of 6 weeks or until the wart has disappeared.
  • For better results, we recommend to soak the feet or hands in warm water for 5 minutes prior to treatment.
  • During the treatment period, the wart may become dark. This is normal and part of the healing process.
  • A slight tingling sensation might be noticeable. This is normal and transient. If the discomfort persists in the following days, discontinue the treatment and consult a doctor.
  • Treated skin should be protected from the sun until 30 days after treatment.
  • Once opened, the product must be used within 6 weeks
  • Make sure to rotate (do not pull) the blue cap before first usage in order to activate the mechanism. Read the instruction leaflet carefully.
  • Keep out of reach of children.
  • Do not shake the pen at any time.
