Frequently asked questions

About the Wartner corn pen

What is a corn or persistent calluses?

A callus (or callosity) is an especially toughened area of the skin which has become relatively thick and hard in response to repeated friction, pressure, or other irritation.

Differences with the Wartner Wart pen?
  • Lower concentration of TCA gel: The Corn Pen contains TCA gel which is less concentrated compared to the Wart Pen. The TCA gel induces a peeling of the skin. As this occurs, the thickened skin / corn will disappear and new healthy skin will form.
  • Bigger pen containing 4ml of gel
  • When used, apply only once a day
  • Tested in a self assessed study, 85% of people assessed of having a complete removal of their corn in just 1 week, clearly indicating that first visible results are reached within the first treatment period of 4 days. Effective from the first week.
Is a Medical Device less efficient than a Medicine?
Medical devices for prevention and treatment of diseases are typically as or more effective than traditional medicines, because they work directly on the root cause and/or location of the problem – for example medical devices are nowadays used to provide superior relief to patient suffering from chronicle pain due to cancer.
What is a Medical Device? What’s the difference vs. a medicine?
A medical device is typically a product that works on or inside the human body, either temporary or permanent, and is aiming at prevention, diagnosis, monitoring or treatment of diseases. The key difference versus traditional medicines is that a medical device primarily works mechanically as opposed to pharmacologically, i.e. it works alongside or with your body versus affecting the chemistry of the human cells. Nowadays medical devices are used for alleviating and treating many severe and chronic diseases of heart, brain, bladder, digestive tract etc. with a superior efficacy to traditional therapy with chemical molecules. This because they typically work directly where your body needs help.
