How do I use Wartner Corn Pen?
When the Pen is used for the first time, it is necessary to fully turn the dial on the top of the pen clockwise to load the gel into the brush tip until the first drop is visible. Several full turns might be needed as the gel is stored at the top of the Pen (to avoid leakage prior to first treatment). STEP 1
Hold the pen vertically with the brush tip facing downwards. Slowly turn/click the dial on the top of the Pen clockwise to dispense the gel.
Allow the gel to flow into the brush tip for 3 to 5 seconds
Carefully apply the dispensed gel only on the corn or persistent calluses (not on healthy skin surrounding it)
Let the gel dry for 10-15 minutes before putting on clothes or shoes.  The Wartner Pen formula is very concentrated and only one drop is needed per application. Carefully cover the entire surface of the corn and not the healthy skin surrounding it. Once the treatment is completed, carefully clean the pen with a tissue before storage.

    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.
    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.
    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.
