How do I use Wartner Corn & Callus Pen?
When the Corn 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. Multiple 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.
STEP 2
Allow the gel to flow into the brush tip for 3 to 5 seconds
STEP 3
Carefully apply the dispensed gel only on the corn or callus (not on healthy skin surrounding it)
STEP 4
Let the gel dry for 10-15 minutes before putting on clothes or shoes. The Wartner Corn & Callus Pen formula is very concentrated and only one drop is needed per application. Carefully cover the entire surface of the corn or callus and not the healthy skin surrounding it. Once the treatment is completed, carefully clean the pen with a tissue before storage.

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, delivering either temporary or permanent impact, and is aimed 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 chemistry of the human cells. In general medical devices are used for alleviating and treating severe and chronic diseases of the heart, brain, bladder, digestive tract etc. with superior efficacy to traditional treatments using chemical molecules. This is because they typically work directly where your body needs help.
How is it different to the Wartner Verruca & Wart Removal Pen?

  • Bigger pen containing 4ml of gel
  • When used, apply only once a day
  • In a pilot study, 85% of people assessed had complete removal of their corn or callus in just 1 week, clearly indicating that visible results are seen within the first treatment period of 4 days.
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 used nowadays to provide relief to patients suffering from chronicle pain due to cancer.
