What is EndWarts PEN?

Effective wart removal treatment1,2


EndWarts PEN provides a unique treatment which effectively dries out warts/verrucas on hands, feet, elbows and knees. The EndWarts PEN is an easy to use pen applicator for the self-removal of warts/verrucas. Treatment takes seconds and EndWarts Pen is applied only once a week.

EndWarts PEN contains formic acid and comes in a convenient applicator that makes the treatment quick and easy. The unique formula in EndWarts PEN helps the body to dry out and reject warts.

The pen contains enough formic acid for approximately 30 treatments. The solution is bactericidal and when used correctly, does not scar or cause infections. Since no viruses can survive in the solution, the same pen can be used by several family members. However, if you have two or more warts that need to be treated, there is no advantage in sharing it with others.

Over application and/or incorrect application can result in more severe side effects such as blisters, wounds, dark pigmentation of skin, chemical burns, inflammation, tissue death (necrosis) or scarring. The damaged area should be kept clean to avoid infection. Stop the treatment in such instances and in the case of serious skin damage, contact a doctor.

EndWarts PEN is suitable for small children, can also be used by diabetics, and pregnant and nursing women. EndWarts Pen is suitable for treating many warts.

Formic acid, which is the active ingredient in EndWarts PEN, has been proven to be very effective on warts in several clinical studies. In one such study3, 9 out of 10 people treated with EndWarts were wart free within 12 treatments with formic acid. On average, the warts disappeared after 4-5 treatments.

Quick and Easy – takes seconds, only once a week!2


The ergonomic EndWarts PEN was designed to make wart removal simple and precise. The applicator automatically delivers the correct dose when the tip is pressed lightly against the wart. Using EndWarts PEN takes a few seconds once a week, so the wart treatment does not cause stress or interruption to your day.

How to use EndWarts PEN:

1. To open, the cap is rotated until the orange strip on the pen is in line with the small cavity on the cap. Once in line, the cap can be safely pulled off the body of the pen.

2. Press the tip of the pen lightly against the wart/verruca for one second and repeat once. Be careful not to apply the solution to the surrounding skin

For a successful result, treat regularly once a week until the wart/verruca has completely disappeared, otherwise the process stops. 

Since EndWarts PEN is absorbed directly into the wart and the solution leaves no trace on the skin. For example, you can put on socks or take a bath immediately following application.

Always keep the applicator pen out of sight and reach of children!

Facts about formic acid

Formic acid is an antiseptic, biodegradable organic acid that is colourless but has a strong irritating smell. The acid is corrosive but is mainly used in wart treatments because it dries out the warts from the wart roots. In nature, formic acid can be found in very high concentrations in stinging nettles. Ants also emit formic acid when they feel threatened. For example, if you have a wound on your hand and move your hand around in an anthill, you will get a strong burning feeling in the wound.

Formic acid has many different uses. Among other things the substance is used by the pharmaceutical industry in the production of insulin. It is also used in different softening and anti-itching body oils, as well as in cures for rheumatism for relieving inflammation, pain and joint pain. Formic acid is also used in ensiling of silage crops for preservation during winter.
