All about warts

Most warts look like skin-coloured, callused bumps that are somewhat harder and rougher than normal skin. In some cases warts are dark in colour and sometimes have a black tip. This black dot is usually a blocked blood vessel. Warts are between 1 and 10 mm in diameter. Read more about warts here.


Warts are caused by an infection of the skin with the human papilloma virus. Warts are very contagious and can easily be transmitted. Once the skin is damaged, the virus can enter the skin.

The virus can hide on surfaces that have been infected by a wart. By direct skin contact with such surfaces (or with a wart itself), the virus may spread. On rough surfaces and items such as gloves, shoes, socks and towels the virus can easily spread. Be aware that the virus can also be transmitted to other places on your own body.

Swimming pools and sports facilities

In rooms where many people gather, the risk of getting warts may be higher. In swimming pools and sports facilities there may be more contact with rough surfaces and skin contact may occur through the feet. It is advisable to wear flip-flops and wash your feet thoroughly with soap afterwards, and then dry them completely.

Moist environment

Warts are more easily formed in a moist, humid environment. Swimming pools, saunas and shower cubicles are all places where the virus spreads easily. Poorly ventilated shoes (in which sweaty feet develop) can also contribute to the development of warts. It will therefore help if you wear well-ventilated shoes and cotton socks to prevent sweaty feet.

Yes, there are different types of wart. Here we describe seven important types which have different external characteristics and which may occur on different parts of the body:

  1. Common warts
  2. Verrucas (plantar warts)
  3. Flat warts
  4. Skin tags
  5. Periungual warts
  6. Genital warts

Read the description of each kind of wart here.

Note: Forwarts is recommended for common warts on hands and feet and for verrucas (plantar warts).

All about Forwarts Wart Remover

Forwarts freezes the wart to the core with a precise jet of cooling gas. This causes the wart’s cells to break down and the immune system will then remove these dead cells. Ten to 14 days after the treatment, the wart will fall off the skin. Forwarts is a ready–to-use product.

The application of Forwarts explained in three simple steps:

STEP 1: Place the nozzle over the wart.

STEP 2: Press the button with your thumb.

STEP 3: Spray the wart for 10-15 seconds, depending upon the location of the wart.

Warts on hands

Warts on hands should be be treated for a maximum of 10 seconds per treatment.

Verrucas (plantar warts)

For verrucas on the sole of the foot a treatment of maximum 15 seconds is recommended. For warts on the top of side of the foot a treatment of maximum 10 seconds is recommended.

Note: If there is a lot of callus on the wart, we recommend that you soak the skin in lukewarm water beforehand and remove excess callus. Ten minutes’ soaking is sufficient to improve the result of the treatment. Dry the skin carefully with a towel before starting the treatment. Then wash this towel at a minimum of 60°C to prevent further spread of the virus.

Note: it is strongly recommended to use a stopwatch during the treatment. Overexposure to this gas can cause frostbite.

  1. If the wart is considerably smaller than the Forwarts nozzle, we recommend that you place a suitable safety patch around the wart. This protects the healthy skin from the cold and ensures that it is not damaged. Please note that the maximum effect is achieved when a small strip of surrounding skin (1 mm) is frozen together with the wart.
  2. When the skin surface does not properly connect to the nozzle, it is also recommended to use a safety plaster.
  • After the treatment, a blister may develop under the wart. This is normal. Do not damage this blister! This may lead to infection.
  • Keep the wart and surrounding skin clean, possibly using a sterile plaster and/or bandage, especially if the blister is damaged.
  • Avoid, as much as possible, exposure of damaged skin to direct sunlight during the first 14 days after treatment.

Forwarts uses a direct, continuous freeze spray. This has two advantages over conventional methods:

  1. With Forwarts, the cooling gas is sprayed directly on to the skin. This ensures maximum efficiency from the freezing gas. With conventional methods, the gas is often transferred via a foam applicator (or other intermediate part). A lot of cold is ‘lost’ because the intermediate part needs to be cooled down before the cold reaches the wart. Also, a lot of cooling gas is lost because it flows away or evaporates during treatment.
  2. With Forwarts, the cooling gas is sprayed continuously on to the skin. This creates a flow of air that blows away the natural body heat around the skin. The cooling gas thus retains a direct path to the wart and can therefore freeze it into its core. This is also called the ‘frostbite effect’.
  • Forwarts has a short treatment duration of only 10-15 seconds.
  • Due to the direct administration method of Forwarts, the treatment is significantly colder and therefore more effective.
  • Forwarts is ready to use and extremely user-friendly. No assembly or intermediate steps are required prior to treatment.

The cooling gas in Forwarts is dimethyl ether (DME). This is an organic compound that is often used as an environmentally friendly propellant in aerosols.

Forwarts is suitable for warts (on hands) and verrucas (warts on feet) with a diameter of 1-10 mm. Consult a doctor if you have any doubts about which type of wart you are dealing with. It is also suitable for cases of stubborn warts or warts larger than 10 mm.

Yes, Forwarts is suitable for children from 4 years of age.

Forwarts has been developed to ensure extremely accurate treatment of the wart. The patented valve system delivers a controlled jet of coolant gas to the wart so that it is frozen very precisely. The treatment is very well tolerated by children, especially when using the safety plasters supplied. A normal treatment takes 10 seconds and is done before you know it!

This varies for each wart. Most small and medium sized warts will probably fall off the skin after one treatment. Larger and more stubborn warts will need two or more treatments in some cases.

Following treatment, it usually takes 10-14 days before the wart falls off the skin. If the wart does not fall off after six treatments, we advise you to consult your GP or dermatologist.

Forwarts contains enough cooling gas for at least 10 treatments. There are also 10 protective plasters included in the packaging.

A wart does not fall off the skin immediately after applying Forwarts. Following treatment, it takes on average 10-14 days before the wart falls off the skin.

Is the wart not yet gone after six treatments? Then we advise you to consult your GP or dermatologist.
