What are warts?

Warts occur as a result of infection with human papillomavirus (HPV) on the surface of the skin. They can vary in size and shape and often appear on the hands, feet, or other parts of the body.

Warts can be both uncomfortable and contagious. Some disappear slowly on their own, while others require treatment. An early assessment by our dermatologists ensures proper treatment and reduces the risk of infection and recurring warts.

Why do people get warts?

When the HPV virus enters the skin through small cracks or damage to the surface, it can infect skin cells and cause small skin changes to grow.

The risk of developing warts increases if the skin's natural barrier is weakened or if the skin is exposed to moist environments, such as swimming pools or sweaty shoes. Warts can occur in both children and adults, and although some disappear on their own, proper treatment by a dermatologist can help remove them faster and reduce the risk of infection.

How do warts develop on the skin?

When the HPV virus enters the skin, it affects the skin cells, causing them to divide faster than normal. This increased cell production leads to the formation of a small, hard skin lesion, known as a wart.

The surface of a wart may vary in appearance depending on the type and location, but the process behind all warts is the same: the virus alters the normal cell growth of the skin and triggers a local skin change.

Infection and prevention

Warts are contagious through skin contact or sharing towels, footwear, or similar items. We provide specific advice on prevention so that you can reduce the risk of new warts and infection to others.

When should you seek treatment for warts?

Treatment of warts may be appropriate in several situations. It may be necessary if the warts are painful, as is often the case with foot warts, or if they spread to other areas of the skin.

Treatment should also be considered if the warts do not disappear after several months, are located in a cosmetically sensitive area, or if you want to reduce the risk of infecting others. An assessment by our dermatologists ensures that you receive the most effective and gentle treatment, tailored to both the type and location of the warts.

How our dermatologists can help you

Our dermatologists begin with a thorough assessment of your warts, examining their type, size, and location to ensure that we choose the most effective treatment. The treatment is tailored to you and the location of the warts and may include freezing, laser treatment, salicylic acid, or other relevant methods with the aim of quickly relieving and removing the warts.

In addition, we provide advice on skin care and small changes in your daily routine, as well as tips on how to avoid infection and reduce the risk of new warts. We follow you closely throughout the entire process, answer your questions, and tailor the treatment to suit you, both physically and via video consultation.
