Warts are usually neither painful nor dangerous. Appearing in a visible place, such as on the hands, face, or neck area looks unaesthetically. Growing on the feet can provide discomfort while walking. Therefore, it is very natural that we want to get rid of them as soon as possible. Surgical procedures are not necessary to do this. We can use one of the most effective methods of removing warts and other skin structures − liquid nitrogen or otherwise called "cold" therapy (cryotherapy). 

What are warts?

Warts are a viral skin disease caused by the human papillomavirus (HPV). This infection affects the growth of skin cells of various sizes and can occur anywhere in the body. 

Warts can be varied. Warts usually appear on the hands, face. These are raised skin formations with a rough surface. If the warts are not large, they do not cause any complaints or discomfort, except when they occur in the aesthetic zone. If a wart forms on the feet or is large, it can become painful and sensitive to touch.  It causes pain when walking or standing. Warts can also form on the feet, where they grow deep and are very often confused with scabs. 

Is it necessary to remove the wart?

Warts usually do not cause complications and are removed for aesthetic reasons that cause psychological discomfort. They can also disappear on their own without treatment. Because warts are caused by human papillomavirus, warts are easily contagious. Damp or soaked skin is not resistant to the virus, which is why it is most commonly caused by warts in swimming pools and saunas. Also, when immunity is weakened or with the use of immunosuppressive drugs, they can start to grow, spread throughout the body, and sometimes even become malignant. Warts that grow on the feet are constantly traumatized while walking, so it can start to hurt. 

How is liquid nitrogen treatment better than other treatments?

Warts can be removed with a variety of treatments. They can be treated at home using salicylic acid preparations or in the doctor's office by surgery, removal with a laser or electrocautery. However, these methods are more vulnerable to healthy surrounding tissues, more likely to form scars, the treatment itself may take longer, or the period after the procedure may be more painful.

Therefore, the treatment of warts with liquid nitrogen is most recommended when it is important to preserve healthy tissues, which is very important in aesthetic areas, such as the face, ear cup. In addition, treatment with liquid nitrogen is also recommended for the treatment of warts formed on the feet, as removing them by other methods is likely to cause more discomfort or even pain when walking than before. 

Why is it necessary to consult a doctor before treatment?

The treatment of warts is very individual, so a doctor's consultation is necessary before the procedure. During the consultation, the doctor will examine the wart with a special device (dermatoscope), which greatly zooms in on the surface of the skin and therefore the doctor will be able to accurately assess the condition and type of wart and decide on the number of treatments required. Warts and papillomas indicate that your body has a virus, and changing moles can signal much more serious health problems, so it is imperative that skin formations be evaluated by a specialist before the procedure. 

How does liquid nitrogen treatment work?

Under normal conditions, nitrogen is a gas, and nitrogen gas is converted to liquid at about −195.6 °C, so liquid nitrogen is the best refrigerant. Nitrogen on the wart freezes the cytoplasm of the cells and causes the wart cells to die. After only 1 minute of contact with liquid nitrogen, the skin cools to −90 °C at a depth of 2 mm, and after 2 minutes. −125 °C. Depending on the location, size, and type of wart, the doctor selects the required duration of liquid nitrogen application and determines the number of procedures. The procedure is not painful if it is a short duration of liquid nitrogen application. If longer applications are required, your doctor may use local anesthetics. 

A blistering, dark scab may form at the site of the procedure. The blisters themselves rupture immediately after the procedure, and lymph flows out of them. If the blister peels off without the skin forming, a small wound remains that needs to be protected from contamination. Detailed post-procedure care recommendations will be provided to you by your doctor. 

Is one procedure enough to remove warts?

We often want the skin derivative that has been growing for several years to be removed immediately, in one procedure. However, 3 to 6 procedures may be required depending on the size, type, and location of the wart. For example, plantar warts grow deep and are often covered with a fairly thick layer of scaly skin, so their treatment may take longer. Your doctor will tell you the exact number of procedures you need during the consultation. It should be noted that it is necessary to perform all procedures prescribed by the doctor. The intervals between procedures should not be very long, otherwise the wart will not be completely removed and may be removed again later.
