How long do papillomas take to heal after cryo? Removal of papillomas with liquid nitrogen - reviews, consequences. How to remove papillomas with liquid nitrogen

Many people have had to deal with papillomas. These are small benign formations, the appearance of which is caused by a viral infection. On average, genital papillomas occur in six out of seven adults.

Most often, the need to get rid of them is provoked solely by aesthetic considerations. However, we should not forget that papilloma is a benign tumor, which, with pathological changes in the body, can take a malignant course. You can avoid such negative developments by ridding your body of unpleasant growths.

Operating principle of liquid nitrogen

Removing papilloma with liquid nitrogen is the most effective way to eliminate it. The effectiveness of the method is easy to explain by the unique properties of this chemical element. From a school chemistry course, everyone should know that at low boiling points, nitrogen becomes liquid, destructive to soft tissues. The natural properties of the substance form the basis of the cryodestruction technique.

In beauty salons and clinics, cauterization of papillomas with liquid nitrogen is carried out manually or using special equipment.

In the first case, a cotton swab is used, so this method is much simpler and more accessible, but it has a number of disadvantages. In particular, during the procedure, healthy areas of the skin that are not affected by the human papillomavirus are frozen, which results in the patient receiving additional damage to the epidermis.

The device acts more delicately and provides deeper freezing. In comparison with manual removal of papilloma with liquid nitrogen, in which even experienced specialists often make mistakes, the hardware method allows you to regulate the dosage of the chemical and the intensity of its effect on the skin.

Before going for a cryodestruction procedure, it is advisable to consult a dermatologist or oncologist. First of all, it is important to make sure that the formations are of good quality. In addition, only a doctor can choose a method for removing unwanted growths that is suitable in a particular case. An indisputable indication for the elimination of warty growths is:

Cryodestruction: is it painful or not?

The properties of liquid nitrogen make it possible to remove papillomas of any type almost completely. But for a successful procedure, it is important to take into account the size of the warty growths and the area they cover. Before removing papillomas, it is advisable for the patient to undergo a series of tests to determine the presence of infections in the body.

Reviews of the removal of papillomas with liquid nitrogen indicate the likelihood of painful sensations. If discomfort or severe burning occurs, specialists use Novocaine or Lidocaine. The patient should notify the doctor in advance in case of increased susceptibility to pain.

Brief description of the procedure

Thus, the cryodestruction session is conditionally divided into two stages. First, the specialist explains the procedure to the patient and administers painkillers. If you are hypersensitive to the above local analgesics, they should not be used.

• When removing papilloma with liquid nitrogen, it takes about 30 seconds to act on each growth.
• Then the specialist must take a minute break and then repeat the treatment.
• The total number of treatments for a wart depends on its size, but on average each papilloma is frozen three times.

Even with the most careful and careful use of liquid nitrogen, the patient suffers from healthy skin that surrounds papillomatous lesions. Regardless of the manual or hardware method of exposure, a specialist must carefully handle the growths.

Rehabilitation and healing period

The consequence of removing papillomas with liquid nitrogen may be the presence of wounds, which in most cases require several weeks or months to completely heal.

Damage to the epidermis during cryodestruction of warts is completely natural and cannot be completely avoided. As soon as the growth is removed, a swelling appears in its place, which after some time thickens. It is extremely important not to expose these areas to any impact! It is strictly forbidden to open, comb or rip them off. During the healing stage, the blisters become crusty.

After the procedure, the patient may need several weeks for tissue regeneration, so it is important to strictly follow the doctor’s instructions:

• During the first few days after the procedure, you should not use cosmetics. This restriction applies primarily to parts of the body that are susceptible to freezing.
• In the first three days after removal of papillomas, the treated areas should not be wetted.
• It is advisable to avoid direct sunlight on the nitrogen cauterization sites, wear closed clothing, gloves, a scarf, etc.
• Do not do the dressing yourself.

There is usually no urgent need for the use of potent drugs for wound healing during the recovery period. The only remedy that doctors recommend to accelerate tissue regeneration is “Hydrocortisone ointment.”

Features of the procedure: patient reviews

Turning to user reviews, it is easy to draw a conclusion about the real effectiveness of cryodestruction for papillomatosis. Some patients expect severe pain from the procedure, and when they leave the cosmetologist’s office, they are satisfied.

Many note that the recovery process was quick and painless. However, those who were inattentive to the doctors’ recommendations acquired scars in the places where the papillomas were previously located.

It is also worth noting that after removing warts with liquid nitrogen, growths may appear again. Most often this happens after manual treatment of papillomas.

Consequences and side effects

Before removing papillomas, doctors are interested in whether the patient has chronic skin diseases. Liquid nitrogen cannot have any side effects as such. In isolated cases, pigmentation of the affected skin occurs. Such changes can be prevented by promptly protecting them from the sun. Also, after eliminating warts on the scalp, focal hair growth disorders are possible.

Cryodestruction has no serious consequences or side effects. Complications, as already noted, have a chance of occurring if the patient refuses to comply with medical instructions in the postoperative period. For example, if the processes of natural tissue regeneration are disrupted by damaging the vesicles or removing the protective crust, an infection may occur. In this case, patients develop inflammation, which requires drug intervention and a strict therapeutic regimen.

Contraindications to the use of liquid nitrogen

It is not recommended to undergo such procedures for pregnant women and children under 12 years of age. With diabetes and endocrine system disorders, it is also impossible to predict how successfully and quickly the wounds will heal, and therefore it is advisable to abandon cryodestruction. The use of liquid nitrogen in a number of other cases is strictly prohibited. No doctor will undertake the removal of papillomas if:

• the growths have become malignant (in this case, complex treatment, including radiation, chemotherapy and surgery, is prescribed by an oncologist);
• the patient has an aggravated chronic skin disease (eczema, psoriasis, etc.);
• there are serious skin lesions (wounds, cuts, burns) in the area affected by papillomatosis;
• The patient has a history of intolerance to low temperatures.

Is it possible to remove papillomas at home?

If removing papillomas with liquid nitrogen turns out to be impossible for some reason, a specialist should find an alternative method for getting rid of warts.

If there are small growths, the doctor may allow the patient to eliminate the growths on their own. The pharmacy sells special products that contain liquid nitrogen (for example, Cryopharma or Wartner Cryo).

But we should not forget that using such drugs at home is not the safest way to remove unattractive growths. Only a specialist will not make a mistake with the dosage, taking into account the skin type and localization of lesions, which will avoid complications and side effects.

How much does a cryodestruction session cost?

There are a huge number of cosmetology centers in Moscow that provide services for removing papillomas with liquid nitrogen. When choosing an institution, it is important to take into account not only its pricing policy, but also the level of equipment, the availability of modern equipment and the responses of patients already contacting them.

In the capital, the average cost of removing papillomas with liquid nitrogen in one session (one growth) is about 700-1200 rubles. The price depends on the location of the damage, its quantity, and size. Most clinics offer favorable discounts if you complete a course of cryodestruction, which involves removing a certain number of papillomas.

The use of liquid nitrogen may not bring the expected effect if the freezing of warts is performed by a specialist with insufficient qualifications. When choosing an institution, you should pay attention to the availability of the necessary permits and licensing documents, and for medical personnel - the appropriate certificates.

A wart on the skin is a formation that causes discomfort. Firstly, it is ugly, and a person begins to feel ashamed. Secondly, warts often cause painful sensations: they are painful to touch, and unpleasant sensations may also occur inside the localization of the formation. The appearance of papilloma is a possible signal that a person’s immunity is weakened and it is worth taking measures to increase the body’s defenses. Of course, it is much easier to feel when the wart disappears after cauterization with nitrogen, because then the aesthetic appearance is much better, and it can be disguised.

If you do not take any measures to get rid of tumors, then they can subsequently spread throughout the body and even appear on the scalp, soles, armpits, buttocks, and genitals. The natural desire of every person who has them is to remove or cauterize the ugly growth as quickly as possible.

Removal of papillomas with liquid nitrogen is widely practiced in medical institutions of various types, from a beauty salon to a specialized dermatology clinic. The method is considered one of the most accessible, effective and inexpensive. What is the essence of the procedure, how it is carried out and what results to expect, you will learn from our article.

Cold is one of the proven methods of treating a wide variety of diseases and disorders in the human body. Thus, ultra-low temperatures form the basis of cryotherapy, which is widely used in medicine and cosmetology. The method is based on the ability of liquid nitrogen to instantly freeze tissue, which makes it possible to quickly and painlessly remove various skin tumors (papillomas, condylomas, warts, nevi).

First, let's try to understand what papilloma is and why it needs to be removed.

Papilloma is a benign neoplasm, the appearance of which... It is very easy to become infected with the virus through contact with a sick person or through everyday contact (using shared things). In the human population, this virus is extremely common; according to statistics, every sixth person is its carrier. But even after infection, HPV rarely manifests itself if the body’s defenses are in order. It is activated when immunity decreases due to various chronic diseases, stress factors, bad habits or promiscuous sex life.

Nodules appear on the body that look like warts. Their surface is lumpy and uneven, their color ranges from flesh-colored to dark brown. Papillomas can be located on a wide base or a thin stalk, be single or multiple and have different sizes.

They do not cause much physical discomfort, but are perceived as a cosmetic defect. But this is not the main danger of neoplasms. If papillomas are located in places where they can easily be injured (by friction with clothing, haircut or shaving), there is a risk of the growths degenerating into a malignant tumor.

Therefore, the best option is to remove the tumor in a timely manner and get rid of possible complications. To clarify the diagnosis, examination and referral for the procedure, you should contact a dermatologist.

So, in addition to the external defect, papillomas pose a serious health threat in terms of oncology. In addition, papillomas tend to grow into neighboring tissues and can interfere with the normal functioning of organs. Thus, a neoplasm localized on the mucous membrane of the larynx makes breathing difficult and prevents the correct pronunciation of sounds. And papillomas located on the cervix can cause cancer or the development of dangerous bleeding.

Experts warn that the tumor must be removed if:

• its color, size or shape changes;
• papilloma periodically becomes inflamed and bleeds;
• there is a noticeable tendency towards its growth.

Modern medicine knows many effective methods for removing papillomas. Some of them, such as electrocoagulation or excision with a scalpel, are already outdated. Other methods, such as laser and cryotherapy, as well as radiosurgery, are actively used. It is worth emphasizing that all of the above methods for removing papillomas are quick and painless. So, on average, it takes from a few seconds to 2-3 minutes to remove one tumor. It all depends on the size of the growth and its location.

Many patients try to reduce papillomas at home. Folk remedies such as cauterization with garlic, celandine or iodine are used. Meanwhile, many tumors cannot be removed in this way: at best, this can lead to a scar or scar, which even a cosmetologist will not be able to remove; at worst, it can cause serious complications.

As an alternative, you can use pharmaceuticals, in particular the drug Cryopharma, the effect of which is similar to the cryodestruction procedure. In any case, if you decide to remove papilloma yourself, you need to consult a specialist, especially if the growths are localized on the face or mucous membranes, regularly become inflamed or grow.

The essence of the method is that the neoplasm tissue is treated with liquid nitrogen and instantly frozen. In this case, the liquid inside the cells freezes, turning into microscopic pieces of ice that damage cell membranes and structures. As a result, the papilloma tissue is destroyed and it dies.

As already noted, the procedure for removing papillomas with liquid nitrogen is one of the most common. Its advantages include speed, painlessness and simplicity: the doctor simply cauterizes the wart with a special applicator soaked in liquid nitrogen, or uses a hardware method, using a cryodestructor attachment for treatment, selected according to the size of the tumor.

Under the influence of ultra-low temperatures, the growth freezes and collapses, and after a couple of days it dies. The procedure is carried out using local anesthesia, in which case the patient only feels cold and a slight tingling sensation. When removing a small papilloma, anesthesia may not be necessary, since the effect of cold is short-term and takes only a few seconds.

Contraindications

The following conditions are contraindications to the use of cryotherapy:

• Diseases of an infectious or inflammatory nature;
• Individual intolerance to cold;
• Oncological diseases.

The method is used with caution during pregnancy and lactation and when removing tumors in young children.

The procedure is carried out on an outpatient basis, in a specially equipped room. No preliminary preparation is required before cryotherapy. The patient is placed on the couch, an anesthetic (novocaine solution) is applied to the treatment area and wait 10 minutes for it to be completely absorbed and have an analgesic effect.

Then the doctor begins the procedure itself. A special nozzle or applicator soaked in liquid nitrogen is pressed against the growth and held for several seconds. In this case, the skin growth and the skin around it freezes and turns white.

Processing is carried out in several stages. After the first application, take a break of 1-2 minutes. During this time, the skin thaws and the doctor can determine the depth of the drug’s effect and the need for its further use. Usually, 2-3 treatments for 10-30 seconds with breaks between them are enough for complete freezing.

After the procedure is completed, the skin around the papilloma turns red and there is slight swelling. The next day, a blister filled with clear or bloody liquid appears at the site of the tumor. This is a normal skin reaction, indicating that the freezing procedure was successful.

After a few days, the blister will open with the separation of the ichor and a dense crust will appear in its place. After 4-5 weeks, it will dry out and fall off, and in its place will be clean, renewed skin.

Features of care

In order for the recovery period to pass without complications, you need to follow all the doctor’s recommendations and take care of the wound left at the site of the removed papilloma.

• For three days after the procedure, it is prohibited to wet the treatment area with water.
• The fluid-filled blister that forms in the first days after a cryotherapy session should not be touched or punctured. It will open on its own, after which a dry crust will form on the wound.
• The crust (scab) serves as protection against possible infection, so it should never be torn off. If the crust is removed ahead of time, an unsightly scar may remain on the skin.
• Every day you need to treat the wound with an antiseptic solution, which will be prescribed by your doctor. Soon the crust will dry out and fall off on its own.
• During the recovery period, you will have to forget about going to the bathhouse, sauna, swimming pool or solarium.
• At this time, you should not apply cosmetics to the treatment site or try to disguise the wound with foundation or powder.

It will take several weeks for the skin to completely heal, but even after the scab falls off, you need to avoid prolonged exposure to the sun and, to avoid hyperpigmentation, protect the skin with creams with a UV filter.

Home procedure

You can remove papilloma yourself, at home, using the special drug Cryopharm. This option is acceptable after preliminary consultation with a doctor and if the papilloma is small, not inflamed or injured.

Cryopharma is a medicine based on a mixture of propane and dimethyl ether. Its effect is similar to the procedure of freezing with liquid nitrogen. The drug should be applied to the papilloma strictly according to the instructions. To eliminate small papillomas, just one application of a medicinal solution is enough.

The drug is produced in the form of a spray, which greatly facilitates its use. After removing the papilloma, there are no scars left on the skin. Limitations in the use of the product are individual intolerance to its components, pregnancy and lactation, and diabetes mellitus (read more about the new effective drug for diabetes Diabenot -.

What is the price?

The price for removing papillomas with liquid nitrogen ranges from 300 rubles per unit. If the papilloma is large or there are many tumors, treatment will be more expensive. The final cost of the procedure is influenced by the level of the clinic, the qualifications of the staff and the amount of work (the number and size of papillomas).

Content

The traditional method of treating papillomas is to cauterize them with liquid nitrogen. In medical terminology, the process is called cryodestruction. During it, liquid nitrogen is used, the temperature of which is minus 196 degrees Celsius. The procedure is simple, helps to quickly and effectively remove formations that cause discomfort.

Removal of papillomas with liquid nitrogen

In modern medicine, cryodestruction of papillomas is considered the most effective method of removing warts, which is painless. The active ingredient is nitrogen in liquid form, which is supplied to the formation with a special cryoapplicator. Through it, ultra-low temperature is applied precisely to the wart. All this is accompanied by a subtle tingling and burning sensation, and a feeling of coldness is felt.

After several days, the area affected by cryodestruction rejects the pathological tissue, after which it quickly regenerates and recovers. Even after removing the papilloma, liquid nitrogen affects the skin - it improves peripheral blood circulation in the affected area, stimulates tissue restoration and skin nutrition.

How to remove papillomas with nitrogen

Cryodestruction of papillomas takes no more than 2 minutes. After the exposure to liquid nitrogen is completed, the tissues around the papilloma will acquire zonality - a cryonecrosis zone, a transition zone, a border of irreversible damage and a hypothermia zone are distinguished. To effectively rid a patient of papilloma, the doctor must correctly predict the border of necrosis. There is a dependence on the external size of the papilloma, but still cryodestruction occurs deeper and wider than the superficial lesion.

The cryodestruction procedure proceeds step by step as follows:

1. The doctor makes sure that the neoplasm is benign. Anesthesia with Novocaine with a low sensitivity threshold of the patient.
2. Selecting a tip based on the area of ​​the build-up. Preliminary application so that the place of contact between the instrument and the skin is parallel to each other.
3. Gradual cooling of the tissues; at a temperature of minus 80 degrees, an adhesive effect will be visible - the tip will stick slightly to the fabric. Treatment with a disinfectant.
4. The papilloma becomes white, has a dense consistency, and becomes cold. In this case, the patient alternately feels a burning sensation and tingling, then feels nothing.
5. After 3 hours, hyperemia and swelling appear around the papilloma.
6. After a day, epidermal blisters filled with liquid will appear.

Cryotherapy at home

You can remove tumors at home if they are not pointed, are not located on the face and do not show signs of inflammation with bleeding. In all other cases, cryotherapy with Cryopharm or Wartner Cryo is used. They can be bought in an online store or ordered from a pharmacy catalog. The package includes an aerosol, a holder and applicators. Due to targeted action and a temperature of -60 °C, only damaged skin is frozen and healthy areas are not affected. The wart can be easily removed within 10 days; if the result is negative, the process is repeated.

Recovery period after cryodestruction

After cryodestruction of the formations, the necrotic process begins - the tissues die within 3 weeks, but remain covered with a scab. It acts as a hygienic bandage, preventing the entry of contaminants. You cannot tear off the scab until it falls off on its own. Also, do not pierce the blisters that form after the wart dies. They tear on their own within a week, after which they should be treated with a disinfectant prescribed by the doctor and bandaged.

The rehabilitation period lasts a week; during this time, the treatment area should not be exposed to water or cosmetics. After 1.5 months, the necrotic tissue is completely rejected by the body. At the site of the papilloma, a pink spot of healthy skin is visible - the tissue is being restored and covered with epithelium. After epithelization, the new skin is protected from ultraviolet rays and scratching. Complete restoration of the dermis takes up to six months.

Is cryodestruction with liquid nitrogen safe?

The advantages of cryotherapy for papillomas are:

• no bleeding;
• low percentage of scar formation;
• ease of implementation of the method;
• no stitches, no pain;
• fast healing;
• low traumatic method;
• efficiency of treatment;
• no intoxication;
• destruction of the virus;
• low price.

Disadvantages of cryodestruction:

• 1 treatment procedure is not always enough;
• The method cannot be used for a large area of ​​damage.

Contraindications are:

• acute infectious diseases, inflammation;
• cold intolerance by a person;
• pregnancy;
• malignant formations.

Price

Depending on the level of the clinic and the size of the papilloma, removing a wart can cost from 100 to 1000 rubles apiece. In Moscow the cost is higher than in the regions. If the papilloma is located on the face, the average price for its removal will be 300 rubles, on the sole - 500 rubles. Getting rid of keratoma (dark colored papillomas) will cost 500-1000 rubles.

Removing papillomas with liquid nitrogen is a safe and effective way to cleanse the skin of benign skin elements. This method involves short-term exposure of the tumor to extremely low temperatures, as a result of which it is subjected to deep freezing with subsequent rejection of dead tissue. Adults and children can remove papillomas using liquid nitrogen. The procedure has a limited list of contraindications and, if performed correctly, does not entail undesirable consequences.

Features of the procedure, methods of its implementation

The process of eliminating papillomas with liquid nitrogen is called cryodestruction (derived from the words “cryo” - freezing and “destruction” - destruction). Some experts also call this procedure cryotherapy. What is its essence? Cryodestruction is based on freezing an unwanted neoplasm on the skin with liquid nitrogen, the temperature of which is -196 °C.

Under the influence of low temperature, the papilloma freezes, loses sensitivity and is no longer supplied with oxygen.

This process leads to irreversible destruction and tissue death of the unwanted growth. Not only papillomas are treated with liquid nitrogen. Cryotherapy is used to eliminate:

Cryodestruction of papillomas is carried out today using hardware and manual methods:

1. In the first case, the procedure is performed with a cryodevice - equipment that allows liquid nitrogen to be applied to the problem area of ​​the skin using a special nozzle, the diameter of which can be changed depending on the size of the tumor. Hardware cryodestruction is an expensive procedure, and not every clinic can offer it to its patients.
2. For this reason, most people prefer to remove papillomas manually. This option involves applying nitrogen to unwanted skin elements using a cotton swab. The manual method of removing tumors is inferior to the hardware method in efficiency and accuracy, but is cheaper. You can get rid of papillomas with its help in many clinics, beauty salons and beauty parlors.

Removing skin growths with liquid nitrogen is a bloodless procedure. When it is carried out, tissue is frozen without involving large blood vessels in the process, so the risk of bleeding in patients is minimal.

Indications and contraindications for the use of liquid nitrogen

Before starting to destroy tumors on the skin with liquid nitrogen, the patient should consult a doctor (dermatologist, surgeon or oncologist) and make sure that the unwanted growths that he wants to get rid of are not of malignant origin. Since papillomas are a consequence of activation of HPV in the body, experts often recommend that patients undergo a course of treatment with antiviral drugs (Panavir, Isoprinosine, etc.) while undergoing cryotherapy.

Papilloma is removed by freezing with liquid nitrogen if it:

Cryodestruction is considered a low-traumatic medical procedure, but it should be abandoned if:

• acute phase of a disease of infectious origin;
• inflammatory process in the body;
• allergies to cold;
• suspicion of malignant degeneration of papilloma;
• pregnancy.

Anesthesia and procedure sequence

The cryodestruction method will help remove benign tumors from any part of the body. It can be used to remove papillomas:

• in intimate places;
• in the décolleté area;
• on the face, neck, armpits, etc.

The procedure must be carried out by a specialist in a medical facility. Cauterization of papillomas with liquid nitrogen is unpleasant and sometimes even painful, so in some cases it is carried out using local anesthesia (lidocaine or novocaine). Anesthesia during cryodestruction is recommended for:

• the need to get rid of multiple papillomas or large tumors;
• removal of papillomas in intimate places and other areas of the body with increased sensitivity;
• increased pain threshold in the patient;
• carrying out the procedure on a small child.

Small warts can usually be removed without the use of local anesthetics.

In the case of anesthesia, cryodestruction should begin no earlier than 10 minutes after the administration of novocaine or lidocaine. If this requirement is violated, the medicine will not have time to be completely absorbed into the epidermal tissue and will be frozen along with the papilloma, which will increase the area of ​​the frostbitten area.

The process of removing papillomas with nitrogen consists of several successive steps:

Is it possible to remove papillomas on the eyelid using liquid nitrogen? Doctors answer this question in the affirmative. But in order not to cause frostbite on the delicate skin around the eyes, the procedure is performed not with a cotton swab, but with the jaws of medical tweezers. This method allows you to apply liquid nitrogen precisely to the papillomas and avoid damage to surrounding areas of healthy skin.

Condition of the skin after nitrogen treatment

In the first hours after the procedure, the wart subjected to freezing acquires a pinkish-white tint, which indicates the beginning of necrotic changes. The next day, a water-filled blister should form at the site of the removed papilloma. If during the freezing process the specialist managed to cauterize only the upper layers of the skin, the liquid in the bubble will be transparent and colorless.

If during the procedure the subcutaneous fatty tissue penetrated by blood vessels was affected, the contents of the blister will acquire a reddish tint. Of the 2 options, the first is preferable, since deep freezing of skin tissue can subsequently lead to the formation of scars.

The bubble formed after freezing the papilloma with liquid nitrogen cannot be punctured. It must be allowed to open on its own (usually this takes from 5 to 7 days). Afterwards, the problem area should be blotted with sterile gauze and sealed with a bactericidal adhesive plaster or covered with an aseptic bandage. Gradually, a crust forms at the site of the blister. You need to wait until it falls off on its own, then there will be no scar left on the frozen area.

If the papilloma is small, and the time of its contact with liquid nitrogen did not exceed 5 seconds, then a bubble may not form after cryodestruction. In this case, the necrotic process is indicated by slight swelling, soreness and darkening of the skin element. If a few days after the procedure the tumor falls off on its own and a scab forms in its place, the patient should not have any concerns about the absence of a blister.

After the crust falls off, in its place you can see young, healthy epithelium, which will gradually acquire the same shade as the rest of the skin.

Large papillomas cannot always be destroyed on the first try. In this case, the person should re-freeze the skin element 3 weeks after cryodestruction. After the second procedure, most patients manage to be completely cured of the tumors that trouble them.

Skin care after freezing, adverse reactions

People who have undergone cryodestruction of papillomas should avoid contact of the treated surface with cosmetics for 10–14 days after the procedure. Areas of skin that have been frozen can be washed with warm water and soap, but avoid using washcloths or other objects that can damage the blister or scab that forms in its place. To protect the affected area from sunlight during the warm season, it is recommended to use creams with a UV filter.

It should be borne in mind that after removal of papillomaviruses by cryodestruction, a person may experience side effects in the form of:

• increased skin pigmentation at the site of exposure to cold;
• scars.

Skin pigmentation is most often observed in dark-skinned people or in patients with intense tanning. To minimize the likelihood of its occurrence, the patient, after removal of papillomas, should avoid prolonged exposure to direct sunlight for 3-4 weeks. Increased pigmentation of the skin is not an irreversible side effect. A few months after cryodestruction it disappears without a trace.

Scars after removal of papillomas occur when the procedure is carried out carelessly, resulting in deep damage to the skin tissue by liquid nitrogen. To avoid their occurrence, cryodestruction should be carried out in a clinic or beauty salon with a good reputation.
