Liquid Nitrogen for Warts Removal. Cryotherapy: Wart Freeze Off

After the human papillomavirus penetrates the body, any manifestations of this disease can only become known after a long period of time. Warts are neoplasms that occur on the skin and mucous membranes, precisely because of the effects of HPV on the body.

At the moment, there are a number of procedures for the rapid removal of such growths, their medical treatment, and you can also use folk remedies, which we will not discuss today, to get rid of them. One of the most popular methods of getting rid of such tumors is wart removal with liquid nitrogen and now we will understand all the intricacies of such an operation.

The essence of the method

The so-called cryo-destruction of warts is the process of destruction of growth cells, through the effect on the neoplasm of extremely low temperatures. The main element used for such operations is nitrogen. It is well known to everyone that it passes into a liquid state at a temperature of minus 196 degrees, and if it is higher, then the nitrogen becomes gaseous. When a specialist treats a wart with such a cold substance, all the water in its cells quickly freezes, expands and eventually the cell simply dies. Freezing can be painful, because anesthesia is injected into patients.

After the wart is completely frozen and removed, a scar remains on the body. The very same period of recovery of the skin is from several weeks to a month or more, it all depends on the number and size of the removed formation. Care should be taken behind the site of the operation until it is completely healed. Since burning the wart with liquid nitrogen only solves the problem of the visual manifestation of human papillomavirus, in parallel with the operation itself, doctors often prescribe medication as well.

Advantages of cryodestruction

I will introduce the fact that this is one of the most modern methods of removing warts, moreover, of different types, experts identify a considerable number of advantages that look like this:

  • The duration of the operation is only a few minutes, subject to the presence of small tumors;
  • The effectiveness of the treatment of warts in this way is about 90%;
  • No special prior patient preparation is required;
  • After surgery, the scars remain, but they are not pronounced;
  • There is no possibility of bleeding;
  • Reasonably reasonable price for the procedure.

Disadvantages of the method

All methods of wart removal have their drawbacks, and this is what distinguishes cryodestruction in this case:

  • It is not easy to control the depth of exposure to the affected area. Sometimes the roots of the wart remain intact, and in individual cases, the freezing is too deep and tissue repair is delayed for a long time;
  • Pain after surgery. This is especially the case when plantar warts are removed;
  • Careful care of the wound after the operation;
  • After removing the wart, its additional examination is impossible.

Despite these drawbacks, this method is used quite often and is considered very effective.

Removal of warts with nitrogen: how it happens

For carrying out this procedure, an elementary set of tools is used. In the course is a special stick, made of wood, wrapped on the tip of a cotton wool. Also, doctors use a cryoapplicator, although today in different clinics, one can find different devices, with the help of which the operation is performed. The process itself is as follows:

  • The patient is given an anesthetic directly at the site of the operation, after which a pause of 10 minutes is taken for the remedy to work;
  • A small wand with a cotton swab is used as the main device, but some clinics use a cryoprobe that emits nitrogen directly from the reservoir to the tumor;
  • Liquid nitrogen is stored in a special cylinder, and the necessary temperature is maintained there to maintain it in this form. A cotton swab is dipped into a liquid and dramatically applied to the growth. By the way, the used cotton swab should be slightly larger than the wart;
  • The stick with nitrogen is kept on a growth of about 30 seconds, since it evaporates quickly enough. Depending on the size of the formation, the number of times that a cotton swab is applied to it can vary greatly, and the force of pressure on the growth itself also varies;

  • Almost immediately the wart turns pale, but after a while, its color completely changes to white. When the so-called “fluff” is formed on the surface of the growth, which appears due to the effect of low temperature on the formation, the operation ends and the wart is considered removed. Further, the skin color at the site of removal will change, this zone will begin to swell and gradually recover;
  • In the presence of tumors that have penetrated deep into the skin, and plantar warts are such, several procedures can be prescribed by a doctor, which are carried out with a certain frequency. Extremely neglected cases, when a relapse of the disease occurs, can be treated for 5-6 months, but this rarely happens.


After the procedure, a blister always appears on the wart site, which may have a red color. This edema resolves itself and any effect on it is unacceptable.

Postoperative period

After the warts burn out with liquid nitrogen, the site of the operation turns red and begins to swell. In some cases, a blister appears in patients after a couple of hours, and some find it only the next day – this is the normal state of the affected area, it should swell in the lion’s share of cases. Inside it will be a liquid, it has a bloody color, and the whole thing doesn’t look very nice, however, you shouldn’t try to open it or pierce it.

The resorption of the blister will last about a week, and only after that a dry crust will appear at that place, which will peel off. It, of course, also cannot be stripped off, the period of full recovery of the skin will last for about 2 weeks and then, on the site of the operation there will still be a pink skin that needs care.

How to care for wounds

Since freezing of warts leads to the fact that the patient suffers sufficiently serious damage to the skin, care must be taken of the site of the operation. After a blister appears, it should be protected from damage, punctures and any mechanical effects in general. Even ordinary touch can adversely affect it, up to the formation of pus inside it and serious inflammatory processes.

Twice a day it is treated with a solution of potassium permanganate, although salicylic alcohol (2%) can be used, and such procedures are carried out exactly until the moment it disappears and the appearance of a crust. It is at the time of the restoration of the skin that one should be very sensitive to personal hygiene, since, in addition to infections that are easily brought to the damaged area of the skin, a relapse of the disease can be achieved. Let us highlight the main points to be followed in the postoperative period:

  • Do not use patches to protect the blister, as this can cause it to burst or be damaged;
  • As a protective coating, you can use a bandage or gauze bandage, securing it with a plaster, but do not press it down strongly;
  • The blister can be wetted, but only if it is not damaged during the shower;
  • With perceptible pains from the blister, you can take painkillers;
  • A wound formed after the operation should be treated only with the means prescribed by the doctor. Self-treatment in this case is unacceptable;
  • It is necessary to systematically lubricate the damaged area with antiseptics.

If any nonstandard changes are seen on the skin that the doctor did not speak about, then you should definitely refer to it. Patients may be referred to the medical center for re-examination and treatment. But It is worth noting that complications in patients occur in a very small percentage of cases.

Possible consequences

Cryo-freezing, as such, is a rather destructive process for the skin. That is why patients can observe the effects of nitrogen on the body. Of the main unpleasant moments encountered after operations, experts highlight:

  • If you immediately remove a large number of warts, regardless of whether the leg was, the arm, or any other part of the body, then after the blister disappears, the skin will peel off for a week, and sometimes more;
  • Often, after healing, a black scar may appear on the body, or just a dark one, which changes color only a month after the operation;
  • If the patient is not properly caring for the site of the operation, then inflammation, suppuration, swelling are possible; in the first days of its appearance, the swelling may burst, heal for a very long time and cause pain. This blood blister should be protected most carefully;
  • In some cases, with very large accumulations of warts, or the presence of one with very deep roots, the disease may relapse, but this depends on how experienced the doctor works with the patient.

Cost of operation

Of course, pricing will directly depend on the region of operation, the clinic itself and the number, as well as the size, growths themselves. If we take into account the clinic of the capital, the service of wart removal with liquid nitrogen will cost from 400 rubles and up to 1,500 rubles, sometimes more. The price is also influenced by the equipment used, the part of the body on which the neoplasm appeared and the depth of the lesion of the skin. In regions, prices may vary dramatically.

Who is contraindicated such a procedure

Despite the fact that cryo freezing at first glance may seem to be an excellent solution for absolutely all categories of patients, in fact this is not the case. There are a number of contraindications that will not allow some patients to get rid of warts. Of the main groups of patients who do not use the method of removing the growth of nitrogen, it is worth highlighting:

  • This therapy is not suitable for pregnant women, and in some cases, adolescents;
  • During such diseases as cold and flu, removal of warts by burning it out with nitrogen is also impossible;
  • People who have problems with pressure (in this case, diathermocoagulation may occur, where current is used);
  • There are patients who have a personal intolerance to nitrogen;
  • People with a variety of nervous disorders, including epilepsy;
  • In inflammatory processes in the area of wart removal.

The process of removing warts with nitrogen is quite simple, but you still need to be aware that not all organisms can easily transfer such an effect on tissue. Depending on the state of health, the stage of development of the growth, as well as a number of other factors, doctors will draw conclusions about whether this method is suitable in a particular case, or if you should pay attention to other options, such as a laser or a radio wave knife for removing tumors.

Alternative pharmacy options

Of course, it is strongly not recommended to independently engage in the treatment of such neoplasms; nevertheless, a pharmacy for some is the best, and even more affordable option. Of the alternative drugs that are similar in their action to the cryodestruction method, we can single out only Cryopharm and Wartner Cryo, since they are the most popular today. With their help, you can burn out a growth, and such a home method of wart removal is quite common, but it is better not to do this without consulting a doctor.







There are often cases when mistakes are made at home, due to which patients then have to undergo an even more complicated and expensive treatment. Despite the fact that the instructions are attached to each of the medicines, many are in a hurry to take advantage of the drug, admitting a bunch of missteps. Crying, how not cool, should be done by the hands of professionals, not amateurs.

Feedback on the cryodestruction procedure

Many patients note that this method of wart removal is effective, but still quite painful, and the recovery is long and requires much attention to itself. Cauterization of growths with nitrogen occurs in various clinics and conditions, because you can find the following reviews from those who have gone through this procedure:

Chelsea Gipson:

This worked for mine, but since this was my first wart ever, when people said “it worked!” I wanted to know what to expect, but I couldn’t find that anywhere. So, here’s what happened:

First bandaid: Everything turned white.
Second bandaid: The top layer of the wart started disappearing and I could see the blood vessels that were inside it were now clearly visible.
Third bandaid: It started burning while wearing it. One day was REALLY painful, but now I think I just put the bandaid on too tight. There was definitely burning though. Uncomfortable, not unbearable.
Fourth bandaid: The skin around the wart started to crack.
Fifth bandaid: The skin continued to crack and I could see the wart separating.
Sixth bandaid: Skin separating deeper. Wart was really soft but it wouldn’t budge.
Seventh bandaid: The wart stuck to the medicine, so when I pulled off the bandaid, the wart went with it.

I’m left with some raw skin that’s a bit sensitive but it feels fine. It looks like the entire wart came off, roots and all, but I guess we’ll find out if it starts growing back. :/

Sidenote: It smells horribly. Make sure you put the bandaid on tight enough to try and conceal the smell, but not too tight so it hurts.

Overall not a horrible process. But pretty gross for someone who had no idea what to expect! Make sure you follow the instructions and keep it on for 48 hrs at a time. Two of mine were only on for 24 hrs and I think that prolonged the process.

Hope this helps.


I’ve had a wart on my finger for probably around a year already. I’ve researched on it and decided to just wait for my immune system to get rid of it. Unfortunately, that day just never came. So I decided to get these salicylic acid bandaids, because it resembles that home remedy I read about duct tapes and garlic.

At first I thought it was going to be a quick process. Guess I didn’t do enough research on this. Anyway, I found out that it works by burning your skin so it kills the wart with it. Pretty much what other reviewers have commented here is what happened. Just don’t panic and make sure you follow the instructions to the letter.

It’s fairly water-resistant, as long as you stick it properly and fully to your skin where water can’t enter the padded area. I was able to take showers with it.

The whole treatment just lasted a week for me. It could be more for others, especially if you have a bigger wart. Upon removing my 5th bandaid, the wart got kinda loose so I tried scraping it off with my nail, and yea it just popped off leaving the dead skin it was in and a crater with healed skin underneath.


I don’t know if I’ve ever bothered to write a review before, but for this product, I will!
Let me first say that the plantar wart I had made me considering cutting my toe off!!! I have no idea how long I had it before I realized what it was or what to do about it, I’m going to guess a few years. Google did a good job of catching me up to speed on everything to do with warts, and how to remove them. I tried everything. I wore duct tape on my toe for months. Finally I came across Compound W on Amazon, and read the previous reviews, and have to give it a try. This is no over-night miracle; It took me a long time to get rid of the wart, but it worked, and that’s the important part.
Applying this product puts a white film over the wart. What I did was apply this in the morning after a shower, then put a band aid on during the day, then before bed, I soaked my foot in warm water and then applied it again, and another band aid. You have to let the gel dry first before covering it. Before applying new gel, I always made sure the surface of the wart was exposed by peeling off the old layer. Every few days the skin around/on the wart would look dead and I would remove it; this made the wart smaller over time. One day it was just gone, and I couldn’t believe it. It’s been a month and it has not come back.
It took me about 2.5-3 months of nearly daily care to make my wart go away. Some reviews suggested other people removed theirs in a week! Maybe mine was stubborn, but I don’t see how that was possible. This gel is an acid, and it did burn occasionally. Not all the time, but I think if I removed too much dead skin, it definitely burned. WORTH IT.
I hope this review convinces someone else to give it a try, it works and is so much cheaper than going to the doctor!


After the warts began to appear, you should not postpone the trip to the doctor on the back burner. The solution to the problem is quite simple, because cryotherapy is a reliable way to remove growths. After the operation, you just need to monitor the place of its holding, lubricate the wound, to prevent its damage and then there will be no trace of the wart.
