Hello :)
If you get a wart on your finger even once,
you start looking for ways to deal with it,
and you also learn about cryotherapy.
For those who are hearing about cryotherapy for the first time
and are wondering what it is and how it is done,
I’ll explain the things you should know before treatment,
including not only the advantages but also the disadvantages and side effects.
At the end, there’s also a realistic review from someone undergoing treatment
through an actual treatment process, so if you’re curious about the details,
please read to the end!
- What Is Wart Cryotherapy?

Cryotherapy cryo device
Cryotherapy is a method that removes wart tissue
by rapidly freezing the affected area with liquid nitrogen.
Warts that appear in thin, frequently moving areas like the fingers
can also cause inconvenience in daily life,
and once you notice them, they tend to keep drawing your attention.
Also, when a wart appears on a finger, there is a fairly high chance
that it can spread to other fingers or to family members.
So, beyond relieving cosmetic concerns,
timely treatment without delay is necessary to prevent further spread.
- Advantages and Disadvantages

Advantage of cryotherapy: short procedure time
The advantage is that it takes a short time to perform
and the recovery period is relatively short.
In fact, cryotherapy itself usually takes
less than 30 seconds,
and the supplies needed are simple.
Thanks to these advantages, it can be done right away
in an examination room or treatment room rather than an operating room.

Important nozzle size in cryotherapy
One disadvantage is that the guidelines for using the device
are not clearly standardized.
Depending on the area and size, the spray time
and nozzle selection must be chosen carefully.
If it is done for too long, the tissue freezes too deeply
and necrosis can occur,
and if it is too short, it may not freeze properly
and the wart may remain as it is.
Important note: these detailed considerations have no fixed manual
and are based entirely on the practitioner’s judgment.
You should definitely know this.
- Side Effects

Blister, a side effect of wart cryotherapy
There are three main side effects that can appear after cryotherapy.
- Necrosis
If the spray time is too long, the tissue can freeze too deeply
and necrosis may occur.
Areas with sensitive peripheral circulation, such as fingers and nails,
require extra caution.
- Blister formation
If a blister bursts, there is a risk of secondary infection
through the opened area.
At this time, applying the antibiotic ointment Eroban
can help prevent infection, and the blister will disappear within a few days.
- Pigmentation and scarring
If necrosis occurs and the skin must be surgically removed,
scarring is inevitable.
To help prevent this,
you should frequently apply sunscreen and scar ointment.
These side effects can vary greatly depending on
the spray time and nozzle size selected.
This is something the practitioner learns through experience with many cases,
and they must form their own 기준, such as deciding, “This is enough,”
or “I will never go longer than this time,” and make judgment accordingly.
- Case of the Actual Treatment Process

Dr. Choi Yoo-seop of Mutoel Dermatology
I’ll explain the actual treatment process using a case of someone who came all the way from Suwon to Yongsan, Seoul.
This person had received wart treatment before,
but did not feel any clear improvement.

Dr. Choi Yoo-seop checking the wart size, location, and condition
First, before cryotherapy,
it is necessary to check whether treatment is currently possible.
At Mutoel Dermatology, through a consultation,
the following items are carefully checked:
| Wart location, size, and current conditionDiabetes statusWhether cryotherapy, laser, or medication treatment was done elsewhere and howAllergy historyBlood clotting disordersImmune deficiency disorders |
In fact, today’s patient
had skin that had become hard when they first visited,
so immediate cryotherapy was not possible,
and after applying ointment to soften the skin for a period of time,
cryotherapy was performed.

Skin disinfection process
When doing cryotherapy on the same day,
the process, side effects, and precautions are explained thoroughly
to the patient, and then the skin is disinfected.

After that, to prevent damage to the surrounding area,
a proper size is prepared.

At this point, you may be wondering
whether cryotherapy is very painful and how intense the pain is.
Unfortunately, the degree of pain varies from person to person,
so it cannot be stated definitively.
However, in the actual treatment process video from this day,
you can check this person’s real reaction,
so if you’re curious, please take a look!
Does it all disappear after just one session?
How many sessions are needed?
You may also be curious about how long it takes
for a wart to disappear after cryotherapy.
For some, it disappears after one treatment; for others, it may take months...
It may sound vague, but this also can only be explained as
“It varies from person to person.”

Finger wart
We received the photo of the wart on the fourth finger
when it was severe directly from the patient.

Condition after finger cryotherapy
This is how it looked after the first visit to Mutoel in July,
after softening the hard skin
and then undergoing cryotherapy twice.

Progress photos of the finger wart
Fresh photo from yesterday!
This is a progress photo after the third cryotherapy session.
Although there was no immediate change after just one session,
there has been a meaningful improvement compared to before,
and the condition is being monitored continuously.
This is a video of the consent for using photos on the blog.
- Closing

Today, including an actual case,
I explained cryotherapy for finger warts.
Cryotherapy is simple, but it is a treatment that must be performed carefully
after understanding the possible side effects as well.
Because the approach may differ depending on the experience and judgment
of the person performing it,
please be sure to consult a specialist before deciding on the specific method.
If you have other skin concerns besides warts
and are wondering whether treatment is possible,
please check the first comment!
Thank you :)
