At a glance
Cryotherapy is a dermatology treatment that destroys abnormal or unwanted skin tissue by freezing it with extreme cold, most often using liquid nitrogen.
When the freezing agent touches the skin, it drops the temperature of the target tissue within seconds. The cells in that area form ice crystals, their walls rupture, and they die. The body then clears away the dead tissue over the following days and weeks, leaving the surrounding healthy skin largely untouched.
Medical Condition
Dermatologists use cryotherapy for a wide range of skin lesions (spots or growths on the skin), particularly those that are benign (non-cancerous), pre-cancerous, or superficial (staying close to the skin surface).
- Common warts and plantar warts (hard growths on the sole of the foot)
- Seborrhoeic keratoses (rough, warty patches that appear with age)
- Actinic keratoses (rough, scaly patches caused by years of sun damage that can turn cancerous)
- Molluscum contagiosum (small, dome-shaped viral bumps)
- Skin tags (small, soft flaps of skin on the neck, armpits, or groin)
- Superficial basal cell carcinoma (a type of slow-growing skin cancer confined to the top layers)
- Bowen's disease (a very early form of skin cancer limited to the outer skin layer)
- Solar lentigines (flat dark spots from sun exposure, sometimes called age spots)
Cryotherapy is not suitable for every patient or every lesion. Your dermatologist will weigh several factors before recommending it.
- Lesions on areas with poor blood supply, such as the lower legs in patients with diabetes or vascular disease
- Patients with cold-induced conditions such as cold urticaria (hives triggered by cold) or cryoglobulinaemia (a blood protein disorder worsened by cold)
- Very dark skin tones, where freezing carries a higher risk of permanent loss of skin colour (depigmentation)
- Lesions where a tissue sample (biopsy) has not yet confirmed the diagnosis
- Patients who cannot tolerate the brief discomfort of freezing
Risks & Complications
Cryotherapy is generally well tolerated, but like any procedure it carries recognised risks, most of which are mild and temporary.
- Pain or a burning sensation during and shortly after the freeze, which usually fades within minutes
- Redness and swelling around the treated area for several days
- Blister formation over the treated spot, which is a normal part of the healing process
- Temporary darkening (hyperpigmentation) or permanent lightening (hypopigmentation) of the skin, more likely in darker skin tones
- Scarring, particularly if the area is treated repeatedly or if the freeze is prolonged
- Hair loss in or around the treated area if hair follicles are frozen
- Infection of the treated site if the blister or wound is not kept clean
- Incomplete treatment, meaning the lesion may not be fully destroyed and a repeat session is needed
- Nerve damage causing temporary or, rarely, lasting numbness, most often near bony areas such as fingers or around the eye
Preparation & Procedure
Cryotherapy is almost always an outpatient procedure, meaning you arrive, have the treatment, and go home the same day. No fasting is required, and you do not need to stop eating or drinking beforehand.
Before the appointment, your dermatologist may ask you about blood-thinning medications, as these can increase bruising or bleeding after the freeze. Do not stop or adjust any medication on your own. The doctor will give specific guidance about what to continue and what to pause.
Smoking and alcohol do not interfere with cryotherapy itself, but avoiding them in the days around treatment supports faster skin healing. If the lesion is in a sun-exposed area, protecting it from sunburn in the weeks before treatment helps the skin respond better.
A prior diagnostic step is sometimes needed. Your dermatologist may perform or review a dermoscopy (a magnified examination of the skin) or a biopsy (a small tissue sample sent to a laboratory) to confirm that cryotherapy is the right choice before proceeding.
The procedure itself usually follows these steps.
- You sit or lie on a treatment chair while the doctor examines the lesion and marks the area to be treated.
- The skin may be cleaned with an antiseptic solution.
- The dermatologist applies liquid nitrogen to the lesion, usually with a spray gun or a cotton-tipped probe, for a controlled number of seconds.
- The treated spot turns white and feels intensely cold, then numb, within seconds.
- The doctor may repeat the freeze-thaw cycle once or twice to ensure the full lesion is reached.
- The area is left uncovered or covered with a simple dressing. No stitches are needed.
- You are observed briefly, then discharged with wound-care instructions.
Aftercare
The treated area goes through a predictable healing sequence over one to six weeks, and most patients manage recovery at home without any special equipment.
- Expect redness, swelling, and sometimes a fluid-filled blister in the first few days. This is normal and not a sign of infection.
- Leave blisters intact if possible. If one breaks, keep the area clean and dry to prevent infection.
- Clean the site gently once or twice a day with mild soap and water, then cover it with a simple plaster if needed.
- Avoid picking or scratching the treated area, as this increases the risk of scarring and infection.
- The dead tissue will darken, dry out, and fall off on its own over one to four weeks, depending on how deep the lesion was.
- Keep the area out of direct sunlight during healing, and use sunscreen on it for at least a few months afterward to reduce the chance of discoloration.
- Attend the follow-up appointment your dermatologist schedules, usually two to six weeks after treatment, to check whether the lesion has cleared completely.
- If the lesion returns or is not fully gone, a second cryotherapy session or a different treatment may be offered.
- Contact the clinic promptly if you notice spreading redness, increasing pain, pus, or fever, as these can signal infection.
Cost & What Determines It
The cost of cryotherapy can vary widely even for what looks like the same condition, because several procedure-specific factors shift the price from patient to patient.
- Number and size of lesions treated in a single session, since each additional lesion usually adds to the fee
- Depth and type of lesion, as a thicker or potentially cancerous lesion requires a longer freeze and sometimes more than one session
- Hospital or clinic class, whether a private specialist clinic, a general private hospital, or a university teaching hospital
- Country and city where the procedure is performed, as facility running costs differ significantly across destinations
- Whether a prior biopsy or dermoscopy is included or billed separately
- Dermatologist's level of specialisation and experience with complex skin lesions
- Any local anaesthetic cream or injection used to numb the area before treatment
- Post-procedure dressings and the follow-up consultation fee
Many clinics bundle the dermatologist consultation, the freezing treatment itself, and a basic post-procedure check into one package price. Items such as a pre-treatment biopsy, laboratory analysis of any tissue removed, prescription creams for aftercare, and additional sessions if the lesion does not clear are commonly billed on top of the initial package.
BPJS Kesehatan and most Indonesian private health insurance policies do not reimburse medical treatment received abroad, so patients travelling overseas for cryotherapy typically pay from their own funds or through international health insurance that explicitly covers treatment outside Indonesia. Before travelling, ask the clinic for a written cost estimate that lists every item, including consultations, the procedure itself, post-treatment checks, and any potential extra sessions. A clear written estimate before you leave home is the most reliable way to avoid unexpected charges on arrival.
Frequently Asked Questions
How many sessions of cryotherapy will I need?
Most skin lesions need one to three sessions, though some stubborn warts or thicker growths may require more. Your dermatologist will assess the lesion after each treatment and decide whether a repeat session is needed. Sessions are usually spaced two to four weeks apart to let the skin heal in between.
What does cryotherapy feel like on my skin?
You will feel an intense cold sting when the liquid nitrogen touches your skin, followed by a burning or throbbing sensation that usually fades within a few minutes. A blister (a small fluid-filled bubble under the skin) may form over the next day or two, which is a normal part of the healing process. Most people find the discomfort brief and manageable without strong pain relief.
How soon will I see results after cryotherapy?
The treated area typically scabs over and falls off within one to three weeks, revealing clearer skin underneath. How quickly you see the final result depends on the size and type of lesion being treated. Your dermatologist will let you know if the area needs to be re-treated once it has fully healed.
How much does cryotherapy cost?
The cost depends on the number and size of lesions being treated, the type of facility you choose, and whether additional consultations are needed. Treating a single small lesion at a general clinic is priced differently from treating multiple or larger areas at a specialist dermatology centre. Requesting a written estimate from the hospital or clinic is the most reliable way to know what to budget for your specific case.
