Cryotherapy also known as cryosurgery is the present day customary technique for the treatment of virulent lesions, diseased tissues, and even the cancer cells. This surgery is the second most option after the skin excision approach.

Description And Symptoms
Effects/ Causes

Cryotherapy or cryosurgery or cryoablation- different names but the same meaning and function. The technique is used by a dermatologist since centuries commonly for curing the benign lesions, warts, moles, cysts and other damaged tissues. The word cryo in cryotherapy means cold and hence for treating the pernicious tissue they are stacked in a low temperature may be Zero so as to create freezing state for them and destroy them so during cryotherapy liquid nitrogen is used as a freezing agent who is exposed to deaden tissue. Apart from this cryosurgery is also beneficial in relieving the individuals from painful irritated nerves.


  • Irritated nerves
  • Pain and inflammation
  • Lesions Moles
  • Skin tags
  • Nodules

The Cryotherapy is the well-known treatment used by physicians for skin troubles. This application involves the extremely cold temperature more than the normal so as to smash the damaged cells, Liquid nitrogen used as cryogen is applied on the skin part which needs to be treated with the help of cotton swabs. This mechanism of cold exposure works promptly as living tissues either healthy or disease cannot stand the cold temperature and hence get scattered clearing the area of skin.


The Cryotherapy is categorised into three phases:

Heat Transfer: On the outer region of skin liquid nitrogen directly transfers heat, and for inner tissues, an incision is made for the heat transfer.

Cell Injury: After the heat provided to the cells, the frozen damage can be seen as cell injury.

Inflammation: The last is the blister formation

Results: The pain moles and other skin infections get suppressed and the white blood cells wash out the dead tissues

Cryotherapy is a non-invasive treatment for all those people seeking faster recovery. Henceforth it has many proven applications in eradicating skin disparities. It has many advantages.


  • Decreases inflammation at a faster rate.
  • Faster surgical procedure
  • Much rapid recovery
  • Improvesthe skin appearance
  • Reduces pain, stress, and anxiety
  • Effective in managing chronic pain
  • Powerful n assisting chronic pain
  • Less scarring of tissues Less traumatic


This surgery is used for the causes like-damaged tissues, irritated nerves, moles and other lesions.

It consists of few risks including:

  • Freezing may affect the lungs and other normal structures.
  • Headache pain and blister formation.
  • Excessive crumbled tissue formation.

The risks are less effective than any other surgery so it should not be of prime concern as the dermatologists and surgeons do take care earlier prior to the surgery.

What is Cryotherapy?

 As a cosmetic treatment, cryotherapy uses extremely low temperatures—typically liquid nitrogen to freeze and remove unwanted skin lesions or tissues.

What is the purpose of cryotherapy?

Cryotherapy is a common treatment for lesions, which are odd-looking growths or patches on the skin. These lesions may appear as:

  • Benign (not cancerous).
  • Precancerous, like actinic keratosis, which looks like scaly patches and could turn into cancer.
  • Skin cancer that is superficial to the skin's surface.
To protect the skin around these lesions and reduce scarring as much as possible, cryotherapy is also performed.

How is cryotherapy performed?

Using extremely low temperatures, a doctor treats problematic areas with cryotherapy. The cells are unable to withstand the intense cold and die as a result of the treatment.  The doctor can use different substances like liquid nitrogen, liquid nitrous oxide, or argon gas to get the temperature as low as possible for cryotherapy.

Cryotherapy is recommended for which conditions?

Cryotherapy is a simple, less intrusive method that doctors employ to treat a variety of medical conditions.

  • This type of treatment aids in the removal of damaged or infected tissue caused by various medical conditions. 
  • In contrast to open surgery, cryotherapy doesn't require large incisions. After the treatment, the majority of patients recover quickly and don't feel much pain. 
Doctors may recommend cryotherapy for conditions such as
  • precancerous cells in the cervix, liver cancer, prostate cancer, bone cancer, and cervical cancer.
  • It's also used for skin issues like warts, skin tags, and dark spots, as well as certain childhood eye cancers like retinoblastoma.

Is Cryotherapy painful?

Many feel extremely cold, so some people may have tingling, numbness, or a pins and needles sensation; however, these symptoms usually go away after the treatment. After cryotherapy, there may be some discomfort and a burning sensation when the skin heats up, and you might also feel sore for a few days. However, the discomfort is temporary and subsides after the treatment.

What are the side effects of cryotherapy?

Redness, swelling, and blistering at the treatment location are common side effects. These are usually temporary symptoms that occur during the healing process.

How many cryotherapy sessions are generally needed?

The number of sessions depends on the conditions that need to be treated. While some lesions may respond best to several treatments, others may be successfully treated in just one session.

Is there a downtime post-treatment?

The recovery period after cryotherapy is short. After the operation, patients may normally get back to their regular activities right away, although there may be some temporary restrictions depending on the treated area.

What to avoid after cryotherapy?

After treatment, don’t use fragrant soap, lotion, or cosmetics on the treated region until it has fully healed, which is normally at least 10 days. In the treated area, you may notice some hair loss.

When is it best to not use cryotherapy?

 It is not advised to use cryotherapy for:

  • Skin issues that haven't been diagnosed
  • Pregnant women
  • Melanoma
  • People with darker skin tones
  • Lesions that require tissue analysis
  • Areas with poor blood circulation
  • Individuals who cannot tolerate, or have previously experienced, the side effects of cryotherapy
  • Young kids
  • Unconscious patients
  • Conditions worsened by exposure to cold, such as:
Raynaud's syndrome Urticaria in cold weather Cryoglobulinemia Multiple myelomas
