Cryotherapy & Wart Removal

Wart Freezing – Verruca Removal

What is cryotherapy? 

Cryotherapy (or cryosurgery) is the treatment of skin lesions by a cold substance, mainly liquid nitrogen. It is a relatively straightforward, almost painless procedure that involves the short exposure to liquid nitrogen or other cryogens, followed by slow thawing, also known as the freeze-thaw cycle.

This causes the destruction of selective cells, leaving cartilage and collagen intact, providing a framework for new tissue to adhere to. It also stimulates the immune system to destroy any remaining cells which might have survived the freezing temperature.

What lesions can be treated with cryotherapy?

Cryotherapy is often used in the treatment of benign, pre-malignant and malignant lesions. However, it is not recommended for those skin changes of uncertain diagnosis.

Some examples of eligible conditions include:

  • Viral warts
  • Verrucae
  • Skin tags
  • Seborrhoeic keratoses
  • Sebaceous hyperplasia
  • Molluscum contagiosum
  • Actinic/solar keratoses (sun damage)

Are there any side-effects of cryotherapy?

After a cryotherapy session, you may experience the following symptoms:

  • Mild pain on the treatment site
  • Swelling and redness
  • Blistering

Other less common reactions are:

  • Scarring
  • Pigmentation changes
  • Lesion recurrence
  • Delayed healing and ulceration
  • Local nerve damage (usually temporary)

Reasons why cryotherapy might not be suitable for you

The administration of cryotherapy is generally well-tolerated and constitutes a safe procedure for most individuals. That being said, there are certain conditions which may increase the possibility of developing an undesirable complication post-treatment:

  • Immunosuppression
  • Cold urticaria
  • Concurrent treatment with renal dialysis
  • Raynaud’s disease
  • Platelet deficiency disease


Your healthcare professional will explain how to look after the area in order to promote skin healing and ensure the best possible outcome. It is usually recommended to keep the area clean from any discharge or external contaminants.

The application of vaseline is also advisable to prevent scab formation. It is important not to pick the scab as this will encourage scarring. A dressing or plaster is not usually necessary but may be appropriate if the treated area is likely to be knocked or rubbed by clothing.


Please note cryotherapy is only available at our Oxford Street clinic.
