Cryotherapy with liquid nitrogen is a common and widely used method for treatment of various skin conditions in dermatology.


The method is based on the local application of liquid nitrogen, which is extremely cold due to its low boiling point of -196 °C.


The extremely low (cold) temperature of liquid nitrogen freezes and destroys the targeted tissue, resulting in subsequent removal and reverse healing.


Liquid nitrogen cryotherapy is commonly used to treat the following dermatological conditions:

  • Warts - freezing and removal of common warts, plantar warts (warts on the feet) and genital warts;
  • Actinic keratoses - represent pre-cancers on the skin, caused by its damage from the effects of the ultraviolet rays of the sun. Cryotherapy with liquid nitrogen allows the effective removal of these growths and prevents their development into malignant formations;
  • Seborrheic keratoses are benign growths that appear as dark, raised patches on the skin. In such cases, cryotherapy is used to remove them for cosmetic or symptomatic reasons;
  • Molluscum Contagiosum - a viral infection that manifests itself in the appearance of small, pearl-like formations on the skin of the body. Cryotherapy can effectively remove the skin lesions associated with this condition.

Cryotherapy is performed by an experienced dermatologist using a special device or applicator with a cotton tip, through which liquid nitrogen is applied directly to the affected area.


The method is generally considered effective and relatively safe. There are some potential risks and side effects, including pain, redness, swelling, blisters, scarring, and changes in pigmentation. It is crucial that the procedure is performed by a trained and experienced dermatologist to ensure proper application technique to minimize the risks of complications.
