The Histofreezer® is a form of Cryotherapy (treatment of conditions using various forms of liquid nitrogen). It is an FDA-approved treatment for wart removal.
Liquid nitrogen, housed in a pressurised canister, is sprayed onto the affected area in a controlled manner. This area of the skin reaches a temperature of -55ºC.
The uppermost layer of the skin, together with the lesion, eventually drops off. A new, healthier layer of skin replaces it. This can take any time between 10 to 14 days depending on individual recovery.
Apart from its indicated use of wart removal, the Histofreezer can also help eliminate other benign skin growths found on the body:
The Histofreezer® allows targeted wart removal and treatment of benign lesions at temperatures warmer than -60ºC, reducing the chances of scarring. Histofreeze is safe for adults, and children 4 and over.

Histofreeze is a form of Cryotherapy that eliminates common skin growths such as warts, seborrhoeic keratosis and actinic keratosis. This is done via the Histofreezer® canister.
Depending on the size of the lesion and patient recovery, most lesions resolve after 3 treatments, once every two weeks.
After assessing your needs, the doctor can get the Histofreeze done in a matter of minutes.
Upon completion of the recommended course, results can be permanent. Results vary by the individual and lifestyle choices. Repeated treatments may be required for some skin disorders.
There may be slight blistering. Minor discomfort is common and can last for up to 2 days. This can be relieved with paracetamol.
The wound healing time can vary between a few days to a couple of weeks for larger areas. Patients with smaller, less prominent lesions usually return to daily activities after treatment.
Sometimes the area may swell up, blister and can fill with blood. This is quite normal following Histofreeze. Blisters can be pricked with a sterile needle and an antiseptic cream can be applied morning and evening until the healing process is complete.
If you feel the pain is not reducing after four or five days of the treatment, and the area looks red and angry, please inform our clinic.
In addition, temporary, visible changes in the intensity of pigmentation may occur following treatment such as hypopigmentation (turning white) or hyperpigmentation (turning dark).
Histofreeze is safe for most healthy adults, and children over the age of 4. As with all medical procedures, you should be sure to disclose all of your medical history and current habits such as smoking and use of blood-thinners, medications, birth control pills, or supplements.
Histofreeze is unsuitable in the following circumstances:
Pre-care: Please shave any hair around the lesions the night before treatment. Longer, thicker hair can be in the way of treatment.
Post-care: Wash the treated area on a daily basis to keep the area clean and to gently remove any loose scabs. Avoid prolonged exposure of the treatment area to sunlight.
