Histofreezer – Wart Removal System
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.
How the histofreezer works
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.
Histofreezer treats a range of common lesions
Apart from its indicated use of wart removal, the Histofreezer can also help eliminate other benign skin growths found on the body:
- Skin Tags
- Genital Lesions
- Actinic Keratosis
- Seborrheic Keratoses
- Molluscum Contagoisum and more.
Benefits of histofreezer
- As a US FDA-approved treatment system, the efficacy of Histofreeze has been proven through clinical studies and use
- Because the lesion is frozen off, any stinging or burning sensation felt during the treatment will rapidly fade away during the thawing phase
Safety of the histofreezer
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.

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.
