For practical and relatively painless wart, skin tag removal or treatment for a variety of other skin concerns. 

Cryotherapy is the practice of applying extreme cold to the skin for surgical or medicinal purposes. Also known as cryosurgery, it typically uses nitrous oxide gas to destroy dead or diseased skin tissue. Nitrous oxide is applied to the skin using the Dermapen™ Cryotherapy device. 

How does Dermapen™ cryotherapy work?
Dermapen™ cryotherapy delivers a fine, targeted, ultra-cold mist (temperature -89 degrees Celsius) of nitrous oxide gas at a high pressure to effortlessly and painlessly treat a variety of unwanted skin lesions. The pinpoint accuracy of a cryo pen provides greater precision and comfort (compared with liquid nitrogen therapy), to create greater treatment versatility and results. Treatments are a fast, comfortable and effective for imperfections found on facial and body skin.

The longer the mist is sprayed onto a lesion with the cryo pen, the deeper the absorption and active penetration. Multi-treatment tips enable versatile precision to treat a variety of lesion sizes and depths. Unlike traditional cryotherapy, the tip does not directly touch the lesion. This enables far greater comfort, accelerated healing and a more precise delivery system. The nitrous oxide treats damaged tissue by freezing intercellular fluid enabling rapid removal.

Aftercare Instructions

The site will initially form a small blister which will then be replaced with a scab.

The healing process can take between 1 to 3 weeks.

The treated area is likely to blister within a few hours. Sometimes the blister is clear and sometimes it is red or purple because of bleeding (this is harmless). Treatment near the eye may result in a puffy eyelid, especially the following morning, but the swelling settles within a few days. Within a few days, a scab forms and the blister gradually dries up.

Usually, no special attention is needed during the healing phase. The treated area may be gently washed once or twice daily and should be kept clean. A dressing is optional but is advisable if the affected area is subject to trauma or clothes rub on it.

When the blister dries to a scab, you may wish to apply Bepanthen, Paw Paw cream or moisturiser, and avoid picking at it. The scab peels off after 5-10 days on the face and three weeks on the hand. A sore or scab may persist as long as three months on the lower leg because healing in this site is often slow.

Secondary infection is uncommon. When it occurs, it may cause increased pain, swelling, thick yellow blister fluid, purulent discharge and redness around the treated area. Contact the clinic if you are concerned: topical antiseptics and oral antibiotics may be necessary.

Sun protection of the treatment area is essential to reduce the potential for Hypo/Hyperpigmentation (lighter or darker pigmented areas on the skin). Ensure you cover the area and apply sunscreen on a daily basis.


A wart is primarily an infection in the top layer of your skin. This infection is typically the result of a virus in the human papillomavirus (better known as HPV) family. The virus penetrates the top layer of skin through a cut or a scratch. This triggers a fast growth of cells on the skin’s outer layer, thus forming the wart. Cryotherapy not only kills the wart off at the base but also nullifies the virus, preventing the growth of warts (at least from that virus strain) in the future. It’s a straightforward, simple wart removal solution that works.

Skin Tags
While they can be unsightly, depending on where they form, there is no real cause for health concerns from skin tags. They’re quite common and can develop anywhere on the skin, but are most commonly found on the eyelids, neck, inner thighs and armpits. Cryotherapy is a relatively pain-free skin tag removal solution in which the base is frozen with nitrous oxide. This causes the tag to blister and drops off after a few days.

Benign Moles
Though it’s essential to have any unusual lesions checked out by a medical professional and ensure they don’t change form over time, benign moles are unlikely to pose a health risk. Moles are typically round or oval and are often symmetrical. They tend to be just one shade, usually brown or skin coloured, and unlike more bad spots on the body, will have clearly defined borders. People have benign moles removed with cryotherapy for cosmetic purposes only as they typically require no treatment for health reasons.

Seborrhoeic Keratoses

Otherwise known as a ‘seborrhoeic verruca’ or a ‘senile wart’, seborrhoeic keratoses are non-cancerous, benign skin growths that appear – much like age spots – to be more prominent among older people. They can appear in a range of colours (from light tan to black) and sizes, though they will usually be round or oval. There is no known cause for seborrhoeic keratoses, though it is possibly UV related due to their prevalence on areas of the body that receive a lot of sun exposure. Cryotherapy is highly useful in the removal or reduction of seborrhoeic keratoses spots.

Cherry Angiomas

Named for their bright red colour and round shape, cherry angiomas are fairly common skin growths that are typically found on men or women over the age of 30. Their red appearance is caused by broken blood vessels located inside the growth. Also known as ‘senile angiomas’ or ‘Campbell de Morgan spots’, they are not regarded as a health risk but should nevertheless be monitored to ensure they don’t change colour or shape over time. Cryotherapy is an effective means of cherry angioma removal.

Does it hurt?

A mildly cold sensation is experienced with cryo pen treatment of larger lesions. Smaller lesions may be treated in as little as 3 seconds for fast, comfortable and pain-free results. The treated area will feel itchy and appear red immediately after application. A mild blister, then scab formation may present for up to 2 weeks post-procedure as part of the removal and healing process.

Are there any side effects?

The fine mist of nitrous oxide is precisely delivered with our cryo pen to the unwanted lesion. The surrounding healthy tissue remains unaffected. This means treatment may even be performed near the eyes and on sensitive areas. The fast penetration rate provides a reliable and exact application. Some minor scabbing, blistering or darkening of the lesion may appear immediately after treatment. This will clear in one to two weeks. Suspicious moles or sunspots will require a doctor’s approval before treatment to ensure patient safety.

How many treatments do I need & when will I see improvement?

To remove the risk of over-treatment, some lesions may require a second mist, 2-3 weeks after the initial session. Most lesions however only need one course to deliver long-lasting treatment and removal. Results may be seen one to two weeks after treatment.

How much does it cost?

The cost of cryotherapy treatment can range between $65 – $100 depending on the size and quantity of skin lesions needing treatment.
