Frequently Asked Questions 

What is Cryotherapy?
Cryotherapy is the use of extreme cold produced by liquid nitrous oxide for the fast, effective and safe solution for the controlled destruction of unwanted skin imperfections.
What is the CryoPen?

The CryoPen™ is a FDA and CE registered advanced cryotherapy innovation. It is a pen-like instrument which delivers a fine pinpoint spray of liquid nitrous oxide at a constant temperature of minus-127 degrees under high pressure which allows the therapist to work with millimetre precision. This means the nitrous oxide is delivered directly to the treated area and not to the healthy surrounding tissue.

How are lesions destroyed during Cryotherapy?

The applicator is held as close as possible to the skin imperfection and moved quickly towards and away from it. This could be from 1-30 seconds, depending on the size and depth of the lesion. The CryoPen™ freezes at a rate of approximately 1mm per 5 seconds.

The nitrous oxide destroys the tissue by freezing the inter-cellular fluid in a matter of seconds, forming ice shards and crystals which rupture the membrane, thereby destroying the cell. That means there will be no collateral damage to healthy tissue. It’s so incredibly accurate and practical.

Is there pain with the procedure?

There will be a mild sensation similar to a stinging nettle on the skin when the nitrous oxide reaches the bottom of the area. There might be a little residual stinging for a few minutes after treatment and the area can be slightly itchy for about 10 minutes after the procedure. Most patients get an anaesthetic effect from the extreme freezing temperatures.

What does the area look like after treatment?

During the procedure, the area freezes and turns white. After this white area thaws, a flushing occurs and the area will turn red and a weal will form. After 2-24 hours after being frozen the weal may turn into a blister which may take several days to dissolve, however this is very rare. A crust will form over the lesion, which typically, after about 10 to 14 days, will fall off and the skin will then be healed. The skin may appear lighter in colour or pink, which then returns to its normal colour over a period of a few weeks. 

Will there be scarring?

Rarely. Both hyperpigmentation (darkening of the skin) and hypopigmentation (lightening of the skin) may occur temporarily after cryotherapy. Both generally last for a maximum of a few months. Pigment change is more common in darker skin types.

How permanent is the cure?

For most lesions, cryosurgery is a permanent removal. Some lesions are harder to remove than others. In more delicate places eg the eye area, a shorter freeze time with a repeat procedure may be required to get a final result with the least damage to the surrounding skin. 

What if I have darker skin?

Repeated short freezing cycles of 3 to 6 seconds at two week intervals are recommended if you have a darker skin type. For very dark skinned people, you may not want to have cryosurgery, as it will kill the melanocytes around the treated area, making the skin in that area lighter.

How is cryosurgery better than other methods of removing skin lesions?

Cryosurgery requires no anaesthesia and has less scarring than other techniques of skin lesion removal with minimal post-op care.


The Cryopen treatments are performed by Anastassia. We offer a free consultation to allow you the opportunity to meet with Anastassia and discuss your area of concern. You will be advised how the treatment works, the cost and what you can expect during the treatment and post treatment. Any possible risks involved will also be explained so that you can make an informed decision as to whether the treatment is right for you.

Your suitability for the treatment will also be assessed and honest advice will be offered where it is professionally believed that you may not be a candidate for that treatment or perhaps where an alternative treatment may be better suited.
