What is Cryosurgery?

Cryosurgery is an advanced freezing innovation that is fast, effective and safe for the removal of benign skin lesions on the face and body.

CryoPen® Cryosurgery device delivers an ultra-cold jet of high-pressure nitrous oxide directly on to skin lesions. The nitrous oxide destroys the skin tissue by freezing the intercellular fluid and forming ice shards what rupture the cells membrane, destroying the cells.

 

The ultra-cold nitrous oxide cuts off the blood supply during the freezing process, ensuring eh client’s safety during the process.

How does Cryopen work?

  • Uses disposable N₂O cartridges to deliver quick, effective treatments

  • The N₂O destroys the skins tissue by freezing the intercellular fluid

  • Does not destroy healthy tissue as targets the area to be treated only

  • Penetration depth of 1mm per 5 seconds

  • No Downtime

​What can Cryopen treat?

  • Skin tags

  • Warts

  • Age Spots

  • Millia

  • Sun Spots

  • Liver Spots

  • Verrucas

  • Any benign skin lesion

Frequently asked questions

How are lesions destroyed during cryotherapy?


The applicator is held as close as possible to the skin lesion. 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 Cryopen it painful?


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 it 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. Lesions treated on the legs often take a little more time to heal. For larger and deeper lesions a second crust may form making the healing time slightly longer. Although it is best to try to leave the treated area uncovered, a plaster or simple dressing may be applied if it is in an area which may lead to rubbing and aggravation. It is important not to pick at the crust as this may lead to scarring.




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.




What areas can I treat?


Many different superficial skin lesions can be treated with cryotherapy including viral warts, seborrhoeic keratosis, actinic keratosis and other benign lesions. It is essential that a correct diagnosis is made before treatment as we do not treat any cancerous lesions as these are more appropriately managed and followed up on the NHS. If a lesion looks suspicious of skin cancer, you will be advised to seek advice from your General Practitioner.




Benifits of Cryopen


- The treatment is very quick, usually taking a few minutes - Sterile procedure – No incision, no bleeding, no risk of infectio - There is virtually no down time - The treatment is virtually painless - Cryopen uses state of the art cooling technology that doesn’t need dangerous cryogenic gases - No anaesthetic is needed




Does the result last forever?


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. In other instances a deep lesion eg a verruca or a wart may take several aggressive treatments to get final results




What does it NOT treat?


All melanomas and recurrent basal cell carcinomas. Melanoma can spread by any of several means including local, lymphatic and blood. Additionally, Melanoma will change to a much more aggressive form if part of the lesion is left behind undetected. Basil cell carcinoma is typically spread by local extension and you may need more extensive surgery if recurrence is suspected.




Am I suitable?


Yes, however, cautions about skin type and location should be considered prior to deciding on freeze times. People with high levels of cryo globulins should be treated with caution.




I have black or brown 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.




Can I do this during summer?


The treatment can be performed at any time of the year. During the Summer months, a sun protection factor 50 (SPF50) must be applied at least 30 before sun exposure and reapplied every 4 hours.




How much does the treatment cost?


The cost to remove one large lesion is £100 If you have multiple small areas we would treat up to 5 small lesions for £100




How long does the treament take?


The procedure takes around 5-25 seconds. It very quick and painless.




Do I need a consultation


Yes, all treatment is carried out by either Dr Alice Havard (BDS) or Dr Nick Webster (BSc, BDS). All consultations are free of charge and most of the time we can complete the procedure on the same day.
