How CryoPen Works
The CryoPen 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.
What Should You Expect During Treatment?
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.
Which Conditions Can Be Treated?
- Age/liver spots
- Cherry angioma (red blisters)
- Hyperpigmented lesions
- Seborrheic Keratosis
- Skin tags
- Warts – hands & feet
If a lesion looks suspicious of skin cancer, you will be advised to seek advice from your General Practitioner.
Benefits Of The CryoPen Treatment?
- No anaesthetic is needed
- The treatment is very quick, usually taking a few minutes
- Sterile procedure – No incision, no bleeding, no risk of infection
- There is virtually no downtime
- Cryopen uses state of the art cooling technology that doesn’t need dangerous cryogenic gases
How Many Treatments Are Needed?
You should hopefully find that one CryoPen treatment is enough. However, some lesions are harder to remove than others. In more delicate places such as 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 like a wart may take several aggressive treatments to get final results.
Can Anyone Have CryoPen Treatment?
Yes, however, cautions about skin type and location should be considered prior to deciding on freeze times.
People with high levels of cryoglobulins should be treated with caution. People with other conditions such as collagen and autoimmune disease and rheumatoid arthritis should be treated with caution. It is also not suitable for women during pregnancy, nor on areas that have previously been treated with dermal fillers.
Repeated short freezing cycles of 3 to 6 seconds at 2 week intervals are recommended if you have a darker skin type. For very dark skinned people, you may not want to have CryoPen treatment, as it will kill the melanocytes around the treated area, making the skin in that area lighter.
