What is Cryopen Cryotherapy?
Cryotherapy or Cryosurgery is a quick and relatively pain free, highly effective and safe procedure that is used to destroy benign skin lesions such as:
Warts, Skin Tags, Verruca, Cherry Angioma, Milia, Age Spots
Liquefied nitrous oxide (N20) is used to destroy the tissue by freezing the cell fluid, which in turn causes it to crystallise and ultimately destroy the targeted tissue
Cryotherapy is quick allowing you to be in and out insinuates, with the treatment itself often only taking a few seconds. It requires no anesthesia and has minimal scarring. You can return to normal activities straight after treatment.
The Cryopen is a unique pen like device allowing us to deliver highly accurate and targeted treatments by emitting a fine jet of N20 under high pressure directly onto the targeted area, meaning no healthy tissue will be effected during treatments.
How does it work?
- First Freeze Cycle: The treatment is administered by the clinician by holding the applicator as close as possible to the lesion. Moving it quickly to and fro whilst applying a jet of nitrous oxide onto the lesion we cause the area to freeze. This treatment time can last from 1 to 30 seconds dependent on the size of the area being treated.
- Thaw: After the first freezing cycle the tissue will be allowed to thaw for about 30 seconds.
- Second Freeze Cycle: A repeat of the first freeze cycle except this time the tissue will freeze faster than the first time
How safe is Cryotherapy?
Cryotherapy is a relatively low risk procedure, which is targeted by the Cryopen delivering the N20 directly onto the lesion and not the healthy surrounding tissue. Cryopen is both CE and FDA approved.
How Long do Cryopen treatments take?
The penetration rate of freezing with the Cryopen is approximately 1mm per 5 seconds, with a maximum freezing depth of 3 to 6mm the duration of the treatment will depend on the surface area and the thickness of the tissue being treated. Total treatments can be over in minutes.
Is it painful?
The treatment itself is painless, however there may be some residual stinging for a few minutes after the treatment has finished. Occasionally a blister may form and persist for a few hours.
How many treatment sessions will I need?
This will depend on the surface size and depth of the lesion but many treatments will only require 1 visit, although we recommend a follow up 2 to 4 weeks after the initial treatment to check on progress.
Can you treat darker skin?
Yes, however we recommend shorter freezing cycles and more repeated treatment sessions. For example a 3 to 6 second cycle every 2 weeks.
