CryoPen™ uses extreme cold, otherwise known as cryotherapy, to remove skin blemishes, allowing you to improve the appearance of your skin without resorting to a surgical procedure.
CryoPen™ involves the use of nitrous oxide which is emitted under high pressure. This freezes the inter-cellular fluid, which destroys the tissue. This method allows for millimetre accuracy, so no healthy tissue is affected.
There are many benefits to using the CryoPen™, including:
You will be a suitable candidate for CryoPen™ treatment if you have a skin lesion which you are wishing to have removed.
You will need to be at least 18 years old to undergo treatment at Centre for Surgery.
Prior to undergoing CryoPen™ treatment, you will need to ensure you have the correct diagnosis of your skin lesion. CryoPen™ can only be used to remove benign skin lesions.
If your skin lesion is too close to delicate body areas, such as your eyes, this treatment will not be suitable. Those who are pregnant or breastfeeding may not be suitable for this procedure.
Before having any treatment, you will be required to attend a consultation with one of our surgeons, who will be able to assess whether CryoPen™ is the best method for you.
The CryoPen™ treatment involves holding the applicator as close to the skin as possible. The applicator will then be quickly moved away and toward the skin. The length of time this takes will vary, depending on the size and depth of the skin imperfection. Generally, this can take anywhere from 2 – 30 seconds. Once this is complete, the area will thaw for 30 seconds, before a second round occurs.
You may feel a slight discomfort during this procedure, as temperatures from the CryoPen™ can reach -89°C. You may also experience stinging after the procedure, which may last up to one hour.
The area that is treated will turn white when it is frozen. Once the area thaws, it will turn red and a weal will appear. This may then blister or crust over, with the skin lesion generally falling off after 10 to 14 days. If the lesion is large or deep, it may take longer for it to fall off. Make sure you do not pick or scratch at the blister or scab, as this can result in scarring.
This is a non-surgical procedure, so you will be able to return home as soon as the procedure is finished.
The treatment area should completely recover within one to four weeks. You may notice the skin colour beneath the lesion is slightly different, however, this is only temporary and the skin colour will eventually change.
It is recommended you have a follow-up appointment with your surgeon so they can see your progress and remove any other lesions. If the lesion is persistent and doesn’t respond to the initial treatment, you may need another treatment session, which should take place one to four weeks later.
CryoPen™ is a new, innovative applicator which removes skin lesions through the use of cryotherapy.
CryoPen™ treatment is considered to be a minimally invasive, non-surgical treatment, which does not involve any incisions. It does not involve the use of any anaesthetic.
CryoPen™ can be used to remove:
You will have to ensure your skin blemish has been diagnosed as benign. We are unable to remove any cancerous skin blemishes or any melanomas.
Those with dark skin may require repeat sessions to remove the skin lesion.
Those with very dark skin may not be suitable to have CryoPen™ treatment, as the skin beneath and around the lesion may appear lighter.
There are many benefits to undergoing CryoPen™ therapy, including:
You will generally not require repeat sessions.
However, if you have large, deep or multiple lesions, you may require another session to remove the skin lesion. This can be done one to four weeks after the initial treatment.
You may feel some minor discomfort during the treatment as the skin lesion is being frozen. You may also experience some stinging following the procedure, which should last about one hour.
You will be able to return home immediately after the procedure.
You may notice a change in the skin colour beneath the removed lesion, however, this is temporary and will return to normal after a few weeks.
After treatment, it will take around 10 to 14 days to fall off. Prior to this, the lesion will thaw, and often blister or crust.
If the lesion does not fall off you may need to have another treatment session.
You will generally not have a scar as a result of CryoPen™ treatment, as it does not involve the use of any incisions.
You may notice either hyperpigmentation or hypopigmentation of the skin. This will resolve itself within a few months. Any changes to skin colour is more likely for those who have darker skin.
