What is Cryotherapy?
Cryotherapy (‘cold surgery’) is a highly effective and safe procedure that is used to freeze and destroy benign skin lesions. Using liquified nitrous oxide we can painlessly and safely destroy unwanted, benign and superficial lesions on the surface of the skin, such as warts, skin tags, verrucae, milia, cherry angiomas, scars, and resistant hyperpigmentation.
How does it work?
Cryotherapy is a medical procedure that involves the application of nitrous oxide gas ejected under high pressure on to the skin. The gas is very cold which helps to freeze and destroy any benign lesions.
During the application, the tip of the CryoPen reaches -89°C. The reason for this is to create a thermal shock at the region where the gas is pointed by causing a rapid drop in temperature. The temperature drop has the effect of crystallising the fluid contents of the targeted cells, turning them into ice shards, resulting in the destruction of skin lesions as the membrane surrounding the treated cells is ruptured and destroyed.
The penetration of the cold is approximately 1mm per 5 seconds of treatment, so a 2mm sized lesion would take 10 seconds of nitrous oxide gas to treat.
What can I treat with the Cryo Pen?
Cryo Pen treats benign skin lesions on the surface of the skin. More complex lesions should be examined first and treated by a suitably qualified medical professional, so you may wish to speak to your GP about them first. It can treat lesions on the face, scalp and body including:
Viral verrucae (warts)
Solar lentigo (sun spots)
Popular nevi (moles, birthmarks etc)
Contagiosum (water warts)
Treatment is safe for all (including children and young adults, although you will need to have a consultation to determine the best course of action and whether it is suitable for your lesion).
Is Cryo Painful?
As with most lesion treatments, you’ll feel some slight discomfort while CryoPen is being applied though it is bearable and very quick. A mild stinging will follow the procedure but will dissipate within the following 30 mins to a few hours depending on the size of the lesion and where it is.
How long will it take to heal?
The treated lesions should completely heal within 1 to 4 weeks and scabs formed around the lesion will shed after a week to 10 days.
Who can have a Cryo Treatment?
Anyone who is otherwise healthy can comfortably undergo a CryoPen treatment.
However, there are a few special cases:
It is essential that a correct diagnosis of a lesion is carried out before treatment because some lesions can be related to cancer and it is quite easy to confuse these with ordinary, benign lesions. In this case a visit to your local doctor to confirm it is safe will be needed.
CryoPen may not be used if the lesions are too close to the eyes. The skin structure around the eyes is extremely thin, consult your therapist at the time of your consultation of your concerns in these areas.
Cryo Therapy is not advised for pregnant women or breastfeeding mothers, as the risks are unknown.
The cost of Cryotherapy can starts at $45 depending on the size and quantity of skin lesions needing treatment.
Please book a consultation therapists to assess the area and provide you with an accurate price.
