CryoPen™ is a state of the art treatment that uses extreme cold, or cryotherapy, to 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.
CryoPen 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:
- Skin tags
- Age/liver spots
- Cherry angioma
- Viral verrucae (warts)
- Solar lentigo (sun spots)
- Other pigmentation
- Plantar warts
- Condyloma (genital or anal warts)
- Popular nevi (moles, birthmarks etc)
- Contagiosum (water warts))
Treatment is safe for all (including children and young adults, although you will need to check if the clinic is insured to treat minors).
How does it work
CryoPen therapy 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 temperatures. 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 to expect during and after treatment
During treatment, you may see a frost or ice-field on top of the lesion. This shouldn’t cause any worry as the frost usually goes away within a few seconds. A common technique called freeze-thaw-freeze can sometimes be used to freeze, then defrost a frozen lesion, and then freeze it again. Here, the frozen lesion is allowed to rest for 30 seconds and then a second treatment applied whereby the tissue will freeze faster second time around and destruction of the lesion is more guaranteed.
After treatment, it is advisable to leave the area uncovered as this speeds up the healing process. However, your practitioner may apply a simple dressing or plaster if there is a chance that the lesion may get rubbed or aggravated in any way.
