What is the Cryotherapy for moles, wraps & keloids?
Cryotherapy is a simple non-surgical and non-invasive procedure in which liquid nitrogen is used to freeze and destroy growths on the surface of the skin. This is an effective treatment for precancerous skin lesions (actinic keratoses), as well as other skin conditions such as warts, keloids , skin tags and moles.
How does Cryotherapy work?
Cryotherapy is very quick and straightforward procedure performed as an outpatient treatment and involves liquid nitrogen applied to the skin with a spray gun or cotton bud. The procedure is very quick, depending on the thickness and size of the lesion. The frozen skin becomes white and takes one to two minutes to thaw to normal skin temperature the dermatologist may suggest this is repeated once the skin has thawed out. Over the days following treatment, a scab will form, this will take a couple of weeks to fall off – this process cannot be hurried. Depending on the response of the tissue treated, follow up sessions may be required.
What do you need to know after treating by Cryotherapy?
Cryotherapy is usually a well-tolerated treatment, but can sometimes cause discomfort if a deep freeze is necessary. This discomfort can occur during and after the treatment and may require painkillers for the first 24 hours to relieve this, or, you may opt to have a local anaesthetic applied beforehand. Redness and blistering may occur, and it’s important to take care of the wound to avoid infection. It is important to keep the area as dry as possible and a dressing or plaster may be applied if the treated area is likely to be knocked or rubbed by clothing.
