Cryotherapy is a common treatment used to remove skin lesions by freezing them with liquid nitrogen. At The Devonshire Clinic in London, we can offer patients cryotherapy treatments to treat a range of skin lesions.
What conditions can be treated with cryotherapy?
A whole host of benign lesions can be treated with cryotherapy. It is however most commonly used to remove actinic keratoses (pre-cancerous lesions found mainly on sun-damaged skin), viral warts, seborrhoeic keratosis and other benign lesions.
What does cryotherapy involve?
Cryotherapy can be easily performed at our dermatology clinic in Harley Street. It is usually applied using a spray gun.
Although cryotherapy can be slightly painful a local anaesthetic is not normally required. The procedure only takes a few seconds, although the exact time required depends on the thickness of the lesion being treated. Your dermatologist may repeat the process once the skin has thawed out.
What happens after cryotherapy treatment?
Immediately after cryotherapy the treated skin will be red. A scab will usually develop over the next few days which will then drop off over the next few weeks. Although in the majority of cases the treated area will eventually look normal, discolouration and scarring are possible.
Sometimes, a lesion will require several cryotherapy treatments to achieve the desired outcome.
