Before You Go
Questions to ask your doctor:
- Will cryotherapy remove my wart?
- How many cryotherapy treatments will I need?
- How can I make sure my skin concern doesn't return?
Pre-procedure prep for Cryotherapy: If you have a partiularly enlarged or resistant skin lesion, your dermatologist may instruct that you use salicylic acid before cryotherapy to help shrink the size of the growth.
If this preliminary step doesn't help, some of the cells may be scraped off with a scalpel.
On the day of treatment: Avoid using skin products on any areas you plan on treating.
What To Expect
Cryotherapy is performed in a doctor's office. The cold chemical is applied onto your skin by way of a spray tool, cotton swab, or metal probe.
Soon after treatment, a blister forms.
Who should do it: Cryotherapy is commonly performed by a dermatologist. Cryotherapy is unquestionably more successful when performed by an experienced, board certified physician.
Duration: The liquid nitrogen used for cryotherapy remains on a wart for less than a minute. Keloids take just 15-30 seconds. The entire appointment should take no more than 15 minutes.
How Painful Is It?
Cryotherapy is painful. A topical anesthetic may help. Residual pain can linger for about three days.
Options for anesthesia: General anesthesia is not required, but topically numbing the area beforehand is a good idea since cryotherapy can be painful.
