Cryotherapy is the process of destroying skin lesions – both pre-cancerous and benign – by freezing them with liquid nitrogen.

Used to treat Actinic Keratoses (AK), Seborrheic Keratoses (SK), warts, skin tags, moles, and other benign growths, cryotherapy is a proven, fast and effective way to eliminate skin imperfections.

At Skin Science Dermatology in Toronto, proper diagnosis and treatment of skin lesions is always performed by Dr. Geeta Yadav, a highly skilled medical dermatologist with extensive training and experience.

How Cryotherapy Works

Cryotherapy is a quick, in-office procedure that uses extreme cold to rapidly destroy unwanted tissue. Liquid nitrogen is sprayed directly onto targeted skin lesions, freezing them and causing them to slough off while leaving the surrounding area unaffected to minimize the risk of scarring. The treatment works by damaging abnormal skin cells and increasing the body’s immune response in the frozen areas.

What does cryotherapy treat?

Is cryotherapy safe?

When performed by an experienced dermatologist, cryotherapy is extremely safe and complications are rare. Treatments are quick, and normally well tolerated. As the liquid nitrogen is applied, you may feel a momentary intense cold (comparable to holding an ice cube against your skin), which should only last a few seconds. Once the area numbs, you should not experience any further discomfort.

How many cryotherapy treatments are needed?

One cryotherapy treatment is often enough to permanently remove unwanted lesions, but some lesions may need to be treated more than once. Please contact us to arrange for follow-up if you require further treatment.

Is cryotherapy right for you?

Cryotherapy is an effective solution for men and women seeking to permanently eliminate troubling skin lesions. Patients seeking cryotherapy should first consult an experienced dermatologist.

Recovery & Results

How long does it take to see results from cryotherapy?

Healing should be complete several weeks following treatment, at which point healthy new skin will replace the original lesion.

How long is the downtime after cryotherapy?

There is very little downtime associated with cryotherapy, though you may experience some pain and throbbing following your treatment. In the first 72 hours, it is normal for the treated areas to become red, swollen, and/or or blistered at the site of the freezing. As the healing process continues, a scab or crust may form, which will gradually fall off and heal fully over a period of one to four weeks. The treated area may appear red as the skin heals post-treatment. As the treatment site heals, you may wash as normal, though you should avoid scrubbing, and gently pat dry. No bandages are required, but you can apply Polysporin ointment or Vaseline one to two times per day to promote healing.
