Cryotherapy

Cosmetic Removal of Skin Lesions

What is Cryotherapy?

Cryotherapy (also known as cryosurgery or cryoablation) is a technique that uses extremely cold liquid, most commonly Liquid Nitrogen, to freeze skin surface lesions. This minimally invasive process safely destroys and removes unwanted skin imperfections.

The procedure involves applying the cryogen to the lesion. The extreme cold freezes the targeted tissue, causing cell walls to rupture and the cells to break down. The frozen skin becomes white, and as it thaws, the body begins its natural healing process, clearing away the treated tissue over the following weeks. The pain is typically mild and short-lived, meaning a local anesthetic is not usually required.

What is Cryotherapy Used For?

Cryotherapy is highly effective for the removal of common, benign lesions, including:

Actinic keratoses
Seborrhoeic keratoses
Viral warts

Molluscum contagiosum
Skin tags

Treatment Schedule and Aftercare

Arrange Your Consulation

Before & During Treatment

Consultation: A medical consultation is required to assess the lesion and determine suitability for removal.
Anesthesia: Local anesthetic (cream or injection) can be applied if necessary, though pain is usually mild and brief.
Duration: The procedure itself lasts only a matter of seconds, depending on the size and thickness of the lesion.
Process: The skin freezes white, takes a minute or two to thaw, and the process may be repeated once thawed.

Aftercare and What to Expect

Initial Reaction:The treated area may show redness, swell, or blister (containing clear or bloody fluid, which is harmless) within a few hours.
Scab Formation: A scab will form after a few days; do not pick the scab as this encourages scarring.
Immediate Care: Keep the area dry for 24 hours. Afterward, wash gently and apply petroleum jelly (e.g., Vaseline®) daily.
Full Healing: A scab takes a few weeks to fall off (longer on the legs). In most cases, the treated area will look like normal skin, though changes in colour are possible.
