Cryotherapy

What is Cryotherapy?

Cryotherapy is a minimally invasive treatment that uses extreme cold to destroy abnormal or damaged tissue. It is often used for conditions like warts, actinic keratosis, and early-stage skin cancers.

This quick, effective procedure is ideal for treating small, superficial lesions and ensures a swift recovery, allowing you to return to your daily activities with minimal interruption.

How Cryotherapy Works

Cryotherapy involves applying liquid nitrogen to the affected area through a spray or a cotton swab. The freezing temperature destroys abnormal cells, allowing healthy tissue to replace them over time.

The procedure is performed in a clinic setting and typically lasts only a few minutes.

What to Expect When Receiving Cryotherapy

• Before: Your clinician will assess the affected area and confirm that cryotherapy is the most suitable treatment. No special preparation is usually required.
• During: The liquid nitrogen is applied directly to the lesion. You may feel a brief stinging or burning sensation during the application.
• After: The treated area may blister or scab over the following days, which is normal and part of the healing process.

Risks and Complications of Cryotherapy

Cryotherapy is generally safe, but potential risks include:

• Temporary redness or swelling
• Mild discomfort during or after the procedure
• Changes in skin pigmentation, particularly in darker skin tones

Your clinician will guide you on how to care for the treated area to ensure proper healing.

How to Recover Following Cryotherapy

Healing is typically straightforward. Key recovery tips include:

• Keeping the area clean and dry.
• Avoiding picking at any blisters or scabs.
• Using over-the-counter pain relief if needed.
• Watch for signs of infection, such as increased redness or discharge, and contact your clinician if they occur.
