Liquid Nitrogen

Cosmetic use of liquid nitrogen for skin growths, also known as cryotherapy, is a procedure commonly used to remove benign skin lesions and growths. It involves applying liquid nitrogen to the affected area, resulting in freezing and subsequent removal of the unwanted skin growths. This procedure is often recommended for individuals with skin tags, warts, age spots, and other non-cancerous lesions.

Key Benefits Of Liquid Nitrogen Treatment

Non-invasive treatment for benign skin growths

Quick and relatively painless procedure

Minimal scarring compared to surgical removal

Can be performed in a clinical setting without anesthesia

Effective for a variety of skin lesions and growths

How It Works


The skin area to be treated is cleansed thoroughly. The patient’s medical history and any medications they are taking are reviewed to ensure suitability for cryotherapy.


Liquid nitrogen, which has a temperature of approximately -196°C (-321°F), is applied to the skin lesion using a cotton swab or a spray device. The liquid nitrogen freezes the water inside the cells of the lesion, causing damage to the affected tissue. This freezing process disrupts the blood supply to the lesion, leading to its eventual death and shedding from the skin’s surface.

What to Expect

During the procedure, patients may experience a brief stinging or burning sensation as the liquid nitrogen is applied. The treated area may turn white or blister immediately after cryotherapy. Over the next few days, the lesion may develop a scab or crust, which will eventually fall off, revealing new, healthy skin underneath. It is normal to experience some redness, swelling, and mild discomfort in the treated area during the healing process.


Healing time varies depending on the size and depth of the lesion treated. Most patients experience complete healing within 1 to 3 weeks after cryotherapy. It is essential to keep the treated area clean and protected from sun exposure during the healing process to prevent infection and promote optimal healing.


Is cryotherapy painful?

Discomfort during cryotherapy is usually minimal and short-lived, similar to a brief stinging or burning sensation.

How many treatments are needed?

In many cases, a single session of cryotherapy is sufficient to remove the skin growth. However, multiple treatments may be required for larger or deeper lesions.

Are there any risks or side effects?

Possible risks include scarring, pigment changes, and infection, although these are rare with proper technique and aftercare.
