Skin Tag Removal 

​

Liquid nitrogen is used to remove skin growths, such as warts. This treatment is known as cryotherapy. 

​

For skin growths, we apply liquid nitrogen to the skin with a spray canister or a cotton-tipped swab. Liquid nitrogen is extremely cold (approximately minus 328°F or minus 200°C). You’ll feel stinging or burning for a few minutes when it’s applied. 

​

• A blister forms on the area where liquid nitrogen contacts your skin. 

• A scab forms over the blister. It usually falls off within 2 to 4 weeks. 

 

Your skin may be tender for a few days after treatment. The treated area may be permanently scarred and:

​

• Lighter than normal skin color (hypopigmentation)

• Darker than normal skin color (hyperpigmentation)
