Cryotherapy is a procedure that uses extreme cold (usually liquid nitrogen) to destroy abnormal or diseased tissue such as warts, skin tags, and actinic keratoses.

Liquid nitrogen is sprayed or applied with a probe, freezing the skin lesion. This causes cellular damage and eventual shedding of the treated tissue.

Mild stinging or burning during application. Tolerable.
What to Expect from the Treatment:
Redness, swelling, and blistering may follow
Lesion peels off in 5–10 days

Minimal risk of scarring or pigmentation (more in darker skin)
Who Can Do:
Any age group depending on indication. Not suitable for very large or suspicious pigmented lesions.
