Cryotherapy is treatment using low temperature. Cryotherapy treatment refers to the removal of skin lesions by freezing them, with the most commonly used agent being liquid nitrogen. Liquid nitrogen can be used to treat a wide variety of superficial benign lesions.
The freezing procedure is best suited for removing viral warts, Actinic Keratosis (an area of sun-damaged skin found predominantly on sun-exposed parts of the body), Seborrheic Keratoses and other benign lesions.
