What is cryotherapy?

Cryotherapy is the use of liquid nitrogen to freeze the skin in order to treat benign and malignant lesions. It is often used to treat warts, seborrheic keratoses, lentigenes (or “age spots”), pre-cancerous actinic keratosis and superficial non-melanoma skin cancers. The procedure basically causes a superficial “freeze-burn” that will result in some redness then scaling and crusting in the area. Cryotherapy risks include blister formation, hypopigmentation and scarring in the area.
