Fractionated cryotherapy

Cryotherapy is a commonly performed procedure in dermatology outpatient departments for destruction of pathologic tissue. It is an easy-to-perform, inexpensive, and sutureless technique and carries a minimal risk of infection. However, the procedure is associated with many complications and sequelae such as blistering, ulceration, necrosis, and permanent or longstanding pigmentary alterations. This limits its use on cosmetically sensitive sites and for indications like facial rejuvenation, particularly in people with pigmented skin.
