How to Freeze Skin Moles

According to MayoClinic.com, the skin's pigment-producing melanocytes usually distribute color evenly throughout the surface of your skin. Sometimes, however, clusters of pigmented cells develop, resulting in dark spots commonly called moles. Moles can appear in a variety of colors ranging from red to dark brown, and can be flat or protruding, round or oval. While they are generally harmless, some people may want to remove them for cosmetic reasons. Also, some protruding moles may be prone to irritation if they are located in an area where they are frequently rubbed by clothing or nicked by razors. Cryotherapy uses liquid nitrogen to freeze unwanted skin lesions 1. The procedure generates few side effects and can be completed quickly in your doctor's office.

Consider the side effects associated with cryotherapy 1. Immediate side effects may include swelling or blistering of the treatment area, and on rare occasions, infection can occur. The treated area may also differ in color from the surrounding skin, particularly with darker skinned individuals. The discoloration may fade over time, or it may be permanent. Also, numbness in the area can occur if a superficial nerve is frozen. If this occurs, sensation to the affected area returns in a few months.
