Skin tags are common benign skin growths. The medical name for skin tag is acrochordon. Skin tags typically occur in characteristic locations, including the base of the neck, underarms, eyelids, groin folds, and under the breasts.
The dermatology provider applies liquid nitrogen, a very cold liquid, to the growth with a spray gun. This freezes the growth.
Electrosurgery (electrocautery) involves numbing the growth with an anesthetic and using an electric current to cauterize (burn) the growth.
The cells of the skin tag are destroyed with a laser.
Cutting a skin tag off may begin with a local anesthesia. Once the area is numb, the doctor slices the skin tag away with a scalpel or a pair of sharp surgical shears and stops the blood flow to the tag.
