Skin tags are common benign growths. It is unclear why they develop, but they tend to occur in areas of friction or where skin rubs against other skin, such as in the armpits or in the neck folds. Occasionally, skin tags can become red or even bleed if they are traumatized by clothing or jewelry. If this occurs, they can be removed using liquid nitrogen or a sharp sterile tool. Skin tags can also be removed for cosmetic reasons. The choice of treatment depends on the size and number of skin tags to be removed. There is little downtime associated with treatments, but there may be some redness followed by scabbing at the treatment sites.
