Skin tags are very common and generally occur after midlife, and can appear anywhere on the skin. A skin tag is a small raised piece of skin which may also have a stalk, and looks like a small piece of soft, hanging skin. Under the microscope, skin tags are thicker skin containing clusters of collagen and blood vessels. It is believed that skin tags form as a result of skin rubbing against skin. That’s the reason why skin tags are most often found around skin creases and folds, and where skin rubs against clothing. Common areas include the neck, eyelids, under arm area, under the breasts and the groin.
Skin tags can be removed by an ablative laser. I prefer to use an Erbrium Yag instead of a CO2 laser, as there is lower risk of post inflammatory hyperpigmentation.
