A skin tag (acrochordon), is a small, benign fleshy growth that hangs off the skin by a small, narrow connecting stalk. They are most often found where skin forms creases and rubs against skin: under the armpits or breasts, in the groin area, or on the eyelids or neck. Skin tags affect about 46% of the population, and are most commonly found in people who are overweight, have diabetes, and women who are pregnant.
