Skin Tags (Acrochordons)
Symptoms
Skin tags are small, soft, flesh-colored growths that hang from the skin by a thin stalk. They are commonly found on the neck, underarms, eyelids, and groin. While painless, they may become irritated by friction from clothing or jewelry. Some people may develop dozens of them. They are typically a few millimeters to a centimeter in size. Occasionally, they may bleed if twisted or snagged. Skin tags are benign and not harmful. They are more common with age.
Cause
Skin tags form due to friction in skin folds or from clothing. They are more common in individuals who are overweight or have diabetes. Hormonal changes, such as during pregnancy, may contribute. Genetics also plays a role—many people inherit a tendency to develop them. They are not contagious or linked to cancer. Insulin resistance may be associated with increased prevalence. Skin tags tend to develop gradually over time.
Treatment
Removal is typically done for cosmetic reasons or if the tag becomes irritated. Options include snip excision, cryotherapy, or electrocautery. Procedures are quick and usually do not require anesthesia. Insurance often does not cover treatment unless medically necessary. Over-the-counter treatments exist but may be less effective or cause irritation. Avoiding trauma to the area can prevent bleeding. Recurrence in the same spot is rare, though new tags may appear elsewhere.
