Skin tags are small, benign growths that appear on the skin, often in areas of friction like the neck, underarms, eyelids, and groin. These soft, flesh-colored bumps are made up of collagen fibers and blood vessels trapped inside thicker skin. While harmless, they can be bothersome due to irritation or cosmetic concerns. Skin tags are more common in adults, especially those with diabetes, obesity, or a family history of skin growths. Hormonal changes and friction from clothing or jewelry can also contribute to their formation.
