In most cases, skin tags and moles are both harmless, benign skin growths that cause no pain. However, how they show up on the skin is usually very different. Moles are an overgrowth of melanocytes, otherwise known as the pigment-producing cells that give the skin its coloring. They tend to be flat and dark colored spots that may be raised; they may also be pink or light in color. Skin Tags are small, benign skin growths that appear as a soft, hanging piece of skin that may be attached by a peduncle, or stalk. Skin tags generally tend to be the same color of the individual’s skin, but also may appear more darkly colored.
