What is a skin tag?

A skin tag is a small growth that forms on the skin. The growth hangs off the skin from a small piece of tissue called a stalk. A skin tag often grows where skin rubs against skin and causes friction. Diabetes or obesity can increase your risk for skin tags. The risk also increases with age. Skin tags are usually harmless.

What are the signs and symptoms of a skin tag?

You may have a few skin tags in the same area. This is common. A skin tag is usually the same color as your skin, or it may be a little darker. A skin tag is usually small but can be as large as 1/2 inch (1 centimeter). Skin tags usually do not cause pain, but they can cause irritation by rubbing against your clothes or jewelry. Common areas for skin tags to grow are your underarms, between folds of skin, eyelids, or inner thighs. They can also grow on your neck or other body areas.

How is a skin tag diagnosed and treated?

Your healthcare provider will be able to tell you have a skin tag by looking at it. He or she may do a biopsy (skin sample) if the skin tag looks unusual. This is to make sure it is not skin cancer. Skin tags are not always treated. The skin tag will not go away on its own, but you may not notice it or be bothered by it. You can help remove a skin tag by tying a string or dental floss around the skin tag. This will cut off the blood supply to the skin tag, and it will fall off after a few days. The following may be needed if the skin tag irritates your skin:
