Skin Tags: What They Are and Removal Options

Skin tags are common, usually harmless skin growths that often appear in areas where skin rubs against skin or clothing. They can be small, soft, and easy to ignore, but they may become irritating when they catch on jewelry, shaving, collars, waistbands, or undergarments.

Removal is often simple in a medical setting, but it is still important to know what you are treating. A growth that looks like a skin tag may sometimes be another type of skin lesion, so a dermatologist can evaluate it before discussing the safest removal option for your skin, location, and comfort.

Quick answer

• Skin tags are soft, benign-looking growths that may hang from a small stalk or sit close to the skin.
• They often develop on the neck, eyelids, underarms, chest, groin, or other skin folds.
• Friction, age, genetics, and certain health factors can be associated with skin tag formation.
• Common professional removal options include snipping, freezing, or carefully destroying the base of the tag.
• At-home cutting, tying, or chemical removal is not recommended because it can cause irritation, bleeding, infection, scarring, or missed diagnosis.

What skin tags are

Skin tags, also called acrochordons, are small pieces of extra skin that may be flesh-colored, slightly darker, pink, or irritated-looking if they have been rubbed. Some are tiny and flat, while others hang from a narrow stalk.

They are not the same as moles, warts, cysts, or skin cancers, although some growths can look similar at first glance. That is why evaluation matters, especially when a spot is new, changing, bleeding, painful, unusually pigmented, or different from the rest of your skin.

Where skin tags commonly appear

Skin tags can form almost anywhere, but they tend to favor areas where there is movement, warmth, or friction. Common locations include:

• Neck and collar line
• Underarms
• Eyelids
• Upper chest or bra line
• Groin and inner thighs
• Under the breasts
• Other natural skin folds

Because these areas are easy to irritate with clothing, shaving, jewelry, or skin care products, even a small skin tag can become bothersome.

Common causes and triggers

There is usually not one single cause. Skin tags can be associated with several factors, and many people develop them even when they take excellent care of their skin.

• Friction: Rubbing from skin, clothing, jewelry, or shaving may contribute to irritation in areas where tags form.
• Age: Skin tags become more common in adulthood.
• Genetics: Some people seem more likely to develop them.
• Skin folds: Warm, folded areas of skin are frequent sites.
• Metabolic factors: Skin tags can be seen more often in people with certain metabolic patterns, though their presence alone does not diagnose a condition.

What you can do at home

At home, the goal is to reduce irritation rather than remove the growth yourself. Keep the area clean, avoid picking or twisting the tag, and minimize rubbing when possible. If a necklace, collar, razor, or waistband repeatedly catches the area, small changes in clothing or grooming habits may help keep it calmer until you can be evaluated.

Avoid cutting skin tags with scissors, using thread or dental floss to tie them off, applying acids, or using over-the-counter removal products near sensitive areas such as the eyes, genitals, or skin folds. These methods may cause burns, bleeding, infection, or scarring, and they do not allow a clinician to confirm what the growth is.

Professional removal options

If a skin tag is irritated, cosmetically bothersome, catching on clothing, or located in a delicate area, a dermatologist can discuss removal. The best method depends on the size, location, number of tags, skin type, and whether the growth has any features that need closer evaluation.

• Snip removal: A clinician may use sterile instruments to remove a small tag at its base.
• Freezing: Some tags may be treated with controlled cold therapy in the office.
• Electrosurgery: A dermatologist may use a precise energy-based technique to treat the base of the tag.
• Shave removal or biopsy when appropriate: If a growth is not clearly a simple skin tag, your dermatologist may recommend sampling or removal for diagnosis.

These options are typically performed in an office setting. Your clinician can explain what to expect, whether numbing may be used, and how to care for the area afterward.

When to see a dermatologist

It is worth seeing a dermatologist if a growth is new, changing, bleeding, painful, crusting, rapidly enlarging, darkly pigmented, or looks different from your other spots. You should also schedule an evaluation if it is near the eye, in the genital area, repeatedly irritated, or if you are unsure whether it is truly a skin tag.

Professional evaluation is especially important before removing a growth at home. A dermatologist can help distinguish a skin tag from a wart, mole, seborrheic keratosis, cyst, or another skin lesion that may need a different approach.

FAQ

Are skin tags dangerous?

Skin tags are commonly benign, but not every small growth is a skin tag. If a spot is changing, bleeding, painful, unusually colored, or uncertain, a dermatologist can evaluate it.

Do skin tags go away on their own?

Many skin tags remain stable. Some may become irritated or occasionally fall off after twisting or loss of blood supply, but you should not try to force this at home.

Can skin tags spread?

Skin tags are not usually considered contagious. However, other growths, such as some warts, may resemble tags, which is one reason accurate evaluation is helpful.

Will removal leave a mark?

Any skin procedure can leave temporary discoloration, texture change, or a small mark. Risk depends on the method, skin type, location, aftercare, and how the skin heals.

Can I remove a skin tag from my eyelid?

Do not attempt eyelid removal at home. The eyelid area is delicate, and a dermatologist can help determine the safest option or refer you when needed.

How do I know if it is a skin tag or something else?

You may not be able to tell with certainty from appearance alone. A dermatologist can examine the growth and recommend the right next step if removal or testing is appropriate.
