Skin Tags: Causes, Removal, and Prevention Tips

You reach up to scratch your neck and feel a small, soft, fleshy bump. Or you notice something hanging from your armpit that was not there before. If this sounds familiar, you have likely encountered a skin tag. They are among the most common benign skin growths, and for most people, they are nothing more than a minor cosmetic concern.

Here is everything you need to know about skin tags, from why they form to how they can be safely removed and prevented.

What Are Skin Tags?

Skin tags, medically known as acrochordons, are small, soft, noncancerous growths that develop on the surface of the skin. They typically appear as a tiny cluster of skin tissue extending outward from a thin stalk, giving them a slightly hanging appearance.

Most skin tags are between 1 and 5 millimetres in size, though some can grow to a few centimetres. They are usually the same colour as the surrounding skin, though some may be slightly darker. They feel soft to the touch and move easily when nudged.

Skin tags are extremely common. Research suggests that roughly half of all adults will have at least one in their lifetime. While they can look unsettling at first glance, they are harmless, do not spread, and pose no threat to your health.

What Causes Skin Tags?

Skin tags form when the body produces extra cells in the upper layers of the skin. They tend to develop in areas where friction occurs repeatedly, either where skin rubs against skin or where clothing or jewellery consistently rubs against skin. Common causes and contributing factors include:

• Friction: Repeated chafing between skin surfaces or from clothing, bras, collars, or jewellery is the most direct trigger for skin tag formation.
• Weight gain and obesity: Increased body weight creates more skin folds, which in turn creates more areas of ongoing friction. Obesity is a well-recognised risk factor for skin tag development.
• Insulin resistance and type 2 diabetes: Elevated insulin levels and metabolic syndrome are closely associated with the formation of multiple skin tags. If you notice several tags appearing in a short period, it may be worth checking your blood sugar levels.
• Hormonal changes: Fluctuations in hormones during pregnancy or due to hormonal imbalances can encourage skin tag growth.
• Age: Skin tags become more common as you get older. They are rarely seen in children and most often appear in middle-aged and older adults.
• Genetics: A family history of skin tags increases your likelihood of developing them.
• HPV: Some studies have suggested a link between certain strains of the human papillomavirus and skin tag formation, though research in this area is ongoing.

What Are the Symptoms of Skin Tags?

In most cases, skin tags cause no symptoms at all. They are not itchy, painful, or inflamed unless they are being repeatedly irritated. Many people only notice them when they catch a glimpse in the mirror or feel them while washing or dressing.

However, in some situations, skin tags can cause mild discomfort. If a tag is located in an area of frequent friction, such as where a necklace rests or where clothing rubs, it can become irritated, sore, or bleed slightly. A skin tag that catches on jewellery or a shirt collar and twists can also cause a brief, sharp pain.

If a growth is bleeding, growing rapidly, changing colour, or causing significant pain, it should be evaluated by a doctor to rule out other skin conditions.

Who Is More Likely to Develop Skin Tags?

While anyone can develop skin tags, some people are at higher risk:

• Adults over the age of 40, as skin tags become progressively more common with age
• People who are overweight or living with obesity, due to increased skin folds and friction
• Individuals with type 2 diabetes or insulin resistance
• Pregnant women, due to hormonal changes and weight gain
• People with a family history of skin tags
• Those with certain skin conditions such as Birt-Hogg-Dubé syndrome
• Individuals who regularly wear tight clothing, jewellery, or accessories that rub against the skin

Common Areas Where Skin Tags Appear

Skin tags tend to develop in areas where friction is ongoing or where warmth and moisture accumulate. The most common locations include:

• Neck: Particularly where necklaces sit or where collars rub
• Armpits: A frequent site due to skin-on-skin contact and movement
• Groin and inner thighs: Warm, moist areas prone to chafing
• Under the breasts: Common in women due to bra friction
• Eyelids: Less common but possible, and requiring particular care during removal
• Genitals: Can occur in both men and women

Are Skin Tags Dangerous?

No. Skin tags are a benign skin growth and are completely noncancerous. They do not turn into cancer and do not increase your risk of developing any serious skin condition.

That said, it is worth being cautious if a growth is changing in size, shape, or colour, or if it bleeds without injury. Not every bump that resembles a skin tag is one. Warts, moles, and, in rare cases, skin cancer can mimic the appearance of a skin tag. A qualified healthcare provider can tell the difference after a brief examination.

If you are unsure about any growth on your skin, getting it checked is always the right decision.

How Skin Tags Are Diagnosed

Diagnosis is straightforward. Your healthcare provider will examine the growth visually and ask about your medical history, including any conditions such as diabetes or hormonal disorders that might be contributing. No tests are typically needed to confirm a skin tag diagnosis.

If your doctor suspects the growth might be something other than a skin tag, such as a wart or an unusual mole, they may perform a biopsy, taking a small sample of tissue for laboratory analysis. This is rarely necessary but ensures an accurate diagnosis when doubt exists.

Skin Tag Removal Options

Skin tags do not require removal for medical reasons. However, if a tag is bothering you cosmetically, causing irritation, or getting caught on clothing or jewellery, removal is a straightforward option.

It is important to have skin tags removed by a qualified healthcare professional, not at home. Over-the-counter kits and home remedies such as tea tree oil or apple cider vinegar carry real risks, including infection, scarring, excessive bleeding, incomplete removal, and the danger of mistakenly treating something that is not a skin tag at all.

Professional removal options include:

Excision

The skin tag is snipped off at its base using surgical scissors or a scalpel. This is a quick, precise method and is one of the most commonly used techniques for skin tags of all sizes.

Cryotherapy

Liquid nitrogen is applied to the skin tag to freeze and destroy the tissue. The tag typically falls off within a few days to a week following the procedure. This is the same technique used for wart removal.

Electrocautery

A small electric current is used to burn off the skin tag. This method also seals the blood vessels at the base simultaneously, reducing the risk of bleeding.

Laser Treatment

Laser energy targets and destroys the skin tag tissue precisely. This option is particularly useful for tags in sensitive areas such as around the eyes.

All these procedures are performed in a clinical setting, usually take only a few minutes, and involve minimal discomfort. Local anaesthetic may be used to numb the area beforehand.

Aftercare Tips Post Skin Tag Removal

Taking care of the treated area properly after removal helps it heal quickly and minimises the risk of infection or scarring:

• Keep the area clean: Gently clean the treated spot with mild soap and water as directed by your provider.
• Avoid picking or scratching: Allow any scab that forms to fall off naturally. Picking at it can cause scarring or introduce infection.
• Apply prescribed ointment if recommended: Your provider may suggest an antibiotic cream or healing ointment for the first few days.
• Protect from sun exposure: Newly healed skin is sensitive to UV radiation. Keep the area covered or apply sunscreen once healing is complete.
• Watch for signs of infection: Redness, increasing swelling, pus, or fever after a removal procedure should prompt a call to your doctor.
• Avoid friction on the area: If the tag was in a spot prone to rubbing, take steps to protect it with loose clothing or a small dressing while it heals.
• Attend any recommended follow-up: Your provider may want to check the site to ensure it has healed properly.

Prevention Tips to Reduce Skin Tag Formation

While you cannot eliminate all risk of developing skin tags, certain lifestyle habits can significantly reduce their formation:

• Maintain a healthy body weight: Fewer skin folds means less friction, which is one of the most effective ways to reduce skin tag formation. Managing obesity is particularly important, as it is one of the strongest risk factors.
• Wear loose, soft clothing: Tight waistbands, collars, and synthetic fabrics that chafe repeatedly create ideal conditions for skin tags to develop.
• Choose jewellery carefully: Necklaces and bracelets that constantly rub against the same area of skin can trigger growths over time. Opting for smoother designs and occasionally giving skin a rest from jewellery helps.
• Keep skin folds dry: Moisture trapped in skin folds adds to irritation. Gentle drying after bathing and using a light talc-free powder where appropriate can help.
• Manage blood sugar: If you have diabetes or insulin resistance, keeping your blood glucose well controlled can reduce the tendency to develop new skin tags.
• Stay active: Regular physical activity supports a healthy weight and metabolic health, both of which are linked to a lower risk of skin tag formation.
• Practice good skin hygiene: Keeping skin clean reduces ongoing irritation that can contribute to benign skin growth over time.

When to See a Doctor

For most people, a skin tag is nothing to worry about and can be left alone indefinitely. However, there are certain situations where a medical evaluation is advisable.

See a doctor if a growth is changing in size, shape, or colour over a short period. Seek attention if the tag bleeds without being caught on anything, causes persistent pain, or is accompanied by inflammation of the surrounding skin. You should also consult a doctor if you are unsure whether a growth is actually a skin tag, or if you are developing many new skin tags in a short span of time, as this may warrant screening for insulin resistance or diabetes.

Never attempt to cut, tie off, or chemically treat a skin tag at home. The risks far outweigh the convenience.

Frequently Asked Questions About Skin Tags

Why Do People Suddenly Get Skin Tags?

Skin tags can appear to develop suddenly, but they typically form gradually over time as a result of repeated friction on the skin. Triggers such as weight gain, hormonal changes during pregnancy, or worsening insulin resistance can accelerate their development. A sudden increase in the number of skin tags, particularly in adults, may also point to an underlying metabolic issue worth investigating with a healthcare provider.

Are Skin Tags a Warning?

In most cases, skin tags are not a warning sign of anything serious. They are a benign skin growth and are very common in the general population. However, developing many skin tags, especially if they appear suddenly and in clusters, can sometimes be associated with insulin resistance, type 2 diabetes, or, rarely, certain genetic syndromes. If you notice a sudden increase in skin tags, it is reasonable to have a blood sugar check and a general health review.

Are Skin Tags a Sign of Diabetes?

Skin tags alone are not a confirmed sign of diabetes, but there is a recognised association between the two. People with insulin resistance or type 2 diabetes are more likely to develop multiple skin tags, possibly because elevated insulin levels stimulate the growth of skin cells. If you have multiple skin tags and have not been screened for diabetes recently, it is worth discussing this with your doctor. A simple blood test can provide clarity.

Can Skin Tags Fall Off on Their Own?

Yes, some skin tags do fall off on their own, particularly if their blood supply is disrupted by twisting or prolonged friction. This is more likely with very small tags. However, it is not something that happens predictably or consistently. Larger tags are less likely to detach on their own. If a skin tag does fall off naturally, the area usually heals without issue, but any bleeding or signs of infection should prompt a medical review.

Do Skin Tags Grow Back After Removal?

If a skin tag is fully removed by a healthcare professional, it is unlikely to grow back in the same spot. However, the conditions that caused it, such as ongoing friction, weight, or metabolic factors, remain. This means new skin tags can develop in the same or nearby areas over time. Addressing the underlying causes through lifestyle changes gives you the best chance of reducing future occurrences.

Why Do Skin Tags Appear on the Neck?

The neck is one of the most common sites for skin tags because it experiences consistent friction from shirt collars, necklaces, and everyday movement. The skin around the neck also has natural folds that create friction zones. People who wear jewellery daily are particularly prone to developing neck skin tags. Switching to looser necklines and giving the skin regular breaks from accessories can help reduce recurrence in this area.

Are Skin Tags Contagious?

No. Skin tags are not contagious and cannot be passed from person to person through touch or close contact. They are the result of friction and internal factors like genetics and metabolism, not an infectious process. There is no need to avoid contact with someone who has skin tags, and having them does not put others around you at any risk.

Does Removing a Skin Tag Hurt?

Professional skin tag removal is generally well tolerated. The area is typically numbed with a local anaesthetic before the procedure, so you should feel minimal discomfort during removal itself. After the anaesthetic wears off, there may be mild soreness, tenderness, or a stinging sensation for a day or two, which usually resolves quickly. Most people are surprised by how straightforward and comfortable the experience is when carried out by a skilled professional.
