Skin tags are common skin growths that can appear on different parts of the body, including the neck, eyelids, underarms and groin. Although they are generally harmless, their appearance can sometimes cause discomfort or cosmetic concerns, particularly when they develop in areas exposed to regular friction.

It’s important to understand what causes skin tags, how to identify them and when they require medical attention because this can help you make informed decisions about your skin health. While most skin tags do not require treatment, some may benefit from removal.

What Are Skin Tags?

Skin tags, medically known as acrochordons, are small, soft and usually harmless growths that develop on the skin’s surface. They are typically flesh-coloured or slightly darker and often appear as small pieces of tissue attached to the skin by a narrow stalk.

Most skin tags measure just a few millimetres, although some can grow larger. They commonly develop in areas where skin folds or rubs against itself, such as the neck, armpits, eyelids and groin.¹

Skin tags consist of collagen fibres, blood vessels and surrounding skin tissue. They are noncancerous and generally do not cause pain unless they become irritated through friction, scratching or accidental injury.

Are Skin Tags Common and Should You Be Concerned?

Skin tags are extremely common, particularly among middle-aged and older adults. They can develop in people of all skin types and are not usually a cause for concern.

Most skin tags are painless and do not affect overall health. However, they may become uncomfortable when rubbed by clothing, jewellery or other skin surfaces. Some people also choose removal because they dislike their appearance.

Although skin tags are generally harmless, not every small skin growth is necessarily a skin tag. Growths that change in appearance, bleed repeatedly, become painful or grow rapidly should be examined by a dermatologist.

What Is the Reason for Skin Tags?

The exact reason why skin tags develop is not fully understood. However, several factors are associated with their formation. These include friction, hormonal changes, ageing, genetics and certain metabolic conditions.

Common Causes and Risk Factors of Skin Tags

One of the most commonly recognised contributing factors is repeated friction.² When skin rubs against skin or clothing, irritation may contribute to the development of skin tags, particularly in areas with natural folds.

Other associated risk factors include:

• Ageing: Skin tags become more common as people get older.
• Obesity: Additional skin folds can increase friction between skin surfaces.
• Insulin resistance: Skin tags are associated with insulin resistance and metabolic conditions.
• Diabetes: People with type 2 diabetes may be more likely to develop multiple skin tags.
• Genetics: A family history of skin tags may increase susceptibility.
• Pregnancy: Hormonal and physical changes during pregnancy may contribute to their development.

These factors do not mean that everyone with skin tags has an underlying medical condition. However, developing numerous new skin tags may be a reason to discuss metabolic health with a doctor.

Does Friction, Hormonal Changes, or Genetics Cause Skin Tags?

Friction is considered an important contributing factor because skin tags frequently appear in areas where skin surfaces repeatedly touch.

Hormonal changes may also influence their development. For example, some pregnant women notice new skin tags as their bodies experience hormonal changes and increased skin friction.

Genetics may play a role as well. People with close relatives who develop skin tags may have a greater likelihood of experiencing them.

However, these factors are associated with the formation of skin tags, rather than being the definitive causes in every individual.

Who Is More Likely to Develop Skin Tags?

Although anyone can develop skin tags, certain groups have a higher likelihood of experiencing them.

These include:

• Middle-aged and older adults.
• People who have obesity or excess skin folds.
• Individuals with type 2 diabetes or insulin resistance.
• Pregnant women.
• People with a family history of skin tags.

Maintaining general skin health and managing underlying health conditions can be beneficial, although there is no guaranteed way to prevent skin tags.

Where Do Skin Tags Commonly Appear on the Body?

Skin tags can develop almost anywhere, but they are particularly common in areas where skin folds, rubs together or experiences repeated friction.

Some locations may require additional attention because the skin is delicate or because other medical conditions can produce similar-looking growths.

Skin Tags on Neck: Causes, Symptoms, and Treatment

Skin tags on the neck are among the most common types. They often develop around the sides, back or front of the neck, particularly in areas where clothing, necklaces or skin surfaces create friction.

These growths are usually small, soft and skin-coloured or brown. They may appear individually or in clusters.

Most neck skin tags are harmless. However, repeated rubbing from collars, jewellery or shaving can cause irritation, redness or occasional bleeding.

If a skin tag becomes uncomfortable or affects your appearance, a dermatologist can assess it and discuss suitable removal options.

Skin Tags on Eyelid: Why Do They Develop and Are They Dangerous?

Skin tags on eyelids can develop because of natural skin folds and repeated friction. They may appear as small, soft growths near the upper or lower eyelid.

Although most eyelid skin tags are harmless, their location makes professional assessment particularly important. Larger growths may interfere with blinking or vision, while removal near the eye requires careful technique.

Avoid attempting to cut, freeze or apply chemical products to an eyelid growth. Consult a dermatologist or an ophthalmologist if a growth affects your eyesight or causes irritation.

Skin Tags in Armpit: Causes and Ways to Manage Them

Skin tags in armpit areas are common because the underarms experience frequent skin-to-skin contact, moisture and friction.

They may develop as small, soft growths that are usually painless. However, shaving, tight clothing and repeated rubbing can irritate them.

To manage underarm skin tags:

• Avoid shaving directly over the growth.
• Choose comfortable clothing that reduces friction.
• Avoid scratching or pulling at the affected area.
• Consult a dermatologist if the growth becomes painful or bleeds.

Professional removal may be considered if the skin tag repeatedly becomes irritated.

Anal Skin Tag: Symptoms, Causes, and Treatment Options

Anal skin tags are small, soft pieces of excess skin that develop around the opening of the anus. They are generally benign and may appear as flesh-colored or slightly darker growths.

They can sometimes develop following irritation, inflammation or changes associated with previous haemorrhoids.

Most anal skin tags do not cause significant symptoms. However, some people experience discomfort during cleaning, itching or irritation.

It is important not to assume that every growth around the anus is a skin tag. Haemorrhoids, warts and other conditions can produce similar symptoms.

A doctor can examine the area, determine the cause and recommend appropriate treatment if necessary. Removal should only be considered after proper medical assessment.

Vaginal Skin Tags: What Causes Them and When to Seek Medical Advice?

Vaginal skin tags are commonly used to describe small, soft growths around the external genital area, particularly the vulva and labia.

Technically, these growths develop on external skin rather than inside the vaginal canal. They are usually harmless and may be associated with friction, pregnancy or natural changes in the skin.

However, genital skin tags can sometimes resemble genital warts or other vulvar conditions. A medical examination is important if you notice a new growth, changes in its appearance, unusual discharge, pain or bleeding.

Avoid using over-the-counter skin tag removers or home remedies on sensitive genital tissue. A healthcare professional can confirm the diagnosis and discuss safe treatment options.

Are Skin Tags Harmful or a Sign of an Underlying Health Problem?

In most cases, skin tags are harmless and do not develop into cancer. They are considered benign skin growths and generally do not require medical treatment.

However, multiple skin tags have been associated with metabolic conditions such as insulin resistance, obesity and type 2 diabetes.³ Having skin tags does not automatically mean you have one of these conditions, but a sudden increase in their number may justify a medical consultation.

It is also important to distinguish skin tags from other skin abnormalities that may require different treatment.

How to Differentiate Skin Tags from Warts and Moles

Skin tags, warts and moles can sometimes look similar, particularly when they are small. However, they have different characteristics.

• Skin tags: Usually soft, smooth and attached to the skin by a narrow stalk. They are commonly flesh-coloured or slightly darker.
• Warts: Often have a rough or uneven surface and may feel firmer than skin tags. Some are caused by human papillomavirus (HPV).
• Moles: Usually appear as flat or raised spots with varying shades of brown, black or pink.

Other growths, including seborrheic keratoses and certain skin tumours, can also resemble skin tags.

A dermatologist can examine an unusual growth and determine whether it is a skin tag or another skin condition.

When Should You Be Concerned About a Skin Tag?

Although most skin tags are harmless, certain changes should not be ignored.

Consider seeking medical advice if a skin growth:

• Increases in size rapidly.
• Changes colour or shape.
• Becomes painful or persistently irritated.
• Bleeds repeatedly.
• Develops unusual swelling or inflammation.
• Appears in large numbers over a short period.

You should also seek an examination if you are uncertain whether the growth is actually a skin tag.

How Are Skin Tags Diagnosed?

Skin tags are usually diagnosed through a physical examination. A dermatologist or healthcare professional will assess the growth’s appearance, texture, size and location.

In most cases, additional testing is unnecessary because typical skin tags have recognisable characteristics.

However, medical evaluation is particularly important when a growth looks unusual or resembles another skin condition.

What to Expect During a Skin Examination

During an examination, your healthcare provider may:

1. Ask when you first noticed the growth.
2. Check whether it has changed in size, colour or appearance.
3. Examine its texture and attachment to the skin.
4. Ask about irritation, bleeding or discomfort.
5. Review relevant medical and family history.

The examination is generally straightforward and does not require special preparation.

When Is a Biopsy Recommended?

A biopsy may be recommended when the healthcare provider cannot confidently identify the growth through a physical examination.

During this procedure, a small tissue sample is collected and sent to a laboratory for examination.

A biopsy can help distinguish a typical skin tag from other skin conditions, including certain abnormal or cancerous growths.

It is not routinely necessary for ordinary skin tags, but it can provide additional information when the diagnosis is uncertain.

Skin Tag Removal: What Are the Available Treatment Options?

Most skin tags do not need removal unless they cause irritation, discomfort or cosmetic concerns.

When removal is appropriate, a dermatologist can recommend a suitable procedure based on the growth’s size, location and characteristics.

Common professional skin tag removal methods include cryotherapy, surgical excision and electrocautery.

Cryotherapy (Freezing)

Cryotherapy involves applying a very cold substance, usually liquid nitrogen, to freeze and destroy the skin tag.

The treated tissue gradually forms a blister or scab, which eventually falls away during the healing process.

This method is commonly used for suitable skin tags, although multiple treatments may sometimes be required.

Surgical Excision

Surgical excision involves removing the skin tag using sterile surgical scissors or a blade.

A healthcare professional may apply local anaesthesia to reduce discomfort before the procedure.

This method is often suitable for larger growths or skin tags that require precise removal. The treated area may experience minor bleeding or temporary tenderness.

Electrocautery (Burning)

Electrocautery uses controlled electrical energy to destroy the skin tag and help control bleeding.

The procedure is performed by a trained healthcare professional and may involve local anaesthesia.

A small scab generally forms over the treated area before the skin heals.

The choice between these procedures depends on individual circumstances and the dermatologist’s assessment.

Can You Remove Skin Tags at Home Safely?

It may be tempting to remove a skin tag at home using scissors, threads, creams or household remedies. However, these methods can cause complications.

Cutting or pulling a skin tag can lead to bleeding, infection and scarring. Applying substances such as apple cider vinegar or essential oils may also irritate or damage surrounding skin.

Over-the-counter products marketed for removing skin tags may cause burns, irritation or permanent scarring. The FDA has also raised concerns about unproven skin lesion removal products.

For these reasons, professional assessment and removal are generally safer than attempting home treatment.

Never attempt to remove growths near the eyes, genitals or anus yourself.

When Should You Visit a Skin Tag Removal Doctor?

Consulting a qualified healthcare professional is recommended when a skin tag causes discomfort, repeatedly becomes irritated or affects your daily activities.

A skin tag removal doctor can confirm the diagnosis, assess potential risks and recommend the most appropriate treatment.

Signs That You Need Professional Skin Tag Removal

Consider visiting a dermatologist if:

• A skin tag repeatedly catches on clothing or jewellery.
• The growth becomes painful or starts bleeding.
• An eyelid growth interferes with vision.
• A growth develops around the genital or anal area.
• You notice several new growths within a short period.
• You are unsure whether the growth is actually a skin tag.

Even when removal is not medically necessary, a dermatologist can discuss cosmetic treatment options.

How to Choose the Right Dermatologist

Choosing an experienced dermatologist is important, particularly when skin tags develop in sensitive areas.

Look for a qualified medical professional who:

• Has appropriate dermatology training and credentials.
• Has experience with skin lesion diagnosis and removal.
• Explains the available treatment options.
• Discusses possible complications and scarring.
• Provides clear aftercare instructions.

For growths around the eyes, genital area or anus, seek a clinician with relevant experience or an appropriate specialist referral.

What to Expect After Skin Tag Removal

Recovery depends on the removal method, the size of the growth and its location.

You may experience mild redness, tenderness, swelling or scabbing around the treated area. These effects generally improve as the skin heals.

Your dermatologist may recommend:

• Keeping the treated area clean.
• Following instructions about wound care and dressings.
• Avoiding unnecessary friction.
• Not picking or scratching the healing skin.
• Watching for signs of infection.

Contact your dermatologist if you experience increasing pain, spreading redness, pus, fever or persistent bleeding.

Frequently Asked Questions

Q. Do Skin Tags Go Away on Their Own?

A. Some skin tags may fall off naturally, particularly if their blood supply becomes restricted. However, many remain on the skin unless removed. They generally do not require treatment if they are harmless and cause no discomfort.

Q. Can Skin Tags Grow Back After Removal?

A. A completely removed skin tag usually does not grow back in the same spot. However, new skin tags can develop in other areas because the underlying factors contributing to their formation may remain.

Q. Are Skin Tags Contagious?

A. No. Ordinary skin tags are benign skin growths and are not contagious. They do not spread through physical contact or sharing personal belongings. However, some conditions that resemble skin tags, such as genital warts, can be contagious.

Q. Can Skin Tags Be Prevented?

A. There is no guaranteed way to prevent skin tags. However, reducing skin friction, wearing comfortable clothing and managing relevant health conditions may help address some associated risk factors.

Q. Does Removing a Skin Tag Hurt?

A. Skin tag removal usually involves minimal discomfort. Depending on the procedure, a healthcare professional may use local anaesthesia to numb the area. Some tenderness or irritation may occur during the healing process.
