Skin tags are small, soft growths of skin that often develop in areas of the body where the skin folds or experiences friction. Though typically harmless, skin tags are a common cosmetic concern that many people encounter throughout their lives. While they are not dangerous, understanding their causes, prevention methods, and treatment options can help individuals manage and remove them effectively.

In this comprehensive guide, we will explore what causes skin tags, how they can be prevented, and the various treatments available. Whether you’re simply curious about these benign growths or are considering removal options, this article will provide you with a wealth of information to make informed decisions.

Understanding Skin Tags – How to Identify a Skin Tag

What are Skin Tags?

Skin tags, medically known as acrochordon, are small, benign (non-cancerous) growths of skin that often appear as soft, flesh-colored or slightly darker bumps. They typically range in size from a few millimeters to about 2.5 cm (1 inch) in diameter. Skin tags are often attached to the skin by a small stalk-like structure called a peduncle, and they can vary in appearance from smooth to slightly wrinkled.

The most common locations for skin tags are areas where skin folds or experiences friction, such as the neck, underarms, eyelids, groin, and under the breasts. While they can appear on almost any part of the body, they tend to develop in areas where clothing, jewelry, or skin rub against one another.

Why Are They Called Skin Tags?

The name “skin tag” comes from the appearance of the growth, which often resembles a small tag or flap of skin. The term “acrochordon” is derived from the Greek words “acro-“ (meaning “extremity” or “point”) and “chordon” (meaning “cord” or “string”), referencing the appearance of these growths, often on the skin’s extremities or areas of friction.

Who is more likely to get Skin Tags? – Prevalence and Common Populations Affected

Skin tags are incredibly common and affect a large portion of the population. It’s estimated that around 25% of adults may develop skin tags at some point in their lives. Although they can appear at any age, skin tags are most commonly seen in middle-aged adults, especially those aged 40 and older.

Certain factors increase the likelihood of developing skin tags, including genetics, obesity, and hormonal changes. People with diabetes, in particular, have a higher incidence of skin tags, likely due to factors such as insulin resistance and skin friction. Overall, anyone can develop skin tags, but they are particularly common in individuals who are overweight or have certain medical conditions.

What Causes Skin Tags?

Understanding the causes of skin tags is key to both prevention and treatment. Several factors contribute to the development of skin tags, including genetic predisposition, hormonal fluctuations, friction, and underlying health conditions.

Genetics

Genetics play a significant role in the development of skin tags. Studies have shown that skin tags tend to run in families, suggesting that a hereditary predisposition may be at play. If a close relative, such as a parent or sibling, has skin tags, you may be more likely to develop skin tags as well. Although the exact genetic mechanisms are not fully understood, this familial tendency indicates that skin tags may be partially inherited.

Hormonal Changes

Hormonal fluctuations are another common cause of skin tags. Pregnancy is a notable example of a period in life when women are more likely to develop skin tags. During pregnancy, hormone levels (particularly estrogen) rise, which can lead to an increase in skin tag formation. Additionally, hormonal changes related to conditions like polycystic ovary syndrome (PCOS) and menopause may also trigger the development of skin tags.

Hormonal imbalances associated with conditions like obesity and diabetes can further increase the likelihood of developing skin tags. This is due to changes in insulin levels and other hormones that affect skin health and growth patterns.

Friction and Skin Irritation

One of the most common contributing factors to skin tag formation is friction or repetitive skin irritation. Areas where skin rubs against itself, such as the neck, armpits, groin, and under the breasts, are prime locations for skin tags to form. This is because continuous rubbing or friction can cause skin cells to grow abnormally, leading to the formation of a skin tag.

People who wear tight clothing, jewelry, or have skin-on-skin contact in areas like the thighs and groin are particularly susceptible to developing skin tags. Weight gain can also increase the amount of friction in these areas, which is why skin tags are more common in individuals with higher body weight.

Age

As individuals age, their skin naturally undergoes changes that make it more prone to developing skin tags. The skin becomes thinner and less elastic, and the growth of new skin cells can become less regulated. These age-related changes may contribute to the formation of skin tags, especially in areas that experience constant friction or irritation. As mentioned, skin tags are most commonly found in people over the age of 40.

Skin Conditions and Medical Factors

Certain medical conditions can increase the likelihood of developing skin tags. Obesity and metabolic syndrome are two of the most common risk factors. In these conditions, insulin resistance and elevated blood sugar levels can affect skin health and lead to the growth of skin tags.

Diabetes, in particular, is associated with a higher prevalence of skin tags. Insulin resistance and elevated blood glucose levels create an environment in which skin cells may grow abnormally, leading to skin tags. Other conditions that may be linked to skin tags include high blood pressure and hormonal disorders.

Underlying Factors and Possible Mechanisms

While the exact mechanisms behind skin tag formation remain unclear, there are a few theories explaining how skin tags develop. One prominent hypothesis is that skin tags form when a cluster of collagen (a structural protein in the skin) and blood vessels grow inside a small area of the skin. This growth may be triggered by factors such as friction, hormonal changes, or insulin resistance.

Skin tags are also thought to result from the skin’s response to injury or irritation. When the skin is constantly irritated or rubbed, it may initiate a growth response, leading to the formation of a benign growth like a skin tag.

How to Prevent Skin Tags?

While it may not be possible to prevent skin tags entirely, there are several steps you can take to reduce your risk. Most prevention methods focus on minimizing friction, managing underlying health conditions, and promoting healthy skin.

Managing Friction and Skin Irritation

Since friction is a leading cause of skin tags, minimizing skin irritation is a key preventative measure. To reduce friction in high-risk areas, consider:

• Wearing loose-fitting clothing: Tight clothes or jewelry can rub against your skin and create constant irritation, so choose loose-fitting clothing that doesn’t press against your skin.
• Avoiding excessive skin-to-skin contact: If you have areas where skin rubs against skin (such as the thighs or underarms), try to prevent this by using talcum powder or anti-chafing creams to reduce friction.
• Opting for soft fabrics: Choosing fabrics that are gentle on the skin can help prevent friction-related skin irritation.

Lifestyle Changes for Prevention

Managing your weight and maintaining a healthy lifestyle can help reduce your risk of developing skin tags. The following lifestyle changes can be beneficial:

• Maintaining a healthy weight: People who are overweight or obese are more prone to skin tags due to increased friction in areas like the neck, groin, and underarms. Regular exercise and a balanced diet can help reduce the risk.
• Managing blood sugar levels: If you have diabetes or insulin resistance, managing your blood sugar through diet, exercise, and medication can help prevent the formation of skin tags.
• Staying hydrated: Keeping your skin hydrated with moisturizers or drinking plenty of water can help maintain skin health and reduce irritation.

Skincare Tips

Good skincare practices can help prevent the development of skin tags, particularly in areas that are prone to friction. Some tips include:

• Cleansing and moisturizing regularly: Keeping your skin clean and moisturized can prevent dryness and irritation, which may contribute to skin tag formation.
• Using sunscreen: Protecting your skin from excessive sun exposure can help prevent damage and irritation that may lead to the development of skin tags.

Recognizing Risk Factors Early

Being aware of the factors that increase your risk of skin tags—such as obesity, diabetes, and hormonal changes—can help you take proactive steps to manage these risk factors. Early intervention and lifestyle modifications may reduce the likelihood of developing skin tags in the future.

Can Skin Tags Be Prevented Entirely?

Unfortunately, skin tags cannot always be entirely prevented, especially if they are hereditary. However, by managing risk factors like friction, weight, and hormonal imbalances, you can lower your chances of developing them.

How to get rid of Skin Tags? – Treatment Options for Skin Tags

While skin tags are typically harmless and don’t require medical treatment, many people choose to remove them for cosmetic reasons or because they become irritated due to friction. There are various treatment options available, ranging from at-home remedies to professional medical procedures.

Non-Surgical Treatments

For many individuals, non-surgical treatments are effective in managing or removing skin tags. These methods can often be performed at home or with over-the-counter products.

Over-the-Counter Removal Products

There are several over-the-counter products designed to remove skin tags, usually through a process of freezing or drying out the growth. These products are generally available in pharmacies and can be applied directly to the skin tag. Some common types include:

• Cryotherapy Kits: These products use liquid nitrogen to freeze the skin tag off. Cryotherapy works by freezing the blood supply to the skin tag, which causes it to fall off after a few days. While this treatment is generally effective, it’s essential to follow the instructions carefully to avoid damaging the surrounding skin.
  
• Topical Skin Tag Removal Creams: These creams work by drying out the skin tag, causing it to shrivel and eventually fall off. Some products may require multiple applications over a few weeks for full effectiveness.
  

While these products are convenient and relatively inexpensive, their success may vary based on the size, location, and number of skin tags. Some people may experience irritation or scarring if the products are not used properly.

Natural Remedies

Many people turn to natural remedies for skin tag removal, although the effectiveness of these treatments is anecdotal and not scientifically proven. Some popular home remedies include:

• Tea Tree Oil: Tea tree oil is known for its anti-inflammatory and antimicrobial properties. Some individuals apply a few drops of tea tree oil to the skin tag daily, which may gradually dry it out and cause it to fall off. However, tea tree oil can cause skin irritation, so it should be used cautiously and diluted with a carrier oil if necessary.
  
• Apple Cider Vinegar: Apple cider vinegar is another home remedy that is often used for skin tag removal. The idea is that the acid in the vinegar helps break down the tissue of the skin tag, causing it to fall off over time. Like tea tree oil, apple cider vinegar can cause irritation or a stinging sensation, so it should be used with care.
  
• Garlic: Some people apply crushed garlic to skin tags, believing that its enzymes will break down the tissue. However, this remedy is not scientifically supported and may lead to skin irritation if left on the skin for too long.

• Amoils Skin Tag Remover: Another great option to consider is Amoils Skin Tag Remover, a product made with 100% natural ingredients. It combines active ingredients like Calendula (marigold) and Eastern Arborvitae (Thuja), along with an essential oil blend of Lemon peel, Tea Tree, Lemon Balm, and Eastern Arborvitae. This product has garnered excellent reviews for its effectiveness in gently and naturally removing skin tags, offering a non-invasive solution for those looking to avoid harsh chemicals. It’s a convenient, ready-made option that uses the power of nature to help address skin tags.
  

For those who prefer a more natural approach, trying these remedies first can be a great option before considering harsher, chemical-based products or professional treatments. It’s not always necessary to immediately reach for over-the-counter products, which can sometimes contain strong chemicals that may cause irritation, especially for those with sensitive skin.

At-Home Removal

For those looking for at-home removal methods, there are a couple of options that don’t require over-the-counter products:

Tying Off (Ligation Method)

One common method of at-home skin tag removal is tying off the tag with a piece of dental floss, string, or a rubber band. This technique works by cutting off the blood supply to the skin tag. Without blood flow, the skin tag will eventually wither and fall off.

To use this method, you’ll need to carefully tie the string tightly around the base of the skin tag and keep it in place for several days. While this is a relatively simple and inexpensive approach, it can be difficult to do safely without professional assistance, and improper technique could lead to infection or scarring.

Freezing and Cryotherapy (At-Home Devices)

Home cryotherapy devices are also available for removing skin tags. These devices work similarly to the cryotherapy treatments offered by doctors but are designed for use at home. They typically involve a freezing agent like liquid nitrogen that is applied directly to the skin tag.

These devices may work effectively for smaller skin tags, but they can also be tricky to use. It’s important to carefully follow instructions and be cautious not to freeze the surrounding skin, as this could cause burns or scarring.

Professional Treatments

For more stubborn or larger skin tags, or for individuals who prefer a professional approach, several in-office treatments are available. These methods are usually faster and more effective than at-home options and are typically performed by a dermatologist or medical professional.

Cryotherapy (Performed by a Doctor)

Cryotherapy performed by a doctor uses liquid nitrogen to freeze off skin tags. The doctor applies the nitrogen directly to the skin tag, freezing the tissue and causing it to fall off after a few days. Cryotherapy is a relatively quick procedure and is often used for small to medium-sized skin tags.

While this method is effective, it can cause some discomfort, and there may be a small risk of scarring or discoloration, particularly if the surrounding skin is damaged during treatment. However, when done by a trained professional, cryotherapy is a safe and effective option.

Excision and Cutting (Surgical Removal)

Excision is the process of cutting off the skin tag using a sterile scalpel or surgical scissors. This method is often used for larger or more persistent skin tags. The procedure is typically done under local anesthesia to ensure that the patient does not feel any pain during the removal.

After the skin tag is removed, the wound is usually stitched up, and the recovery time is relatively short. Excision is a highly effective method, but it may leave a scar, especially if the skin tag was large or deep.

Electrocautery (Burning Off Skin Tags)

Electrocautery is a procedure that uses electrical currents to burn off skin tags. This technique works by applying heat to the skin tag, which causes it to shrink, dry out, and fall off. Electrocautery is commonly used for small skin tags and can be performed in a dermatologist’s office with minimal discomfort.

The primary benefit of electrocautery is that it is quick and relatively painless. However, like with excision, there may be some scarring, especially if the procedure is not performed carefully.

Laser Treatment

Laser treatment uses concentrated light beams to vaporize the skin tag. The laser targets the blood vessels within the skin tag, causing it to collapse and fall off. Laser treatment is an effective option for removing skin tags, particularly for those in sensitive areas such as the face or eyelids.

Laser removal is precise and usually results in minimal scarring. It is particularly beneficial for people with dark skin tags, as lasers can be tailored to target specific colors and wavelengths. However, laser treatment can be more expensive than other methods.

Which Treatment is Best?

The best treatment for skin tags largely depends on the size, location, and number of tags, as well as the patient’s preferences. For small, uncomplicated skin tags, at-home remedies or over-the-counter products may be sufficient. However, for larger or more numerous skin tags, professional treatments like cryotherapy, excision, or electrocautery are often more effective.

It’s also important to consider factors like cost, potential scarring, and recovery time when choosing a treatment option. Consulting with a dermatologist or medical professional can help determine the best approach for your particular case.

Post-Treatment Care

Once a skin tag has been removed, whether through a professional procedure or at home, it’s important to follow proper aftercare to ensure smooth healing and minimize the risk of complications.

Healing After Removal

For most individuals, healing after skin tag removal is straightforward. If the skin tag was removed through excision or electrocautery, the treated area will need to be kept clean and protected to promote healing. You may experience some mild discomfort, redness, or swelling around the site, which should subside within a few days.

For home removal methods, such as tying off the tag or using cryotherapy, the area may take a bit longer to heal. It’s important to avoid picking at or scratching the area to prevent infection or scarring.

Signs of Complications

Though rare, complications can occur after skin tag removal. Signs that you may need to seek medical attention include:

• Infection: If you notice increasing redness, warmth, pus, or pain around the removal site, it could be a sign of infection.
• Excessive bleeding: If bleeding continues or worsens after removal, it’s important to contact a healthcare provider.
• Persistent pain or swelling: Some mild discomfort is normal, but if you experience prolonged or severe pain, it may indicate a problem.

When to See a Doctor

If any of the above complications occur, it’s essential to seek medical advice as soon as possible. Additionally, if you experience abnormal growth or changes in the appearance of your skin after removal, consult with a healthcare provider to rule out any underlying conditions.

Common Myths and Misconceptions About Skin Tags

There are several myths surrounding skin tags that may lead to confusion or unnecessary worry. Let’s address some of the most common misconceptions.

Do Skin Tags Indicate Cancer or Serious Health Issues?

Skin tags are harmless and non-cancerous growths. They do not indicate any underlying health issues or increase the risk of developing skin cancer. However, any new or unusual growth on the skin should be evaluated by a healthcare professional to rule out other conditions, such as moles or warts.

Can Skin Tags Be Contagious?

No, skin tags are not contagious. They are a result of friction, genetic factors, and certain medical conditions, but they cannot be spread through contact with another person.

Are Skin Tags Just a Cosmetic Issue?

While skin tags are typically benign and not medically concerning, they can cause discomfort if they become irritated or rub against clothing. In some cases, individuals may choose to have them removed for cosmetic reasons, but skin tags do not pose a health risk.

Can Skin Tags Fall Off on Their Own?

One common myth is that skin tags will always fall off on their own without any treatment. While it’s true that some small skin tags may dry out and fall off naturally—especially if they become irritated or lose blood supply—this isn’t the norm for most people. Most skin tags remain in place unless removed through natural remedies, over-the-counter solutions, or medical procedures.

Skin Tags in Specific Areas of the Body

While skin tags can appear anywhere on the body, they are more common in certain areas due to friction, skin folds, or specific health conditions. In this section, we will look at some of the common areas where skin tags tend to appear and the particular considerations for each.

Skin Tags on the Neck

The neck is one of the most common areas where skin tags develop. This is primarily due to constant friction from clothing, jewelry, or skin-to-skin contact. People with excess weight, for example, may experience more friction in this area.

Considerations: Skin tags on the neck can sometimes be more noticeable, especially in individuals with darker skin tones. Since they are more exposed, they can become irritated by clothing, necklaces, or frequent touching. Read more about this here.

Skin Tags Under the Arms (Axilla)

The underarms are another common location for skin tags, especially because the area experiences a lot of friction from both skin rubbing against skin and clothing. Sweating can also irritate the skin, which may contribute to the development of skin tags in this region.

Considerations: Skin tags in the underarm area can sometimes be challenging to remove on your own, as they are typically small and in a sensitive area. Shaving can also contribute to irritation or even accidentally nick a skin tag, which may cause discomfort or bleeding. It is important to be cautious when attempting any home treatments to avoid irritation.

Skin Tags on the Eyelids

Eyelid skin tags, though less common, can occur in individuals as they age. The skin on the eyelids is thin and delicate, and friction from blinking or the constant movement of the skin can lead to the formation of skin tags.

Considerations: Skin tags on the eyelids may cause discomfort or even interfere with vision if they grow large enough. These should always be removed by a healthcare professional, as the area around the eyes is sensitive. Excision or laser treatment performed by a dermatologist is often recommended for eyelid skin tags.

Skin Tags in the Groin and Genital Area

The groin area, particularly where skin folds and rubs together, is another area where skin tags can form. These are more commonly seen in individuals who are overweight, as excess weight increases friction in these areas.

Considerations: Skin tags in the groin area are generally not a cause for concern but can be uncomfortable if they become irritated. Removing them in this sensitive area should always be done under the guidance of a healthcare provider to avoid complications.

Skin Tags Under the Breasts

Women, particularly those who are overweight, may develop skin tags under the breasts, where skin rubs against skin. These tags may also be more likely to develop during pregnancy, when hormonal changes cause increased skin friction.

Considerations: Skin tags under the breasts can become irritated by bras or tight clothing. It’s important to wear well-fitting clothing and to keep the area dry to prevent further irritation. If skin tags become bothersome, they should be removed with care to avoid infection or injury.

Skin Tags vs. Other Skin Growths

Skin tags are often confused with other types of skin growths, such as warts, moles, or seborrheic keratosis. While they are generally benign, it’s essential to understand the differences between skin tags and these other growths to ensure proper treatment.

Skin Tags vs. Warts

Warts are caused by a viral infection (human papillomavirus, or HPV) and are typically rough and raised, whereas skin tags are smooth, soft, and hang off the skin. Warts tend to appear on the hands, feet, and other parts of the body, while skin tags typically form in areas of friction.

Key Differences:

• Warts: Caused by HPV, rough texture, contagious.
• Skin Tags: Non-contagious, smooth texture, non-cancerous.

Skin Tags vs. Moles

Moles are typically dark, raised spots on the skin that can vary in size and shape. While most moles are harmless, some may develop into melanoma, a form of skin cancer. Skin tags, on the other hand, are usually flesh-colored or slightly darker and do not change in appearance over time. Moles should be checked regularly for changes in shape, size, or color, as these could indicate a higher risk of skin cancer.

Key Differences:

• Moles: Dark in color, irregular shape, potential for cancerous growth.
• Skin Tags: Flesh-colored, smooth, benign growths.

Skin Tags vs. Seborrheic Keratosis

Seborrheic keratosis is a benign, wart-like growth that is often darker than skin tags and appears more textured. While seborrheic keratosis is non-cancerous, it can be mistaken for a mole or skin cancer if it changes rapidly.

Key Differences:

• Seborrheic Keratosis: Darker, rough, appears more like a wart or mole.
• Skin Tags: Flesh-colored, smooth, smaller in size.

Are Skin Tags dangerous? When to See a Doctor

If you are uncertain about whether a skin growth is a skin tag or another type of growth, it’s always a good idea to consult with a dermatologist. This is particularly important if the growth is changing in size, shape, or color, as these could be signs of something more serious. Your dermatologist can properly identify the growth and provide appropriate treatment options. Click the heading to learn more about the dangers of skin tags – Are Skin Tags Dangerous.
