Skin Tags: Causes, Appearance, Types, and Removal Options
Home > Health Articles > Skin Tags
What Are Skin Tags?
Skin tags are small, benign growths made up of loose collagen fibers and blood vessels surrounded by skin. They often appear flesh-colored (or slightly darker) and may attach to the skin by a small stalk (also called a peduncle). Skin tags can range from a few millimeters to several centimeters and are most common in areas where skin rubs against skin or clothing, such as the underarms, neck, groin, and eyelids. They’re non-cancerous and generally harmless.
In most cases, skin tags don’t need treatment. But if a tag is irritating, painful, or cosmetically undesirable, skin tag removal may be done by a healthcare professional (or through non-invasive options, depending on the situation).

What Causes Skin Tags?
What causes skin tags? The exact reason a skin tag develops isn’t fully understood. Many people with skin tags have no underlying medical condition. However, skin tags are often linked to friction, especially where skin rubs against skin or clothing.
Obesity
Being overweight or obese may increase the likelihood of developing skin tags. Extra skin folds and friction-prone areas can contribute to irritation, which may encourage these small benign growths to form.
Pregnancy
Hormonal changes during pregnancy may increase skin cell growth, which can contribute to the appearance of new skin tags. Some pregnant women notice existing tags becoming more noticeable or developing in new areas.
Polycystic Ovary Syndrome (PCOS)
Women with PCOS may have a higher risk of skin tags. PCOS is associated with hormonal imbalances and metabolic changes that may play a role in skin overgrowth.
Metabolic Syndrome and Insulin Resistance
Some evidence suggests an association between skin tags and insulin resistance (when the body’s cells don’t respond normally to insulin). Insulin resistance can affect growth-factor activity in the body, which may influence skin cell formation. That said, many people with skin tags have no metabolic condition, and many people with metabolic conditions never develop skin tags.
Do Steroids Cause Skin Tags?
Some discussion exists around topical corticosteroids and skin changes (like thinning or irritation), which could increase friction in certain areas. However, this isn’t considered a common side effect, and more research is needed to clearly define the relationship.
There is usually no medical need to treat or remove skin tags unless they become irritated or their appearance bothers you. If a growth changes noticeably (color, shape, size) or becomes painful or bleeds, it’s best to have it checked by a medical professional.
What Do Skin Tags Look Like?
Skin tags can vary in size, shape, and color. Visually, they may look smooth or slightly rough and can appear alone or in clusters. Many are small and “fleshy,” and some are pedunculated (hanging from a thin stalk).
Skin Tag Peduncle
A peduncle is the thin stalk that can attach a skin tag to the skin. It may be only a few millimeters long, or longer in some cases. Some skin tags are raised on a narrow base, while others have a broader attachment.
Large Skin Tag
Larger skin tags are less common than small ones, but they do occur. Even when they’re bigger, they are typically still benign. People often consider removal when size causes rubbing, snagging, or discomfort.
Skin Tags vs. Moles vs. Warts: How to Tell the Difference
Skin tags can sometimes be mistaken for other skin growths. Here are a few common look-alikes:
- Warts: Warts are small, rough growths caused by an agent. Warts may show up in similar areas, but they’re often firmer and more irregular in texture.
- Moles: Moles are benign growths of pigmented cells that can appear on the skin. Moles are often darker and may be flat or raised.
- Sebaceous cysts: Small cysts under the skin that may feel softer and more mobile than skin tags.
- Syringomas: Benign growths from sweat glands that are usually small and uniform.
- Fibroepithelial polyps: Benign growths that can resemble skin tags and may be larger or more pedunculated.
If you notice a new growth or a growth that’s changing, a dermatologist can confirm what it is and rule out other conditions.
Types of Skin Tags and Common Locations
Skin tags are most often found in areas where skin rubs against skin, including:
- Eyelids
- Neck
- Upper chest
- Underarms
- Armpits
- Breasts
- Backs of the arms
- Abdomen
- Inner thigh
- Groin
This list isn’t exhaustive—skin tags can appear in many places. Below are some common concerns by location.
Eyelid
Skin tags on the eyelids can be irritating when they rub against the eye or surrounding skin. Many people consider removal for comfort or cosmetic reasons, especially when the tag is in a visible area.
Neck
Skin tags on the neck are common, often showing up along the hairline, under the chin, or on the back of the neck. They can snag on clothing or jewelry, and can be confused with other growths—so it’s helpful to have them evaluated if you’re unsure.
Anal
Anal skin tags are not caused by anal intercourse or sexually transmitted diseases. They are commonly associated with issues like anal fissures, hemorrhoids, and healing after rectal problems or surgery.
Anal fissures (small tears) can occur with consistently hard stools, and skin tags may develop as the area heals. Similarly, swelling during recovery after rectal surgery can contribute to tag formation if skin cell growth becomes excessive.
Hemorrhoids (swollen veins) may also be associated with anal skin tags. While the tags themselves are usually not harmful, their presence can be a sign to check for related issues—especially if there is pain, bleeding, or ongoing discomfort.
Body
Body skin tags on the chest may snag on necklaces and clothing, and can sometimes bleed if irritated. Skin tags on the breasts can feel cosmetically bothersome for some people.
The underarms, armpits, and groin area (including upper thighs, inner thighs, and bikini line) can be especially prone to chafing. These areas may become irritated and can be inconvenient for shaving.
Genital
Genital skin tags are benign growths that can appear around the groin, anus, or vulva. They can be smooth or wrinkled, lighter or darker, and may be flat or hang from a stalk. They are not the same as sexually transmitted infections, but any new genital growth should be evaluated to confirm what it is.
Most genital skin tag removal is considered cosmetic and is often not covered by insurance. If tags swell, bleed, or become irritated due to friction, discuss symptoms with your doctor—especially if there are anal or digestive issues alongside an anal growth.
In-office removal options may include snipping/excision, laser removal, cryotherapy, or cautery depending on the tag’s size and location. Some people also explore less invasive approaches when appropriate.
Vaginal
Skin tags in the vaginal area are common and are usually more of a cosmetic concern than a medical problem. Many women want these vaginal skin tags treated if possible. While it is very rare for a skin tag to be cancerous, any changing or unusual growth should be assessed by a clinician.
Groin Skin Tags
Groin skin tags often look like extra skin and may not be a major concern. Penile skin tags can cause more anxiety because people may worry about sexually transmitted infections (even though skin tags are not sexually transmitted). In some cases, tags can occur along a circumcision line due to uneven skin edges.
Skin Tags vs. Molluscum Contagiosum
Molluscum contagiosum is a viral skin condition more common in children than adults. Molluscum bumps can resemble small pimples and often have a central indentation. It spreads through contact and can spread more easily when someone is also dealing with eczema due to scratching.
Although molluscum and skin tags are different, they can be confused at a glance because both may appear pink. Molluscum is typically round, clustered, and does not hang from a stalk. Skin tags, by contrast, may be elongated and pedunculated, forming a flap of skin rather than a dome-shaped bump.
Skin Tags vs. Warts
Skin tags and warts can look similar, but they have different causes and treatment approaches. If you’re unsure which you have, a medical professional can confirm the diagnosis and recommend appropriate care.
Skin Tags
Skin tags are fleshy growths that may appear flat or hang from a stalk. They’re typically the same color as the surrounding skin or slightly darker. You’ll often find them in friction-prone areas like the underarms, eyelids, groin, and neck. They can look alarming, but they are usually harmless.
Warts
Unlike skin tags, warts are contagious. They can spread through skin contact (including sexual contact for genital warts). Warts do not usually dangle like skin tags; they often have a rougher surface and can form clusters.
What Causes Each Condition?
Skin tags are often associated with friction, aging, pregnancy, obesity, and metabolic factors. Warts are caused by a virus (HPV—human papillomavirus), which is why they can spread. Treating warts promptly may help reduce spread to other areas.
When Should a Skin Tag Be Concerning?
Most skin tags are harmless and don’t require treatment. However, it’s a good idea to seek medical guidance if you notice:
- A tag that’s repeatedly irritated or snagged by clothing or jewelry
- Pain, tenderness, or bleeding
- Changes in size, shape, or color
- A growth in a sensitive area (like the face or genitals) that worries you
- Very large tags or many tags appearing quickly
- Concerns due to immune suppression or a personal/family history of skin cancer
If anything about a growth feels “off,” it’s best to have it evaluated by a dermatologist.
Skin Tag Treatment Options
Because skin tags are benign, treatment isn’t medically necessary in most cases. However, removal may be considered if tags are irritating, painful, or cosmetically bothersome.
Common in-office removal methods include:
- Cutting the growth off with sterile scissors or a scalpel
- Freezing the growth off with liquid nitrogen (cryotherapy)
- Laser removal
- Burning the growth off with electrocautery
- Ligation (tying off the base to cut blood supply)
The best method depends on the location, size, number of tags, and clinician preference.
Surgical Excision
During excision, the area is cleaned and the skin tag is removed using sterile scissors or a scalpel. Small tags may be removed quickly, and local anesthesia may be used depending on the tag and location.
Cryotherapy
Cryotherapy uses liquid nitrogen to freeze the growth. Some people choose cryotherapy to reduce friction and chafing, especially in high-rub areas. Your doctor can help you decide whether it’s the right option.
Laser Removal
Laser removal is often chosen for tags in visible areas like the face or neck. It can deliver clean cosmetic results by precisely targeting the growth.
Electrocautery
Electrocautery uses an electrical current to burn off the skin tag. This is typically performed by a trained medical professional, often in a dermatology setting.
Ligation
Ligation involves tying off the base of the skin tag with a small thread or suture to cut off its blood supply. The tag typically dries out and falls off over several days.
Does Insurance Cover Skin Tag Removal?
Medical insurance typically does not cover skin tag removal unless it’s considered medically necessary. In many plans, removal is categorized as cosmetic. However, if a tag is bleeding, repeatedly injured, painful, or interfering with daily activities, coverage may be possible. Check with your insurance provider regarding requirements, deductibles, copays, and any out-of-pocket costs. Some dermatology offices also offer financing options.
Non-Invasive Treatments for Skin Tags
Once you notice skin tags or warts, you can treat them at home with a natural formula designed to be gentle and suitable for sensitive skin.
With consistent use, you may notice the growths gradually declining in size. Doctors can prescribe or perform in-office procedures for more severe growths, but some people explore non-invasive alternatives when appropriate.
How to Get Rid of Skin Tags
- The old-fashioned way: Traditionally, people tied a hair or fine thread around the base of a skin tag to cut off blood supply, causing it to drop off over time. This can be slow, can look unhygienic, and carries an infection risk—especially if the area isn’t kept clean.
- The risky “at home” way: Snipping a growth off with scissors is risky due to infection and bleeding—and because some growths can look like tags but aren’t. Avoid attempting removal this way.
- Cryotherapy: Liquid nitrogen freezing is a common approach. It may cause discomfort or minor scarring, and there is a risk of affecting nearby tissue if not done properly.
- Electrocautery: Often done in a clinic with local anesthesia. A probe burns the tag, and bleeding is controlled to support healing. Healing can take weeks, and scarring is possible.
- Surgical excision: Removal by cutting, performed under local anesthesia for most tags. Discomfort can occur after anesthesia wears off, and scarring is possible.
- Lasers: Used to remove tags, sometimes with good cosmetic outcomes.
- Electrosurgery or electrolysis: A professional uses an electric needle/probe to destroy the growth. It can be fast, but minor scarring may occur.
Common Ingredients Used in Homeopathic Treatments for Skin Tags
Homeopathic approaches for skin tags often rely on plant-derived ingredients and essential oils. Examples commonly mentioned include:
