A skin tag is a small, soft, harmless growth that hangs off the skin. It often appears in adults, especially in places where skin rubs together, such as the neck, armpits, groin, or under the breasts. Skin tag usually causes no symptoms, but it can catch on clothing or jewelry and become irritated, and what people describe as early symptoms of skin tag is often just noticing a tiny flap of skin. These growths can last for years and are not linked to death or cancer in the usual case. It may help to know that doctors have studied this condition for decades, and treatment is only needed if a skin tag bothers you, with common options including simple removal in a clinic.
How many people live with Skin tag?
There is no single direct worldwide count for skin tags, but StatPearls summarizes that about 50%-60% of adults have at least one, with rates varying by age and by how carefully studies look for them (StatPearls, 2023). Using that adult range, a rough estimate is about 3-4 billion people worldwide (United Nations, 2024; StatPearls, 2023) and about 130-160 million people in the United States (U.S. Census Bureau, 2024; StatPearls, 2023).
Overview
Skin tagSymptoms
Skin tags are usually soft, small growths on the skin that often cause no symptoms. People with a skin tag may notice rubbing, irritation, or tenderness, especially where clothing or skin folds create friction.
Outlook and prognosis
Skin tag is harmless and usually stays stable over time. Many living with skin tags need no treatment unless one catches on clothing, bleeds, or becomes bothersome. Removal is usually quick, and new skin tags can still appear later.
Causes and risk factors
Skin tags can develop when skin rubs against skin, especially in body folds. Risk rises with age, weight gain, pregnancy, insulin resistance or diabetes, and family tendency; friction and hormonal changes may make skin tags more likely.
Genetic influences
Genetics do not seem to play a major direct role in skin tag formation for most people. Skin tags are more often linked to factors like friction, weight, age, and insulin resistance, though inherited tendencies may slightly affect who gets them.
Diagnosis
Skin tag is usually diagnosed during a routine skin exam, based on its typical soft, small, flesh-colored appearance. Tests are rarely needed. If it looks unusual, a clinician may remove it and send it for lab testing.
Treatment and drugs
Skin tag treatment is often only needed if a tag rubs, bleeds, or bothers you. A clinician can remove a skin tag in the office by freezing it, snipping it off, or using heat.
Symptoms
Most skin tags are painless and easy to miss unless they rub on clothing or jewelry. People with skin tags often notice a small, soft bump that hangs off the skin, especially in places where skin rubs together. For many people with skin tags, the main problem is irritation, snagging, or how it looks rather than true pain. Early symptoms of skin tag can be subtle, and some are found by chance while shaving or getting dressed.
Many skin tags cause no pain, itching, or other symptoms. People often notice them simply because they can see or feel a small extra piece of skin.
A skin tag usually feels soft, flexible, and smooth or slightly wrinkled. It may be flesh-colored or a little darker than the surrounding skin.
Many skin tags stick out from the skin on a thin stalk. This can make them easier to catch on collars, bras, necklaces, or razors.
Rubbing from clothing, shaving, or skin-on-skin contact can make a skin tag feel sore, itchy, or tender. This is more common on the neck, underarms, groin, or under the breasts.
How people usually first notice Skin tag?
People usually first notice a skin tag as a tiny, soft, flesh-colored bump that seems to appear out of nowhere, often in places where skin rubs against skin or clothing, such as the neck, armpits, eyelids, groin, or under the breasts. At first, it may look like a small flap of loose skin or a smooth bump on a thin stalk, and many people become aware of it only when it catches on jewelry, shaving, or clothing, or when they see it in the mirror. Skin tags are usually painless and harmless, but if one becomes irritated, twists, bleeds, or changes quickly, it is a good idea to have a clinician take a look.
Types of Skin tag
Skin tag can look a little different from one person to the next, even though these growths are usually harmless and often cause no symptoms at all. In practice, the main types of skin tags are usually described by how they are attached to the skin and how large or narrow they are, rather than by separate diseases. Symptoms don’t always look the same for everyone. For many living with skin tag, the biggest difference is whether the tag simply sits there unnoticed or gets rubbed by clothing, jewelry, or shaving.
Pedunculated tags
This is the classic skin tag, hanging off the skin on a small stalk. It often feels soft and movable, and many people notice it on the neck, underarms, groin, or under the breasts. It may only become bothersome if it catches on clothing or jewelry.
Filiform tags
These are thinner, more thread-like skin tags that can look narrow and elongated. They may stand out more on the eyelids, neck, or face because of their shape, even when they are small. Some may find them more annoying during washing, shaving, or applying makeup.
Broad-based tags
Some skin tags are attached with a wider base and can look more like a soft raised bump than a dangling flap. They may be less obvious as one of the variants of skin tag at first, especially in skin folds where friction is common. When rubbed often, they can become tender, red, or irritated more easily.
Can I slow down the onset of symptoms?
There is no proven way to meaningfully delay or prevent skin tags. Research suggests that lowering skin rubbing, keeping weight in a healthy range, and managing diabetes or other blood sugar problems may reduce the risk of getting new ones in some people, but that is not the same as preventing them and the evidence is limited. The good news is that skin tags are usually harmless, and if they start bothering you or change in appearance, a doctor can check them and remove them safely.
What genetics can tell you about symptoms
Genetics can play a small role in whether skin tags tend to run in a family, so some people may be more likely to develop them, have more of them, or notice them earlier in adult life. But there is no well-established genetic test that can predict exactly which symptoms you will have, how bothersome a skin tag will feel, or how severe it will be. For most people with skin tags, day-to-day factors such as skin rubbing, body weight, age, pregnancy, and blood sugar problems seem to matter more than genetics.
Causes and risk factors
Skin tags often form where skin rubs on skin or clothing, such as the neck, armpits, groin, or under the breasts. Age, pregnancy, and health problems linked to insulin resistance, such as higher body weight or type 2 diabetes, can raise the chance of getting skin tags. Skin tags also tend to run in families, so inherited traits may make some people more likely to develop them. Think of risk factors as pieces of a puzzle, not the whole picture. For many, what causes skin tags is a mix of friction, body chemistry, family history, and weight-related lifestyle factors.
What are the most common causes or risk factors?
Skin tags often happen where skin rubs against skin or clothing, so they are more common in areas like the neck, armpits, groin, or under the breasts. They are more likely in people who are overweight, during pregnancy, and as people get older, and they are also seen more often in people with diabetes or high blood sugar. Family history matters too, so if close relatives get skin tags, you may be more likely to develop them as well.
Environmental and biological risk factors
Skin tags are more likely to show up in places where the skin gets rubbed or where body hormones and growth signals are more active. Doctors often group risks into internal (biological) and external (environmental). The main risk factors for skin tags are repeated friction, getting older, insulin-related conditions, and hormonal changes such as pregnancy.
Repeated rubbing between nearby skin, tight clothing, or jewelry can make skin tags more likely. This helps explain why they often appear on the neck, underarms, groin, eyelids, or under the breasts.
Skin tags become more common with age, especially from midlife onward. Years of small skin changes and ongoing friction may both play a part.
Skin tags are more common in people with insulin resistance, prediabetes, type 2 diabetes, or metabolic syndrome. Higher insulin and related growth signals may encourage extra skin growth.
Hormone shifts during pregnancy can make skin tags appear or grow more easily. They are especially common in areas where skin rubs together.
Genetic risk factors
If skin tags seem to run in your family, there may be an inherited tendency behind them. It’s usually a combination of influences rather than one clear cause, and most people with a skin tag do not have a single identifiable gene change. Rarely, having many skin tags or getting them early in life can point to one of the genetic causes of skin tags seen in inherited syndromes.
Family history: Many people with skin tags have close relatives who also get them, which suggests a hereditary tendency. This does not mean you will definitely develop skin tags, but your chance may be higher if they are common in your family.
Multiple genes: For most people, ordinary skin tags are not linked to one single gene change. Instead, several small inherited differences may work together and make the skin more likely to form these soft growths.
Rare syndromes: In a small number of cases, numerous skin tags or skin tags that appear early in life can be part of a rare inherited condition. When this happens along with other unusual skin findings or a strong family history of related health problems, a genetics evaluation may be helpful.
Lifestyle risk factors
Skin tags are often linked to metabolic and mechanical factors rather than one single cause. When people ask about lifestyle risk factors for skin tag formation, the clearest patterns involve weight, insulin resistance, skin friction, and habits that promote these changes over time. Diet and physical activity matter mainly because they influence body weight, blood sugar regulation, and skin folds where tags commonly appear. These factors do not guarantee skin tags, but they can make them more likely.
Carrying excess body weight increases skin folds and repeated rubbing in areas like the neck, armpits, and groin. It is also associated with insulin resistance, which is commonly seen in people who develop multiple skin tags.
A sedentary lifestyle can promote weight gain and poorer blood sugar control over time. This may increase the chance of developing skin tags, especially when inactivity contributes to abdominal weight gain and metabolic strain.
Diets high in refined carbohydrates, sugary drinks, and highly processed foods can worsen insulin resistance and make weight gain more likely. In people prone to skin tags, these changes may support the hormonal and metabolic conditions in which tags appear more often.
Constant rubbing from tight clothing, jewelry, or repeated skin-on-skin contact can irritate areas where skin tags tend to form. This is especially relevant in warm, moist body folds where friction happens day after day.
Risk prevention
Skin tags are common, harmless growths, and there is no guaranteed way to prevent every skin tag. They tend to form more often where skin rubs on skin or clothing, so prevention mostly focuses on lowering friction and managing health factors linked with them. Prevention is about lowering risk, not eliminating it completely.
Skin tags often develop in areas like the neck, underarms, groin, or under the breasts where skin rubs repeatedly. Looser clothing, well-fitting bras, and reducing chafing during exercise may help lower that irritation.
Extra skin folds can increase rubbing, which may raise the chance of skin tags. For many living with skin tag problems, gradual weight loss can help reduce friction and also improve related metabolic risks.
Skin tags are more common in people with insulin resistance, prediabetes, or diabetes. Keeping blood sugar in a healthy range through food choices, movement, and medical care may help reduce the risk of new skin tags.
Regular physical activity supports weight control and helps the body use insulin more effectively. Alongside medical care, everyday habits also matter.
Can you prevent Skin tag?
You cannot fully prevent skin tags, because they often happen for reasons you cannot control, such as age, body shape, and family tendency. Still, you may be able to lower the chance of getting some of them by reducing ongoing skin rubbing, especially in areas like the neck, armpits, groin, or under the breasts, and by working toward a weight that is healthy for you if extra skin folds are causing friction. If you have diabetes, keeping it well managed may also help, but it does not guarantee that skin tags will not form.
Transmission
Skin tag is not infectious, so it cannot be passed from one person to another through touching, kissing, sharing towels, or sexual contact. If someone close to you has a skin tag, being around them will not make you develop one.
Some people ask about the genetic transmission of Skin tag, and while skin tags can be more common in some families, they are not usually inherited in a simple parent-to-child pattern. For many living with skin tags, these growths are more closely linked to skin rubbing, body changes such as pregnancy, and common health factors rather than anything contagious.
When to test your genes
For skin tags, genetic testing is usually not needed. Most are common, harmless growths linked more to friction, weight, age, and insulin resistance than to a single inherited cause. If you develop many suddenly or alongside other unusual findings, a clinician may look for underlying health issues, but not typically through gene testing.
Diagnosis
Skin tags are usually diagnosed during a routine skin exam because they have a very typical look and feel. Many living with skin tags first notice a soft, tiny growth on the neck, underarms, groin, or under the breasts when getting dressed or shaving. Doctors usually begin by looking closely at the spot and asking when it appeared, whether it has changed, and if it catches on clothing. In most cases, the diagnosis of skin tag is straightforward and does not require extensive testing.
A doctor usually diagnoses a skin tag by examining its shape, color, size, and the small stalk that often attaches it to the skin. Skin tags are typically soft, flesh-colored or slightly darker, and easy to move gently between the fingers.
Your provider may ask when the growth first appeared, whether it has grown, and if it bleeds, hurts, or gets irritated. This helps confirm it behaves like a skin tag rather than another common skin growth.
Part of how skin tag is diagnosed is making sure it is not a wart, mole, or another harmless or less common skin lesion. If the spot is unusually dark, firm, fast-growing, or has an irregular surface, your doctor may look closer or refer you to a skin specialist.
In some cases, a dermatologist may examine the growth with a magnified lighted tool to see surface details more clearly. This is more likely if the tag is in a sensitive area, has an unusual appearance, or the diagnosis is not fully clear at first.
How is Skin tag diagnosed?
Skin tags are usually diagnosed during a simple skin exam, because a doctor can often tell by their soft, small, flesh-colored growth and the places they tend to appear, such as the neck, underarms, eyelids, or groin. Most people do not need any special tests. If a growth looks unusual, changes quickly, bleeds, or could be something else, the doctor may remove a small piece or the whole spot to check it more closely.
Stages of Skin tag
Skin tag does not have defined progression stages. That is because a skin tag is usually a small, benign growth that may stay much the same over time or slowly enlarge, rather than moving through clear step-by-step phases. Doctors usually start with a conversation about when it appeared, whether it rubs on clothing or jewelry, and whether there have been changes in color, bleeding, or pain. In most cases, diagnosis is made by looking at the skin during an exam, and if there is any doubt about how to tell if a skin tag is harmless, a doctor may remove it or test it to rule out another skin condition.
Outlook and prognosis
The outlook for people with skin tags is excellent, as these growths are benign and do not become skin cancer. They often remain stable or slowly enlarge over time, and some may become irritated by friction from clothing, jewelry, or shaving. Removal, when desired for comfort or cosmetic reasons, is usually simple and effective, although new skin tags can develop later, especially in people with obesity, insulin resistance, or repeated skin friction. Skin tags do not affect life expectancy, and mortality is not associated with the condition itself. Medical review is worthwhile if a growth changes quickly, bleeds, becomes painful, or looks unlike a typical skin tag, because another skin condition may be present.
Long-term effects
For most people, skin tags are a long-term nuisance rather than a serious health problem. The long-term picture is often very stable: many skin tags stay the same for years, while some slowly get larger or more numerous over time. Many living with skin tags notice issues mainly when they rub on clothing, jewelry, or nearby skin, or when their appearance becomes bothersome.
Skin tags are benign growths and do not usually turn into skin cancer. Many stay unchanged for a long time and cause no medical problems beyond mild annoyance.
Some skin tags remain tiny, while others slowly enlarge over months or years. Early symptoms of skin tags are often just a soft bump that catches on clothing or feels noticeable when washing or shaving.
Skin tags in the neck, armpits, groin, or under the breasts can get rubbed and twisted repeatedly. This may lead to soreness, redness, minor bleeding, or tenderness, especially if they snag on fabric or jewelry.
People with skin tags can develop new ones over time, especially in skin folds where skin rubs together. A removed skin tag usually does not grow back in the exact same spot, but new skin tags can form nearby or elsewhere.
How is it to live with Skin tag?
Living with skin tags is usually more of a nuisance than a health threat, because these small, soft growths are benign and often cause no symptoms at all. For many people, daily life is only affected if a tag rubs on clothing, jewelry, or skin folds, which can lead to irritation, snagging, or occasional tenderness, and some may also feel self-conscious if the tag is in a visible area. Skin tags do not spread from person to person, so they do not pose a risk to family, friends, or close contacts, although they can still have a quiet emotional effect if they make you less comfortable with your appearance.
Treatment and drugs
Skin tag treatment is usually only needed if a skin tag gets irritated, bleeds, catches on clothing or jewelry, or bothers you cosmetically. Many living with skin tag find that removal is a quick office procedure, and doctors may use freezing, snipping with sterile tools, or burning the tissue with heat, depending on the size and location. Treatment often looks different for each person, but most skin tags should not be cut off at home because this can lead to bleeding, infection, or removing the wrong kind of skin growth. If you notice fast growth, pain, repeated bleeding, or a change in color, a doctor should check it before removal to make sure it is really a skin tag and not something else.
Can you cure Skin tag?
There is no true cure that stops skin tags from forming, but an existing skin tag can usually be removed safely. A doctor may remove it by cutting it off, freezing it, or burning it off, which can help if it rubs on clothing, bleeds, or bothers you. Even after removal, some people may get new skin tags over time.
Non-drug treatment
Skin tags are harmless growths, so treatment is often about comfort, irritation, or appearance rather than medical need. Many living with skin tag notice them where skin rubs, such as the neck, armpits, groin, or under the breasts, and that rubbing can make them catch on clothing or jewelry. For many, treatment begins not at the pharmacy, but with deciding whether a tag needs to be removed at all. If you are looking into skin tag treatment options, it is safest to use methods done or advised by a medical professional.
Many skin tags do not need treatment if they are small, painless, and not getting in the way. Keeping an eye on size, color, bleeding, or repeated irritation can help you know when to ask a clinician to check it.
Skin tags often get more bothersome in spots where skin or clothing rubs all day. Loose clothing, reducing chafing, and avoiding necklaces or straps that catch on them can make daily life more comfortable.
A clinician can remove a skin tag by cutting it off with sterile tools during a quick office visit. This is often used for tags with a narrow stalk, and the area may be sore briefly afterward.
Cryotherapy removes some skin tags by freezing the tissue so it shrivels and falls away. You may need more than one strategy, since not every tag responds the same way and some need a repeat treatment.
Your genes may have an impact on how drugs work for you
For skin tags, genes usually do not have much effect on treatment because these growths are most often removed with simple office procedures rather than treated with medicine. If a numbing shot or cream is used, people can respond a little differently, but this is usually not something doctors match to your genes in everyday care. In other words, genetic testing is not a routine part of skin tag treatment, and it is rarely needed to decide what works best.
Pharmacological treatments
Most people with a skin tag do not need medicine, because skin tags are usually treated by simple office removal or left alone if they are not bothersome. There is no standard pill or prescription cream that reliably makes a skin tag go away. When medication is used, it is usually to numb the area before removal or to treat irritation or infection afterward, not to remove the skin tag itself.
There is no approved medicine that reliably removes a skin tag on its own. If you are searching for the best medication for skin tags, the answer is often that no drug is needed and a quick in-office procedure works better.
Lidocaine is a local anesthetic that may be injected to numb the skin before a larger or sensitive skin tag is snipped or burned off. Sometimes medicines are taken short-term, and this is a good example because it is used only during the procedure.
Topical anesthetic creams such as lidocaine-prilocaine may be used before removal, especially for people who want to avoid an injection. They do not treat the skin tag itself, but they can make the procedure more comfortable.
Antibiotic creams or ointments are not usually needed for a simple skin tag. If the area becomes infected after being irritated or removed, a doctor may recommend treatment such as mupirocin, depending on how it looks.
Genetic influences
Skin tags often seem more common in some families than others. It’s natural to ask whether family history plays a role. Genetics may affect how your skin grows and how easily it forms small overgrowths, which can make some people more likely to develop skin tags, but genes are only part of the picture. Age, rubbing in skin folds, higher body weight, pregnancy, and conditions linked with insulin resistance can also raise the chance of getting skin tags. So if you are wondering whether skin tags are hereditary, the short answer is that they can run in families, but having relatives with skin tags does not mean you will definitely get them. There is no routine genetic test for ordinary skin tags, because no single gene is known to explain most cases.
Is Skin tag genetic?
Genetics do not seem to play a major direct role in skin tag formation for most people. Skin tags are more often linked to factors like friction, weight, age, and insulin resistance, though inherited tendencies may slightly affect who gets them.
Having a genetic risk is not necessarily a diagnosis
Changes in genes are a normal part of human biology and are common throughout the general population. Most of these changes do not have a direct effect on health and simply reflect natural human diversity. For many genes, carrying a change associated with a condition suggests a possible link rather than a certain diagnosis, especially when more than one gene and environmental factors are involved. In some situations, however, a single well-understood change in a specific gene can be enough to confirm a diagnosis.
Pharmacogenetics—how genetics influence drug effects
For most people with skin tags, treatment is chosen based on where the tag is, how large it is, and whether it catches on clothing or jewelry, not on a genetic test. Skin tag treatment usually involves removal by freezing, snipping, or burning, and there is no well-established pharmacogenetic test that helps doctors decide which option will work best. Many living with skin tags notice that they seem to run in families, so inherited traits may play a part in who gets them. Not every difference in response is genetic, but healing after skin tag removal can also vary because of skin type, diabetes, circulation, and the body area being treated. If a numbing medicine or aftercare product is used, doctors usually choose it based on your health history, allergies, and other medicines rather than your genes. So when people ask how genetics influence skin tag treatment, the answer is that genes may affect the tendency to develop skin tags more than the way skin tag treatment itself is selected.
Interactions with other conditions
Skin tags often show up alongside metabolic health problems such as overweight, insulin resistance, type 2 diabetes, and sometimes abnormal cholesterol levels. Many people live with more than one health issue at a time. For some living with skin tag growths, especially when many appear or they keep coming back, this can be a clue to ask whether blood sugar or other features of metabolic syndrome should be checked. Skin tags are also seen more often during pregnancy, when hormone changes and higher insulin levels can make them more likely, and they may be more common in people with polycystic ovary syndrome. In rare cases, a sudden increase in numerous skin tags can happen with other internal illnesses, but most skin tags are harmless and not a sign of cancer. If you notice early symptoms of skin tag clusters or a rapid change in how many you have, it is worth discussing with your doctor in the context of your overall health.
How genes can cause diseases
Humans have more than 20,000 genes, each carrying out one or a few specific functions in the body. One gene instructs the body to digest lactose from milk, another tells the body how to build strong bones and another prevents the body's cells from beginning to multiply uncontrollably and developing into cancer. As all of these genes combined are the building instructions for our body, a defect in one of these genes can have severe health consequences.
Through decades of genetic research, we know the genetic code of any healthy/functional human gene. We have also identified that in certain positions on a gene, some individuals may have a different genetic letter from the one you have. We call these hotspots "Genetic Variations" or "Variants" in short. In many cases, studies have been able to show that having the genetic letter "G" in the position makes you healthy, but having the letter "A" in the same position disrupts the gene function and causes a disease. Genopedia allows you to view these variants in genes and summarizes all that we know from scientific research, which genetic letters (Genotype) have good or bad consequences on your health or on your traits.
What other conditions can cause similar symptoms to Skin tag?
Skin tags can be mistaken for warts, moles, or small harmless raised growths that become more common with age. Less often, a skin cancer or another abnormal growth can look similar, especially if the spot is firm, painful, bleeds, crusts, changes color, or grows quickly.
History
People have likely noticed skin tag growths for as long as they have looked closely at the body. These small, soft pieces of skin tend to show up in places where skin rubs against skin or clothing, so they were often seen as an ordinary part of getting older rather than a condition worth formally studying. Someone might have found one under an arm while getting dressed, or on the neck after fastening a collar, and simply lived with it.
As medical science evolved, doctors began describing these growths more carefully and separating them from other lumps, warts, and moles. Older medical writing often grouped many harmless skin changes together, because doctors had less detail from microscopes and less agreement about naming. Over time, skin tag became the everyday term many people recognized, while medical descriptions focused on its harmless nature and typical appearance.
In the 19th and 20th centuries, improvements in skin examination and laboratory methods made it easier to show that skin tags are benign, meaning they are not cancer. This mattered because many living with skin tags mainly wanted reassurance: if a bump catches on jewelry, bleeds after shaving, or keeps rubbing under a bra strap or waistband, the worry can feel bigger than the growth itself. Researchers also noticed that skin tags were more common in some groups, including older adults and people with certain metabolic health issues, which helped place them in a broader medical context.
More recently, doctors and researchers have paid closer attention to when skin tags may be a simple cosmetic nuisance and when they might be a clue to other health patterns. That does not mean a skin tag is dangerous on its own. It does mean the history of skin tag has shifted from casual observation to a more complete understanding, including when removal may help comfort, when a new growth should be checked, and how skin changes can sometimes fit into a person’s overall health picture.
