Skin Tags: The Complete Guide to What They Are, Why You Get Them, and How to Remove Them

You noticed one in the mirror, or you felt it when your necklace caught. A small, soft flap of skin, hanging off your neck, your armpit, your eyelid, or under your bra line. It does not hurt. It is the same color as the rest of your skin, or maybe a shade darker. And then you started spotting more of them.

Most likely, these are skin tags. They are one of the most common benign growths in adults, almost half of people have at least one by middle age, and they are almost always nothing to worry about. This guide walks through what they are, why you get them, when they actually need a doctor, and what your options are if you want them gone.

What is a skin tag?

A skin tag is a small, soft growth of skin that hangs from the body by a thin stalk. The medical name is acrochordon. They are made of loose collagen fibers and tiny blood vessels wrapped in normal skin, and they grow outward rather than into the skin.

They are not warts, they are not moles, and they are not contagious. You did not catch them from anyone. They formed because of how your skin responded to friction, age, hormones, or a combination of all three.

What a skin tag looks like

A typical skin tag is anywhere from a pinhead to the size of a pea, though some grow larger. They are soft, hang loose, and move easily when you touch them. Most are flesh-colored, but some are slightly darker than the surrounding skin, especially in darker skin tones.

They show up most often in places where skin rubs against skin or against clothing. The neck. The armpits. The eyelids. Under the breasts. The groin and inner thighs. You can also get them on your back or chest, but those high-friction zones are where they cluster.

According to the American Academy of Dermatology, skin tags are extremely common after age 30, and the number a person has tends to climb with each decade.

What causes skin tags?

The honest answer is that no single cause has been pinned down. What is well documented is the combination of factors that put a person more likely to get them.

Friction is the dominant trigger

The single most consistent pattern in skin tags is that they grow where skin rubs. Necks under collars, armpits under sleeves, eyelids where you blink, under bra straps, between thighs. The repeated low-grade rubbing is thought to stress the skin and trigger the small overgrowth that becomes a tag.

This is also why people who carry extra weight tend to develop more of them. More skin folds means more friction zones, not because of the weight itself, but because of the mechanical contact. For more on the location pattern, see skin tags on the neck.

Age and genetics

Skin tags become much more common after 30 and continue to multiply through the 40s, 50s, and beyond. They also run in families. If your parent had a scattering of tags on their neck or under their arms, you are more likely to develop them in the same places. This is the strongest and most consistent pattern in the research: age is the clearest factor, family history is the second.

Pregnancy, perimenopause, and hormones

Many women first notice skin tags during pregnancy or in perimenopause, which has led researchers to look closely at hormones as a contributing factor. Estrogen and progesterone shifts seem to play a role in how the skin behaves, and the pattern of new tags appearing in those windows is consistent enough that it is widely accepted. If you are pregnant or in your 40s and seeing new tags, you are in the most common group of all. It is a normal change. For the pregnancy-specific deep dive, see skin tags and pregnancy.

The metabolic-health association

This part deserves calm, accurate phrasing. Research has consistently found an association between having many skin tags and conditions like insulin resistance, type 2 diabetes, and metabolic syndrome. According to NIH MedlinePlus, people with diabetes are more likely to develop skin tags.

The word that matters here is association. Skin tags are not a diagnosis of anything, and most people with skin tags have nothing wrong metabolically. But if you have suddenly developed a lot of new skin tags, especially alongside other changes (weight gain, increased thirst, dark patches in the skin folds called acanthosis nigricans), it is worth a conversation with your primary care doctor. Not panic. A conversation. For the broader why-now read, see why am I suddenly getting skin tags.

Are skin tags dangerous?

No. A skin tag is a benign growth. It does not spread, it does not turn into something harmful on its own, and having them does not mean something is wrong with your skin. For the large majority of people, a skin tag is a cosmetic and comfort issue, nothing more.

That said, "almost always harmless" is not "always," and the next two sections are the part worth reading carefully.

Skin tags and skin cancer: the honest answer

A true skin tag does not become skin cancer. They are different things. The reason this question comes up is that some skin cancers can look like a small growth, and most people cannot reliably distinguish their own skin lesions by eye.

The rule is simple. A skin tag stays the same: same size, same color, same shape, year after year. Anything that behaves differently is not following the skin tag pattern. Sudden growth, color change, bleeding without trauma, pain, or a tag that looks different from your others should be looked at by a dermatologist. That is not fear. That is the one check worth doing.

When a skin tag needs a doctor, not a guess

See a dermatologist if a tag bleeds on its own without being bumped or caught on clothing, grows or changes shape, changes color, has an irregular border, becomes painful, or simply does not look like your other tags. Also see one for any tag on the eyelid, genitals, or anal area. Those locations are too sensitive for at-home removal and warrant a professional touch. And see one if you are simply not sure what it is. Identifying skin growths is what dermatologists do. A quick check is always reasonable. For what to do if one starts bleeding, see why is my skin tag bleeding.

Skin tag, or something else?

Plenty of small growths look similar at a glance. Here is how a skin tag compares to the things it gets confused with.

Skin tag vs wart

A wart is firm, rough, and often has a cauliflower-like surface. Warts are caused by HPV (human papillomavirus) and are contagious, both to other people and to other parts of your own body. A skin tag is soft, smooth, hangs loose, and is not contagious. If the growth is hard and rough, treat it as a wart, not a tag. The treatment is different.

Skin tag vs mole

A mole is usually flat or slightly raised, pigmented (brown, black, or tan), and made of pigment cells. A skin tag is the color of your skin (or close to it), soft, and on a stalk. Pigmented growths belong with a dermatologist, especially if they have any of the ABCDE warning signs (asymmetry, border irregularity, color variation, diameter over 6mm, evolution). Do not treat a pigmented spot at home with any device. For the full identification breakdown, see skin tag vs wart vs mole.

Skin tag vs seborrheic keratosis

Seborrheic keratoses are waxy, "stuck on" looking growths that are usually brown or tan and have a slightly rough surface. They look almost like they could be peeled off (but they cannot). A skin tag is soft and dangles. If the growth looks like a brown wax drop pressed onto the skin, that is a keratosis, not a tag.

Skin tag vs neurofibroma

Less common, but worth mentioning. A neurofibroma is a soft, flesh-colored growth that can look very similar to a skin tag. Most are benign and isolated. Multiple neurofibromas, especially with other skin findings like café-au-lait spots, can be a sign of a genetic condition called neurofibromatosis and warrant a doctor visit. A single soft growth that looks like a tag is almost always a tag. A cluster of soft growths that have a different texture and feel deeper than a tag is worth a check.

Where skin tags fit: the benign skin growth family

A skin tag is one member of a larger group called benign cutaneous growths. The family includes skin tags (acrochordons), moles (nevi), seborrheic keratoses, cherry angiomas, sebaceous hyperplasia, and milia, among others.

Knowing the category matters for one practical reason. When you read about treatment, the methods overlap (cautery, cryotherapy, excision) but the right method depends on what kind of growth you actually have. A method that works beautifully for a skin tag may be wrong for a mole, and vice versa. This is also why identification comes first and treatment second.

How do dermatologists treat skin tags?

A dermatologist has several quick, effective options for skin tag removal. The most common are snip excision (small sterile scissors remove the tag at the base), electrocautery (heat closes off the blood supply and removes the tag), cryotherapy (liquid nitrogen freezes the tag and it falls off over the next week or two), and ligation (a small thread or band is tied at the base to cut off blood supply, the tag dries out and falls off).

All of these work. The trade-offs are cost (clinics typically charge per tag, which adds up if you have a dozen on your neck), booking time, and the trip. For one or two tags on a sensitive area, the clinic is often worth it. For a scattered handful on the neck or armpits, at-home options are a reasonable path.

Can you remove skin tags at home?

Yes, for tags you are confident in and in locations that are not on the eyelid, genitals, or anal area, at-home removal is possible. The two methods with real evidence are physical removal (a plasma pen device, which cauterizes the tag the same way a clinic does, scaled to handheld use) and ligation (a small band that cuts off blood supply at the base of the tag).

This is where an at-home plasma pen, like the OcuraLife 6-in-1 Plasma Pen, fits in. The device delivers plasma energy to the base of the tag. That energy treats the tissue directly, a small scab forms, and as your skin renews the scab lifts away on its own.

A note on what does not work. Tea tree oil, apple cider vinegar, and other folk remedies appear all over the internet for skin tag removal. There is no real clinical evidence that these reliably remove tags, and apple cider vinegar in particular can burn surrounding skin if applied repeatedly. Topical creams do not penetrate the skin tag in any meaningful way, because the issue is structural and not surface-level. We say this not to be precious, but because choosing the wrong method at home can mean weeks of irritation for no actual result.

What to expect from at-home plasma pen treatment

A single tag takes about five minutes from start to finish, including aftercare prep. A small scab forms over the treated spot almost immediately, and over roughly the next three to seven days the scab does its job and falls off on its own. By about two to three weeks, the skin in that area has usually renewed and looks clear.

Aftercare matters and is simple: keep the area clean and dry, do not pick the scab, and protect the spot from the sun while it heals. For the full method walkthrough, see how to get rid of skin tags at home.

When should you see a doctor instead?

Skip the at-home route and book a dermatologist if any of the following is true. The tag bleeds without being bumped. It is growing or changing in any way. It has changed color. It has an uneven border. It hurts. It does not look like your other tags. It is on an eyelid, genital area, or anal area. Or you simply are not sure it is a skin tag.

There is no downside to having a professional confirm what something is. The at-home option is for the tags you already know.

The bottom line

Skin tags are common, benign, and a normal part of how skin changes with age and friction. They are not dangerous, they are not cancer, and they are not a sign you did anything wrong. The habit worth keeping is the same as with any skin growth: notice change. A stable tag is the ordinary kind. A tag that bleeds, grows, changes color, or appears in a sensitive location deserves a professional look.

If you are confident about your tags and want them gone, the OcuraLife 6-in-1 Plasma Pen was built for at-home removal of skin tags and related benign growths. The step-by-step companion guide walks through doing it correctly.
