Skin tags are small, soft flaps of skin that hang from the body by a thin stalk, and they’re extremely common. Nearly half of the general population develops them at some point, with rates climbing to 59% by age 70. They’re harmless, painless, and don’t require treatment. But if a skin tag catches on clothing, jewelry, or just bothers you cosmetically, removal is straightforward.
Professional Removal Options
A dermatologist or primary care doctor can remove a skin tag in minutes during a routine office visit. The three most common methods are cryotherapy, cauterization, and simple excision, and all work well for typical skin tags.
Cryotherapy uses liquid nitrogen to freeze the skin tag. The extreme cold destroys the tissue, causing a small scab to form that falls off on its own within a few days to a couple of weeks. It’s quick, requires no anesthetic for small tags, and leaves minimal scarring. Cauterization takes the opposite approach: a small heated device burns the base of the tag, sealing tiny blood vessels as it goes so there’s almost no bleeding. Excision is the most straightforward option. The doctor numbs the area and snips the tag off with medical scissors or a scalpel. This is often preferred for larger skin tags or ones your doctor wants to send for examination under a microscope.
Most people walk out of the office with nothing more than a small bandage. The procedure rarely takes more than a few minutes per tag, and discomfort is minimal.
What It Costs
Insurance, including Medicare, typically covers skin tag removal only when a doctor considers it medically necessary. That usually means the tag is bleeding, infected, painful, growing, changing color, or physically interfering with movement (common spots include the armpits and groin). Purely cosmetic removal is generally out of pocket. The total cost varies by location and facility, but if you do have coverage through Medicare, you’ll pay the annual deductible plus roughly 20% of the approved amount after that.
Over-the-Counter Removal Kits
Drugstores sell skin tag removal kits that work in a few different ways. Some use a freezing mechanism similar to cryotherapy, applying a cold substance to the tag at home. Others use small rubber bands or ligation devices to cut off blood flow to the base of the tag until it shrivels and drops off. You’ll also find topical solutions marketed for skin tags, though many of these contain homeopathic ingredients with no strong evidence behind them.
OTC freezing kits are the closest thing to a professional treatment you can do at home, but they don’t reach the same temperatures as medical-grade liquid nitrogen. They work best on very small, clearly identifiable skin tags on accessible parts of the body. Follow the instructions carefully, since applying the cold too broadly can damage surrounding skin.
Home Methods and Their Risks
One of the most widely shared DIY approaches is tying off a skin tag at its base with dental floss or thread, then waiting for it to fall off as the blood supply is cut. This can work for smaller tags, and most people who try it won’t have a serious problem. But there are real downsides. As the tissue dies, the tag can develop an unpleasant smell from decay. More importantly, tying off skin in a non-sterile setting creates a risk of infection, especially if the tag doesn’t detach cleanly or the area stays moist.
Cutting off a skin tag yourself with scissors or nail clippers is riskier still. Skin tags have a blood supply running through their stalk, and even a small one can bleed more than you’d expect. Without proper instruments and a sterile environment, you’re also opening the door to infection.
Apple cider vinegar and tea tree oil are popular suggestions online. Neither has clinical research supporting its effectiveness for skin tags, and both frequently cause skin irritation. Applying concentrated acetic acid (the active component in vinegar) to skin can cause chemical burns, particularly on sensitive areas like the neck, eyelids, or underarms where skin tags tend to appear.
Caring for Your Skin After Removal
Whether a doctor removed your skin tag or you handled it at home, the wound care basics are the same. Clean the area gently with soap and water twice a day. Avoid hydrogen peroxide and rubbing alcohol, both of which slow healing. A thin layer of petroleum jelly covered with a non-stick bandage keeps the site moist and protected while new skin forms. The spot may be slightly pink or tender for a few days, but most small removal sites heal quickly without any lasting mark.
When a Skin Tag Needs a Closer Look
The vast majority of skin tags are completely benign. But any skin growth that changes color, shifts in shape, bleeds spontaneously, or looks different from a typical soft, flesh-colored tag deserves a professional evaluation. A dermatologist can examine the growth and, if needed, send it for biopsy to rule out anything more serious. This is one of the strongest reasons to have a doctor handle removal rather than doing it yourself: a tag that looked harmless can be examined under a microscope after it’s removed.
Why Skin Tags Form in the First Place
Skin tags develop in areas where skin rubs against skin or clothing: the neck, armpits, under the breasts, groin folds, and eyelids. Friction is the primary trigger, which is why they’re more common in people who carry extra weight or have naturally loose skin.
There’s also a metabolic connection. Research published in the Journal of Investigative Dermatology found that people with skin tags are three to four times more likely to have metabolic syndrome, a cluster of conditions including high blood sugar, excess abdominal fat, and elevated triglycerides. The number of skin tags a person develops correlates with blood glucose levels and waist circumference. This doesn’t mean skin tags are dangerous on their own, but if you’re developing many of them, it may be worth having your blood sugar and metabolic markers checked.
Hormonal changes during pregnancy can also trigger skin tags, as can aging. Genetics play a role too. If your parents had them, you’re more likely to develop them.
