Key Takeaways
- Skin tags are small, soft, harmless growths that develop where skin rubs against skin, clothing, or jewelry.
- Friction, excess weight, age, hormones, and family history are the main reasons skin tags appear and reappear.
- New growths that change color, bleed, itch, or grow quickly should be checked by a medical provider rather than treated at home.
- Professional removal is safer and lower-risk than over-the-counter kits, freezing pens, or tying off with thread.
- PT Family Medicine evaluates and removes skin tags for patients in Jeannette, PA, and you can request an appointment to get a personalized plan.
What Are Skin Tags?
Skin tags (acrochordons) are small, soft pieces of skin that hang from a thin stalk. They usually measure a few millimeters across, although some grow larger over time. Most are flesh-colored or slightly darker than the surrounding skin, and they tend to appear in folds where the skin rubs together.
According to the Cleveland Clinic, about half of adults will develop at least one skin tag during their lifetime, and the likelihood rises with age. They are not contagious, not cancerous, and usually painless, but many patients find them frustrating, especially when new ones keep appearing.
Common locations include:
- Neck and collarbone area
- Underarms
- Eyelids
- Groin and inner thighs
- Under the breasts
- Anywhere clothing rubs
Why Do Skin Tags Appear? Common Causes
Skin tags do not have a single cause. They usually result from a combination of factors that irritate the skin and stimulate cell growth in the upper layers.
Friction and Skin-on-Skin Contact
Repeated rubbing is the most common trigger. That is why skin tags cluster in areas where skin folds touch each other or where collars, bra straps, and waistbands sit against the body.
Weight and Body Composition
Skin tags are more common in people who carry extra weight. More skin folds mean more friction, and metabolic changes linked to higher body weight may also contribute to skin cell turnover.
Age and Hormones
Skin tags become more frequent after age 40. Hormonal shifts during pregnancy, perimenopause, and menopause also raise the risk. Many people first notice them during pregnancy, when hormones and weight changes happen at the same time.
Insulin Resistance and Type 2 Diabetes
Multiple skin tags can be associated with insulin resistance and type 2 diabetes. The American Academy of Dermatology notes that patients who develop several skin tags should consider screening for diabetes if it has not been done recently.
Family History
If a parent or sibling has many skin tags, the chance of developing them goes up. Genetics influences how the skin responds to friction and hormones.
What Causes Skin Tags to Keep Coming Back?
For many patients, the question is not just what causes skin tags but why they keep returning after removal. The short answer: removing a skin tag treats the growth, not the underlying conditions that produced it.
Common reasons skin tags recur include:
- Continued friction in the same area (collar, bra, jewelry, skin folds)
- Weight gain or weight that has stayed in the higher-friction range
- Ongoing hormonal changes, including pregnancy and menopause
- Untreated or undertreated insulin resistance
- Aging skin that responds more easily to irritation
- Genetic tendency toward skin tag development
Recurrence does not mean removal failed. It usually means new tags are forming in nearby areas where the same triggers continue.
When Should Skin Tags Be Medically Evaluated?
Most skin tags are harmless, but some skin growths can mimic skin tags and need professional review. Schedule a visit if a growth:
- Changes color, especially turning dark, red, or black
- Bleeds, oozes, or develops a crust
- Itches or hurts more than briefly
- Grows quickly or appears very different from other skin tags
- Has irregular borders or multiple colors
- Sits on the eyelid and affects vision
- Becomes inflamed or twisted on its stalk
A medical provider can distinguish between a benign skin tag, a mole, a wart, a seborrheic keratosis, and (rarely) a skin cancer that needs further workup. When in doubt, get it checked rather than self-treating.
Skin Tags Treatment: Safe Removal Options vs. At-Home Remedies
Skin tag removal can usually be done in a single, brief office visit. Professional methods are generally faster, cleaner, and less likely to cause infection, scarring, or pigment changes than at-home approaches.
| Removal Method | What It Involves | Pros | Cons |
|---|---|---|---|
| In-office snip excision | Provider numbs the area and snips the tag with sterile scissors | Quick, complete removal, sent for pathology if needed | Mild bleeding, small risk of scar |
| Cryotherapy (freezing) | Liquid nitrogen freezes the tag, which falls off in days | No incision, low pain | May need repeat treatment, can change skin color |
| Electrocautery | Heat seals the stalk and removes the tag | Minimal bleeding | Brief sting, small risk of scar |
| Ligation | Tiny suture cuts off blood supply | No cutting | Tag may take days to fall off |
| Over-the-counter freezing kits | Home version of cryotherapy | Convenient | Often less effective, may damage surrounding skin |
| String or floss at home | Tying off the stalk | Cheap | High infection risk, painful, not recommended |
| Apple cider vinegar, tea tree oil | Topical home remedies | Inexpensive | Limited evidence, may irritate skin or cause burns |
The Mayo Clinic advises against trying to cut, tie, or burn off a skin tag at home because of the risk of bleeding, infection, and misidentifying a skin cancer as a harmless tag.
Prevention Tips to Reduce Future Skin Growths
While not every skin tag can be prevented, several steps may reduce how many appear over time.
Reduce Friction
- Choose loose, breathable clothing in friction-prone areas.
- Use moisture-wicking fabrics for workouts.
- Apply a thin layer of petroleum jelly or anti-chafe balm where skin rubs.
- Make sure bras, collars, and jewelry fit comfortably.
Address Weight and Metabolic Health
- Aim for a steady, sustainable approach to weight management with the help of a primary care provider.
- Discuss screening for insulin resistance or type 2 diabetes, especially if multiple new skin tags have appeared.
- Treat related conditions like high blood pressure or high cholesterol to support overall metabolic health.
Keep Skin Clean and Dry
- Wash and fully dry skin folds daily.
- Use gentle cleansers and avoid harsh scrubs that irritate the skin.
- Apply a light powder or barrier cream in areas that stay moist.
Protect Hormonal and Skin Changes
- During pregnancy, expect that some skin tags may appear and shrink on their own after delivery.
- During perimenopause and menopause, talk with a provider about overall skin and metabolic changes.

Frequently Asked Questions
What causes skin tags?
Skin tags develop from a mix of friction, age, hormones, weight, and genetics. They are common in skin folds where clothing or skin-on-skin contact creates ongoing irritation.
Why do skin tags appear suddenly?
A sudden cluster of new skin tags often coincides with weight gain, pregnancy, or hormonal change. In some cases, several new tags can be an early sign of insulin resistance, which is worth discussing with a primary care provider.
Why do skin tags form in the same spots over and over?
Skin tags tend to return in areas where the same friction or skin-fold environment continues. Removing existing tags does not change the local conditions that produced them, so new growths can appear nearby.
Is skin tag removal near me usually covered by insurance?
Cosmetic skin tag removal is often not covered, but removal of skin tags that are painful, bleeding, infected, or in question for skin cancer may be covered. The office can help check coverage during the appointment.
Are home remedies safe for skin tags?
Home methods like tying off with thread, snipping with scissors, or applying caustic liquids can cause bleeding, scarring, and infection. They also risk treating a growth that is not actually a benign skin tag. Professional removal is safer and more reliable.
When should I see a doctor about a skin tag?
See a provider if a growth bleeds, changes color, grows quickly, hurts, or looks different from other skin tags. Eyelid skin tags and very large or inflamed tags should also be evaluated.
