Skin tags are removed safely and permanently through three quick in-office procedures: snipping, freezing with liquid nitrogen, or burning with an electric current. Most visits take under 15 minutes, and the tags don’t grow back once removed. While the internet is full of DIY methods, the FDA has stated there are no over-the-counter drugs legally sold for skin tag removal, and the agency has issued warnings about products marketed for this purpose causing injuries and scarring.
What Skin Tags Are and Why They Form
A skin tag is a small, soft, benign growth that hangs from a thin stalk of skin. They typically appear in areas where skin rubs against skin or clothing: the neck, armpits, under the breasts, groin folds, and eyelids. They’re flesh-colored or slightly darker, usually just a few millimeters across, and painless unless something snags on them.
Friction is the primary trigger. This is why skin tags are especially common in people who carry extra weight, where more skin-on-skin contact occurs throughout the day. Hormonal shifts also play a role. High levels of estrogen and progesterone during pregnancy can accelerate their growth, and growth factors that stimulate cell turnover have been linked to their development. Some dermatologists view them simply as a byproduct of skin aging, with multiple factors stacking up over time.
There’s also a metabolic connection worth knowing about. Research published in the Journal of Investigative Dermatology found that the number of skin tags a person has correlates with markers of metabolic syndrome, including waist circumference, blood sugar levels, and triglyceride levels. If you’re developing clusters of new skin tags, it may be worth having your blood sugar checked, not just your skin examined.
Professional Removal Methods
Dermatologists use three standard techniques, and the choice depends mostly on the size and location of the tag.
- Snip removal. The dermatologist numbs the area (or doesn’t, for very small tags) and cuts the tag off at its base with sterile scissors or a scalpel. This is the most common method for larger tags and gives an immediate result.
- Cryotherapy. Liquid nitrogen is applied directly to the tag, freezing the tissue. The tag blisters, shrivels, and falls off within a week or two. This works well for small to medium tags.
- Electrosurgery. A small electric current burns through the stalk of the tag. This method is precise and can also cauterize the area to minimize bleeding, making it useful for tags in sensitive spots.
All three methods are quick, low-pain procedures done in a single office visit. Local numbing is available for any of them, though many small tags are removed with little more than a brief sting.
What Recovery Looks Like
Aftercare is simple. Clean the area with soap and water twice a day. Avoid hydrogen peroxide or rubbing alcohol, both of which slow healing. A thin layer of petroleum jelly under a nonstick bandage keeps the wound moist and protected. The spot left behind is typically small enough that scarring is minimal, especially when removal is done by a trained provider.
Most people return to normal activity immediately. The treated area may be slightly tender or pink for a few days. Cryotherapy sites can blister before healing, which is expected. Keep the area clean and covered, and avoid picking at any scabbing that forms.
Why DIY Methods Are a Bad Idea
Search online and you’ll find advice about tying off skin tags with dental floss, dabbing on tea tree oil or apple cider vinegar, using at-home freezing kits, or applying baking soda and castor oil pastes. None of these have scientific evidence supporting their effectiveness. As one Banner Health dermatologist put it plainly, there is no proof these over-the-counter products work, and you risk skin irritation, bleeding, and scarring.
The FDA’s position is even more direct. The agency has confirmed there are no OTC drugs that can be legally sold for mole or skin tag removal, and it has issued consumer warnings about injuries from products marketed for these uses. The concern isn’t just that they don’t work. It’s that people may mistakenly treat a growth that isn’t actually a skin tag. Seborrheic keratoses, for example, look similar but are flat, waxy, and sit on the skin’s surface rather than dangling from a stalk. More importantly, certain skin cancers can mimic benign growths. Self-diagnosing and treating at home could delay a diagnosis that matters.
Cost and Insurance Coverage
Most insurance plans don’t cover skin tag removal because it’s classified as cosmetic. If a tag is irritated, bleeding, or causing pain, your provider may be able to document it as medically necessary, which improves the chance of coverage. Without insurance, the cost varies by provider and the number of tags being removed, but a straightforward office visit for removal is generally comparable to other minor dermatology procedures. Ask your provider’s office for a cost estimate before scheduling.
How to Prevent New Skin Tags
You can’t guarantee skin tags won’t return, but two strategies reduce the odds. First, minimize chronic friction. Avoid tight necklaces, rough shirt collars, or jewelry that rubs the same spot repeatedly. Moisture-wicking clothing and anti-chafing products help in areas like the inner thighs and underarms. Second, if you’re carrying excess weight, losing even a moderate amount reduces skin-fold friction and may improve the metabolic factors tied to tag formation. Keeping blood sugar levels stable matters too, given the strong correlation between insulin resistance and skin tag development.
When a Skin Tag Might Not Be a Skin Tag
The hallmark of a true skin tag is its stalk. It hangs off the skin like a tiny balloon on a string, is soft to the touch, and doesn’t change color or grow rapidly. Growths that are flat, firm, irregularly shaped, multicolored, or rapidly expanding deserve professional evaluation. Seborrheic keratoses are the most common lookalike. They’re brown or black, have a waxy or “stuck-on” appearance, and sit flush against the skin rather than dangling. They’re also benign, but distinguishing them from something more serious requires a trained eye. Any growth you’re unsure about is worth showing to a dermatologist before you attempt to remove it yourself.
