Skin tags: what they are, and why new ones keep appearing
Published 19 September 2026 · Reviewed by Dr Sin Yong
Skin tags are among the most common things I remove — small, soft, stalked growths at the neck, eyelids, underarms and body folds. They are harmless, which is precisely why the internet is full of terrible advice about removing them at home. This guide covers what they are, why you keep growing them, and why the clinic version of removal takes minutes while the home version so often ends in infection, pigmentation, or a misdiagnosed lesion.
Tags cluster where skin rubs skin — neck, folds, underarms — and each is checked before removal.
Key facts
Acrochordon
The medical name for a skin tag — a benign outgrowth of loose dermal collagen and vessels covered by normal skin
Friction sites
Neck, axillae, eyelids, groin and under-breast folds — where skin rubs against skin, collars or jewellery
Prevalence
Roughly half of adults develop at least one tag; frequency rises through middle age
Associations
Tags are more numerous with weight gain, insulin resistance and pregnancy — a skin sign worth knowing, not a disease
Removal methods
Snip excision, radiofrequency or laser ablation, cryotherapy — all minutes-long under local anaesthesia
Stalk (peduncle)
The narrow base carrying the tag's blood supply — why traumatic removal bleeds more than expected
Not contagious
Tags are not viral warts — they cannot spread to other people or other sites
What a skin tag actually is
An acrochordon is a small pouch of loose collagen and blood vessels that the skin extrudes at sites of chronic friction — a structural response, not an infection, not a growth to fear. Half of adults carry at least one. They concentrate exactly where skin rubs against skin or clothing: the sides of the neck, the underarms, the eyelids, under the breasts, the groin creases. Once you know friction drives them, their distribution on your own body suddenly makes sense.
Why you, and why they keep coming
Tag tendency is partly inherited, and partly metabolic. They multiply with weight gain, during pregnancy, and in insulin-resistant states — the skin is, in effect, reporting on its hormonal environment. This has two practical consequences. First, removing today's tags does not remove the tendency; new tags at new sites are common over the years, and that is not a failed treatment. Second, a sudden flourishing of many new tags is worth mentioning to a doctor, since it occasionally accompanies metabolic changes that deserve a blood test rather than a skin treatment.
“Removing today's skin tags does not remove the tendency. New tags are not a failed treatment — they are the same skin doing the same thing.”

Why home removal goes wrong
The internet offers thread-tying, drugstore freezing kits, and worse. The failure modes are predictable: half-treated tags that necrose slowly and get infected; pigmented marks that outlast the tag by years, particularly in Asian skin; bleeding from a stalk that carried a bigger vessel than expected; and — the one that matters — misdiagnosis. Not everything on a stalk is a tag. Warts, seborrhoeic keratoses, naevi and occasionally worse can mimic one, and strangling an unexamined lesion with thread destroys the very tissue that would have answered the question.
How clinic removal actually works
After a look — brief, but real — each tag is removed under local anaesthesia by the method its size and site favour. Fine tags are snipped flush at the base or ablated with radiofrequency in seconds; broader-based tags are removed with the base treated so it seals cleanly. Eyelid tags need the most finesse and the least energy. A session commonly clears dozens of tags across the neck and folds in well under an hour, and healing is a small crust per site for about a week.
Aftercare and the pigmentation question
Aftercare is simple: keep the dots clean and moisturised, let crusts detach on their own, and protect healing sites from sun. In Singapore's climate and in darker skin types, post-inflammatory pigmentation is the main cosmetic risk of any skin procedure — one more reason gentle, controlled removal beats aggressive home methods. Marks that do form fade over weeks to months, and respond to the same pigment protocols used elsewhere on this site.
Skin Tags — Frequently Asked Questions
No — acrochordons are benign. The caveat is diagnostic: other lesions can mimic a tag, so anything unusually firm, pigmented, rapidly growing or bleeding should be examined rather than assumed.
You can; you should not. Home removal risks infection, bleeding, lasting pigmentation and — most importantly — removing an unexamined lesion that was not actually a tag. Clinic removal takes seconds per tag under local anaesthetic.
With local anaesthesia, no — you feel the brief sting of the injection or the cold of a numbing approach, then pressure at most. Multiple tags are routinely cleared in one comfortable sitting.
A properly removed tag rarely regrows at the same spot. New tags at new friction sites are common over the years because the underlying tendency remains — genetics, friction and metabolic factors do not leave with the tag.
Weight change, pregnancy and insulin resistance all accelerate tag formation. A sudden crop of new tags is usually just that — but it is a reasonable prompt for a general check, since the skin sometimes reports metabolic shifts early.
No. Tags are not viral and cannot spread between people or across your own skin. Viral warts — which are contagious — are a different lesion, and telling the two apart is part of the assessment.
Yes — eyelid tags are removed with fine instruments and minimal energy, respecting the thin skin. This is the one site where precision matters most and home attempts are least forgivable.
Each site forms a small crust that separates within about a week, leaving a pink dot that settles over several weeks. Sun protection during healing minimises pigmentation, which is the main cosmetic consideration in our climate.
