A skin tag is a soft, benign outgrowth of skin on a stalk — collagen and tiny blood vessels wrapped in normal surface skin. They grow where skin rubs against skin or collar: neck, underarms, eyelids, under the bust, groin. Harmless by nature, annoying by location, and never improved by home string-and-scissors surgery.

Repeated mechanical stress in predisposed skin drives a small outgrowth of collagen and vessels that the epidermis obligingly covers, producing the classic soft papule on a stalk [1,2]. Age, genetics, pregnancy hormones and weight gain all raise the count. They are not warts and carry no virus in the typical case — another skin-tag myth that survives on resemblance alone.
One tag means nothing. Numerous tags are worth a sentence of internal medicine: the literature repeatedly associates multiple acrochordons with insulin resistance, obesity and metabolic syndrome — the tags themselves are harmless, but they can be a visible marker of a metabolic pattern worth checking with simple blood work [1]. It is a conversation, not an alarm. Separately, anything atypical — a “tag” that is firm, pigmented, growing or bleeding without friction — steps outside the pattern and earns proper diagnosis before removal, the same rule as for seborrhoeic keratoses.
In-clinic removal is quick and definitive: fine-scissor snip excision for pedunculated tags, electrocautery or laser for small or numerous ones — each takes seconds per lesion, with local anaesthetic where useful [2]. Eyelid tags call for the most careful technique and are still routine clinic work. Removed tags do not regrow; new ones can appear in the same friction zones over the years, so patients with a strong tendency often book a periodic tidy-up. Where the neighbouring concern is the underarm itself — sweat, odour, shadowing — the underarm programme covers that territory.
The string method — tying off a tag at home invites infection, incomplete removal and unnecessary pain for something a clinic ends in seconds. Nail scissors — bleeding and infection risk without sterile technique. Over-the-counter freeze products near the eyes — genuinely dangerous. And tag-removal creams and patches — a fibrovascular stalk does not dissolve; irritated skin around an intact tag is the usual result.
“A skin tag is harmless — but many skin tags are occasionally a message about metabolism, and that message is worth one blood test, not ten home remedies.”
— Dr Sin Yong
One or two mean essentially nothing. Numerous tags associate statistically with insulin resistance and metabolic syndrome — worth mentioning to a doctor, not worth losing sleep over.
No — removal neither spreads nor multiplies them. New tags reflect your skin's tendency, not the removal.
Occasionally a tag twists on its stalk, loses blood supply and drops off. Most persist indefinitely until removed.
Momentary — snip excision and cautery are seconds per tag, with anaesthetic for larger ones. Most patients rate it far below expectation.
Eyelid skin is thin, mobile and constantly folding — friction again. Eyelid tags need careful technique but are routinely removed in clinic.
No. Typical tags are fibrovascular outgrowths, not viral lesions — they are not contagious and do not spread by touch.
