What is the reason for skin tags?

They commonly appear on the neck, underarms, eyelids, beneath the breasts, or in the groin, where repeated rubbing can irritate a small fold of skin. A tag may be flesh-coloured or darker and may hang from a narrow stalk. Its appearance can overlap with other growths, so a new, firm, bleeding, painful, rapidly changing, or very dark lesion should not be diagnosed from a photograph alone. A clinician can examine it and decide whether testing is needed.

Do not cut, tie off, burn, or apply unlabelled wart products to a skin tag; these actions can cause bleeding, infection, or a scar. Reduce rubbing with comfortable clothing and keep folds dry. If the growth catches on jewellery, shaves, or clothing, a dermatology clinician can discuss Skin Tag Removal. Depending on its size and position, options may include Cryotherapy (Lesion Removal) or Electrosurgery.

Book an assessment if a lesion changes quickly, bleeds without repeated friction, develops a sore, becomes painful, or differs noticeably from your other skin tags. Seek urgent help for bleeding that does not stop with firm pressure or signs of spreading infection such as increasing warmth, swelling, or fever.

Ask how confident the diagnosis is, whether the lesion should be removed or observed, which method fits its location, and how to care for the area while it heals. Mention any repeated snagging, bleeding, or recent change.
