  "what": "A skin tag (acrochordon) is a benign stalk of collagen and vessels under normal skin, found where skin rubs: the neck, underarms, eyelids, groin and under the bust. At Dr Sin Yong's practice on Orchard Road, Singapore, each lesion is first confirmed as a typical tag, because a raised mole or a wart can mimic one; it is then removed by snip excision, electrosurgery or CO2 laser, chosen by size, base and site, under local anaesthesia. New tags at new sites over the years are common, because the friction and the tendency remain.",
  "key_facts": [
    "Diagnosis first: a lesion that is firm, pigmented, growing or bleeding is diagnosed first, under the dermatoscope where indicated, and kept for histology if removed",
    "Methods: snip excision for fine tags on a narrow stalk and neck clusters; electrosurgery or radiofrequency for small tags and those with a vessel in the stalk; CO2 laser for broader bases",
    "Eyelids: tags on the lid and lash line are removed with a protective shield where needed, the finest instrument and the lowest effective setting",
    "Neck clusters: numerous fine tags are removed in a sequence across the cluster, with the number agreed at assessment",
    "Associations: weight gain, pregnancy and insulin resistance are associated with more numerous tags, so many new tags prompt a conversation about general health",
    "Home removal: creams, thread-tying and home freezing kits are not advised; they half-treat the stalk, risk infection and dark marks, and remove an unexamined lesion",
    "Performed by: Dr Sin Yong personally, after assessment"
