  "what": "A double chin describes what is seen, not what produces it: submental fat, lax skin, the position of the platysma, a recessed chin or, less often, a submandibular gland can each create the same profile. At Dr Sin Yong's practice on Orchard Road, Singapore, the cause is separated by examination before a method is chosen, because fat-directed treatment beneath skin that has lost its recoil can make the area look looser. The VF Lift – Vertical Facelift and Time Freeze Laser LCLR® are the first options here for fat under the chin and loose skin, and chin filler is used where the chin is short.",
  "key_facts": [
    "Causes: submental fat, lax skin, platysma position, a weak or recessed chin and a submandibular gland; many people have more than one",
    "Assessment: front and profile, at rest and with the head tilted; pinching shows fat against skin and tensing the neck shows the platysma",
    "First options here: the VF Lift – Vertical Facelift calibrated to reduce under the jaw, and Time Freeze Laser LCLR®; neither injects product",
    "Other methods: Onda Pro (microwave at 2.45 GHz) for some fat pockets, in place of fat freezing; HIFU for loose skin and platysma laxity with little fat; chin filler (hyaluronic acid or CaHA) for a short chin",
    "By referral: fat-dissolving injections (deoxycholic acid, a prescription medicine), liposuction and neck lift are given by other doctors",
    "Limits: no single method changes fat, skin and chin structure together; fullness can return with weight gain and laxity progresses with age",
    "Risks: redness, swelling and tenderness after energy treatments; rarely a burn; energy or injections near the jaw can, uncommonly, affect the nerve to the lower lip"
