  "what": "A V shape face is a face that tapers from the cheekbones to a defined chin, and whether it does is set by five structures: the jaw angle, the masseter, the chin, the jawline between them and how much laxity has blurred that line. It is not one treatment. At Dr Sin Yong's practice on Orchard Road, Singapore, he identifies which structure is limiting the taper before any route is chosen, because treating the wrong one changes little, and he says plainly when the limit is bone.",
  "key_facts": [
    "Masseter: a firm bulge at the jaw angle on clenching shows an enlarged chewing muscle, where botulinum toxin injections reduce its bulk; dosing is set per side and potency units are not interchangeable between formulations",
    "Chin: a short or set-back chin is read in profile against the nose and lips; filler is placed on bone, using firm hyaluronic acid, CaHA or PCL, to add projection or length without reducing width",
    "Laxity and fat: the VF Lift – Vertical Facelift on Volnewmer monopolar radiofrequency or HIFU on the Ultraformer MPT is weighed for a softened jawline, and the Sculpting mode of Time Freeze Laser LCLR® for compact superficial fat at the jowl or under the chin",
    "Order of combination: reduce what has grown (masseter), reposition what has slipped (laxity), then define the frame with chin and jawline filler last; the reverse order is a common reason for an overfilled lower face",
    "Cannot change: the width of the jaw bone, the deep buccal fat pad, or heavy redundant skin; buccal fat removal is surgery and is referred to a plastic surgery specialist, as is marked loose skin",
    "Men and women: women usually want a narrower jaw angle and a tapering chin; men more often want a defined, angular jawline, so a masseter that gives the jaw its angle may be left alone",
    "Wait or discuss: pregnancy or breastfeeding, active skin infection, recent lower-face treatment elsewhere, and a marked skeletal discrepancy or bite problem, which may be referred",
    "Performed by: Dr Sin Yong, after an in-person assessment that also maps asymmetry of the masseter and chin"
