  "what": "Thermage FLX is a non-invasive monopolar radiofrequency device made by Solta Medical that passes current at 6.78 MHz from a single-use tip, heating the deep dermis and fibrous septae so collagen contracts and remodels gradually. At Dr Sin Yong's practice on Orchard Road, Singapore, he performs it personally for mild to moderate laxity of the face and eyelids in a face that has kept its volume. It does not add volume, reduce fat, remove excess skin or reposition deeper tissue, and for the neck he uses the VF Lift – Vertical Facelift and Time Freeze Laser LCLR® instead.",
  "key_facts": [
    "Mechanism: capacitively coupled monopolar radiofrequency at 6.78 MHz, bulk heating of the skin envelope rather than discrete points, with cryogen cooling of the surface",
    "Tips: single-use face, eye and body tips; the eye tip treats lid skin with protective shields placed under the lids after anaesthetic eye drops",
    "Suits: mild to moderate laxity in skin that still recoils when pinched, and crepey lid skin with the brow in a reasonable position",
    "Skin colour: radiofrequency heats through electrical resistance rather than melanin absorption, so skin colour is less of a factor than with many lasers",
    "Does not: raise a descended brow, remove a lower-lid fat bag, lift a lid edge that sits low from a weak muscle, or remove marked excess skin",
    "Technique: several lower-energy passes guided by the patient's report of heat, with cooling and vibration on each pulse",
    "Risks: redness, warmth, swelling and tenderness are common; rarely a superficial burn or blister, or a contour dip from injury to the fat beneath the skin"
