  "what": "RF microneedling places fine needles into the skin to a set depth and releases radiofrequency heat at their tips inside the dermis, so the surface is largely spared and the skin's repair response can remodel collagen. At Dr Sin Yong's practice on Orchard Road, Singapore, he performs it personally on the Secret DUO for rolling and shallow boxcar acne scars, enlarged pores, uneven texture and early laxity, setting needle depth and energy zone by zone. It does not release tethered scars, clear pigment or lift deeper laxity, and it is not a laser.",
  "key_facts": [
    "Mechanism: radiofrequency energy is released at the needle tips to create controlled thermal zones in the dermis; remodelling is gradual and judged at review",
    "Device: Secret DUO, with needle depth adjustable from 0.5 to 3.5 mm, set deeper over the cheeks and jaw and conservatively around the eyes and over bone",
    "Needles: insulated needles release heat at the tip and spare the surface, and are generally his choice in Fitzpatrick IV to VI skin; non-insulated needles are used for broad, shallow textural work",
    "Concerns: rolling and shallow boxcar acne scars, enlarged pores, uneven texture, early laxity and static fine lines",
    "Sequencing: tethered scars need subcision first and deep ice-pick scars TCA CROSS; it may be combined with the 1540 nm fractional laser on the same platform or a skin booster, with order set at review",
    "Wait or review: active infection, inflamed acne, pregnancy or recent oral isotretinoin mean waiting; a pacemaker, metal or gold-thread implants, keloid tendency or blood thinners need review",
    "Performed by: Dr Sin Yong personally, who was appointed by ilooda Co Ltd to share his Secret DUO microneedling expertise with other doctors"
