  "what": "Acne scar treatment is chosen scar by scar, because ice-pick, boxcar, rolling and tethered scars form differently. At Dr Sin Yong's practice on Orchard Road, Singapore, tethered scars are released with subcision, ice-pick tracts are treated at their base with TCA CROSS, and resurfacing with fractional CO2 or RF microneedling comes last, once the scar is free to remodel. Active acne is settled first, and the aim is a shallower, less visible scar rather than complete removal.",
  "key_facts": [
    "Scar types: ice-pick (narrow, deep tracts), boxcar (defined walls, shallow or deep), rolling (wave-like dips from fibrous bands) and tethered (flattens when the skin is stretched)",
    "Matching: ice-pick to TCA CROSS then the S3 Resurfacing Lift; shallow boxcar to FSX Laser; deep boxcar to the S3 Resurfacing Lift (multi-depth fractional CO2 on the DEKA SmartXide Tetra); rolling to subcision then RF microneedling or S3; tethered to subcision, sometimes with CaHA in the released space",
    "Sequence: release first, support second, resurfacing last; each stage is reviewed against photographs before the next is timed",
    "Skin type: on Fitzpatrick III to V skin, passes are lighter and staged because of the risk of post-inflammatory pigmentation",
    "Not scars: flat red marks (post-inflammatory erythema) and brown marks (post-inflammatory hyperpigmentation) are assessed separately and take vascular or pigment care",
    "Referral: punch excision, punch elevation, grafting and formal scar revision are performed by a plastic surgery or dermatology specialist; Dr Sin Yong does not perform them",
    "Performed by: Dr Sin Yong, who holds the Certified Key Opinion Leader Trainer certificate for the DEKA SmartXide Tetra Pro and does every consultation and treatment himself"
