Source

A systematic review and network meta-analysis of surgical scar interventions ranked low-level laser therapy and pulsed-dye laser among effective options for minimizing surgical scars.

Evidence grade

moderate

Effect direction

positive

Panel relevance

partially-replicable

Key findings

  • The analysis included 18 RCTs with 482 participants and 671 wounds.
  • Laser and energy-based treatments started within 6 months after surgery were evaluated for scar minimization.
  • Low-level laser therapy ranked favorably, but devices and protocols were clinical and heterogeneous.

Protocol details

WavelengthsNot reported nm
IrradianceNot reported mW/cm2
FluenceNot reported J/cm2
Session timeNot reported minutes
FrequencyVaried across included RCTs
DurationStarted within 6 months after surgery in included studies

Device typeLow-level laser and other energy-based scar devices

Caveats

  • The review covers multiple energy-based modalities, not only red/NIR LED panels.
  • Fresh surgical wounds should follow surgeon wound-care instructions before any light therapy.
