Sequential Dual-Wavelength CO2/1540 nm Laser Combined with Pulsed Dye Laser for Hypertrophic and Retractile Scars: A Case Series

Background

Hypertrophic and retractile scars cause functional, aesthetic, and psychosocial burdens and are challenging to treat due to abnormal collagen, inflammation, and vascularity. Traditional therapies show variable results, whereas lasers, fractional CO₂, non-ablative 1540 nm, and pulsed dye laser (PDL), effectively target different aspects of scar pathology.
