BACKGROUND: Hypertrophic scars from severe burns cause physical and psychological stress. Proper treatment, including CO₂ laser systems, can alleviate these burdens by enabling skin remodeling and collagen production. This study assessed the efficacy of a new laser device with 2 wavelengths (10 600 nm/1540 nm) and 2 scanning units on hypertrophic burn scar management.

CASE REPORT: A 34-year-old African woman sought treatment for a large hypertrophic burn scar on her right foot. The scar, formed at age 9, was complicated by infection. She underwent 2 CO₂ sessions (Scar3 scanner), followed by 3 cycles of fractional CO₂ +1540 nm laser (µScan DOT scanner) once a month, combined with topical hyaluronic acid. She also had 2 maintenance sessions with a 595-nm dye laser to prevent scar reactivation. The CO₂ and 1540 nm laser synergy improved laxity through volumetric thermal effects, causing contraction and stimulation. This led to a softer, smaller scar with less consistency. The patient experienced significant improvement in quality of life due to alleviation of pain and restored footwear comfort.

CONCLUSIONS: The hypertrophic burn scar was effectively treated using 10 600 nm and 1540 nm wavelengths, along with dye laser treatment for recurrence prevention.
