Background:
Dual-wavelength fractional lasers (1550 nm non-ablative and 1927 nm resurfacing) are well established for rejuvenation and scar remodeling. However, traditional systems often rely on consumable cartridges, fixed scanning geometries, and fiber-based optics, which can limit precision, speed, and environmental sustainability.
Objective:
To retrospectively assess clinical outcomes of facial rejuvenation and acne treatment using a next-generation, solid-state fractional laser system that eliminates disposable components and enables customizable imprint patterns. Unlike prior studies evaluating traditional fractional devices with fixed treatment grids or consumable optics, this investigation examines a compact, maintenance-free platform offering variable density and pattern control, allowing individualized energy distribution across treatment zones.
Methods:
Ten patients underwent eighteen treatment sessions between November 2024 and August 2025 using a novel solid-state 1550/1927 nm laser device. A traditional polygonal pattern was utilized for uniform resurfacing, while the stellate pattern was applied to localized lesions. Clinical outcomes included improvement in pigmentation, texture, and scarring, as well as evaluation of tolerability, downtime, and treatment efficiency.
Results:
Dual-wavelength treatments (69%) achieved the most notable clinical responses, with reported improvement in pigmentation (50%), texture (60%), and scarring (40%). Procedures were well tolerated, frequently performed without anesthesia. The continuous 1927 nm mode allowed smoother, faster coverage of large treatment areas and reduced operator fatigue while maintaining safety and predictable recovery.
Conclusion:
This novel, solid-state, disposable-free 1550/1927 nm dual-wavelength fractional laser demonstrated safe, effective, and efficient performance across multiple indications, including facial rejuvenation and acne-related conditions. Its customizable pattern geometry and continuous energy delivery represent a significant evolution in fractional resurfacing technology, offering improved versatility, treatment uniformity, and sustainability without compromising clinical outcomes.
