Current Trends and Future Directions of the Dual 1550‐nm Erbium Glass Fiber and 1927‐nm Thulium Fiber Non‐Ablative Fractional Laser System

OBJECTIVES: To synthesize current evidence and trends supporting the dual 1550-nm erbium glass fiber and 1927-nm thulium fiber non-ablative fractional laser system's mechanism of action and proven efficacy and safety profile in addressing aging skin concerns. METHODS: A review of current evidence and expert consensus was conducted to evaluate the 1550/1927-nm dual laser system. The analysis focused on the 1550 and 1927-nm lasers' specific mechanisms of action and their applications in treating various skin conditions. RESULTS: The 1550-nm laser effectively targets dyschromia, fine lines, and various types of scars, while the 1927-nm laser specifically addresses actinic keratoses, dyschromia, and pigmented lesions. Expert consensus has established standardized protocols while emphasizing personalized treatment approaches on the basis of factors including treatment area and Fitzpatrick skin type. CONCLUSION: The 1550/1927-nm dual laser system's ability to offer customizable settings positions it as a versatile tool in the growing field of esthetic medicine, particularly for addressing the multiple components of skin aging.
