1470 nm Diode laser for enhancement of the Lower Face: a prospective evaluation with patients’ and physicians’ reported outcomes

Background Lower facial aging and loss of jawline definition are common concerns among many patients. While surgical procedures offer definitive correction, many individuals seek minimally invasive options with shorter recovery times. The 1470-nm diode laser aims to address this by promoting skin tightening and restoration of the mandibular contour. Aims Evaluate the efficacy and safety of this laser in the treatment of mild to moderate lower facial laxity using validated patient-reported outcomes and independent clinician assessments. Methods We identified patients with mild to moderate lower facial laxity who underwent a single treatment; those with severe laxity, previous procedures in the treatment area, or used combined modalities were excluded. Assessments included the FACE-Q® Satisfaction with Facial Appearance scale and standardized 2D/3D photography at baseline, 3 months, and 6 months. Three independent plastic surgeons, blinded to timing, evaluated pre- and post-treatment images using the Global Aesthetic Improvement Scale (GAIS). Results Twenty-six patients were included. FACE-Q® scores improved from a baseline mean of 47 to 54 at 3 months and 62 at 6 months. GAIS evaluations showed aesthetic improvement in 61–74% of patients, with no cases of worsening. Two patients developed temporary marginal mandibular neuropraxia, resolving by 6–10 weeks. Conclusion the 1470 nm diode laser demonstrated measurable improvement in lower facial laxity with minimal downtime and acceptable safety. It represents a promising minimally invasive alternative for selected patients, although longer-term and controlled studies are needed to validate durability and refine indications.
