Improvement of Radial Cheek Lines With Hyaluronic Acid–Based Dermal Filler VYC-17.5L: Results of the BEAM Study

BACKGROUND: Radial cheek lines (RCL) may convey an older, potentially less attractive appearance. OBJECTIVE: To evaluate the effectiveness of hyaluronic acid-based dermal filler VYC-17.5L for correcting RCL. MATERIALS AND METHODS: Fifty-three women (40-65 years) received injections of VYC-17.5L in both cheeks on Day 1 (optional Day 14 touch-up). Effectiveness was evaluated on Day 45 by subject-rated dynamic RCL improvement (Global Aesthetic Improvement Scale [GAIS]; primary end point) and independent, noninjecting investigator-rated GAIS; subject Self-Perception of Age (SPA); subject-assessed satisfaction with and natural look of treatment; and instrument-assessed changes in static and dynamic RCL roughness, amplitude, and texture (secondary end points). Safety assessments included injection site responses (ISRs). RESULTS: On Day 45, 98% of subjects rated RCL as improved or much improved (investigator rated: 95%). Subjects with same or older SPA before treatment (n = 38) perceived themselves as 2.0 and 5.5 average years younger after treatment, respectively. Day 45 mean satisfaction with and natural look of treated areas was 7.9/10 and 7.2/10, respectively. Treatment significantly improved RCL roughness, amplitude, and texture (all p < .001). Most common ISRs were hematoma (35.9%), bruising (30.2%), and irregularities/bumps (22.6%); most ISRs were mild. CONCLUSION: VYC-17.5L effectively corrected dynamic RCL, improved instrument-assessed indicators of skin quality, and resulted in younger age perception.
