Abstract
Background: Individuals with chin retrusion may seek chin and lower jawline aesthetic enhancement.
Objectives: To evaluate VYC-25L (Juvéderm Volux XC; Allergan Aesthetics, an AbbVie company), a lidocaine-containing injectable hyaluronic acid dermal filler, for chin retrusion correction.
Methods: In this prospective, Phase 3, multicenter study (NCT04559984), Chinese adults with moderate-to-severe chin retrusion on the China (Allergan) Chin Retrusion Scale (CACRS) and glabella-subnasale-pogonion (G-Sn-Pog) angle <172.5° were randomized 2:1 to VYC-25L (treatment plus optional touch-up 4 weeks later) or no treatment (control). The primary endpoint was change from baseline (CFB) in G-Sn-Pog angle at Week 24. Secondary endpoints included CACRS response (≥1-point improvement), Global Aesthetic Improvement Scale (GAIS) response (improved/much improved), and FACE-Q Satisfaction with Chin score. Procedural pain was rated (0 = none to 10 = worst imaginable); injection-site responses (ISRs) were recorded daily for ≤28 days.
Results: The mean age of the patient (VYC-25L, n = 97; control, n = 51) was 31.2 years (range, 20-52 years). Mean CFB in G-Sn-Pog angle at Week 24 was 2.97° (VYC-25L) vs 0.09° (control; between-group difference, 3.08° [P < .0001]); improvement was maintained to Week 52. At Week 24, VYC-25L achieved higher responses vs control for CACRS (78.7% vs 18.8%, respectively; rate difference, 60.0%; P < .0001) and GAIS (92.6% vs 4.2%, respectively; rate difference, 88.4%; P < .0001); mean overall FACE-Q Satisfaction with Chin score was 70.4 vs 34.9, respectively. Mean (standard deviation) procedural pain was 2.6 (1.6); most ISRs were mild (41.8%) or moderate (50.0%) in severity.
Conclusions: In Chinese adults, VYC-25L safely and effectively corrected chin retrusion for at least 1 year.
