Purpose: Soft tissue filler injection is less invasive than surgical approaches for facial aesthetic improvement. This study evaluated the safety and effectiveness of the soft tissue filler VYC-20L (Juvéderm Voluma^® XC) for improvement of volume and aesthetic appearance of the nose in Chinese subjects.

Patients and methods: In a prospective, multicenter, no-treatment-controlled study in China, adult subjects were randomized 3:1 to receive VYC-20L (treatment group) or have optional treatment delayed by 24 weeks (control group). The treatment group received VYC-20L on day 1 plus optional touch-up at week 8 for suboptimal improvement. The primary effectiveness measure was mean change in nose area volume from baseline to week 24 by digital analysis of three-dimensional (3D) images. Multiple secondary effectiveness and safety measures were assessed.

Results: Of 164 subjects randomized, 162 were treated, and 157 comprised the modified intent-to-treat population (mean age, 31 years; 94% female). In the treatment group, mean VYC-20L volume injected was 1.18 mL (initial treatment) and 0.67 mL (touch-up; n = 46 [38.3%]). VYC-20L achieved significantly larger changes in nose area volume than control at week 24 (2.032 vs ‒0.005 cm³, respectively; p < 0.0001) and greater improvements on the Global Aesthetic Improvement Scale (investigator and subject), Nose Satisfaction Scale, and other 3D measures. No treatment-related adverse events occurred. Most injection site responses were mild/moderate, resolving within 14 days. Mean initial/touch-up treatment procedural pain ratings were less than 3 (0‒10 scale; higher = worse pain).

Conclusion: VYC-20L is safe and effective for nose augmentation in Chinese adults.
