Background: Volume restoration is an essential part of facial rejuvenation.
Objective: To assess long-term full-facial volume restoration using HAEL Volume Lidocaine hyaluronic acid filler.
Methods: An 18-month open study in 60 subjects with at least Grade 2 on the 4-point volume loss scale (VLS) for full face and at least 2 indications affected among chin, temporal areas, jawline, cheeks, cheekbones, and nasolabial folds (NLF). Performance was assessed by VLS, Lemperle rating scale (LRS), investigator Global Aesthetic Improvement Scale (GAIS), and 3-dimensional (3D) imaging.
Results: Most subjects (71.6%) had 3 or 4 indications injected, most commonly cheekbones (96.7%) and NLF (93.3%). At 18 months, at least a 1-grade improvement in VLS was observed for full face (68.3% of subjects), chin (77.8%), temporal areas (73.7%), cheeks (66.6%), cheekbones (58.6%), jawline (43.1%), and NLF (71.4%; LRS). For all indications, more than 60% of the volume gained at 3 weeks was sustained at 18 months based on 3D digital imaging. At 18 months, 95.0% of subjects had improved full-face GAIS and all subjects were satisfied with their aesthetic outcome. One subject (1.6%) had treatment-related adverse events.
Conclusion: Full-facial volume restoration was well sustained over 18 months with high patient satisfaction and good tolerability.
