Abstract
Objectives: The present study aimed to evaluate the effectiveness and safety of hyaluronic acid gel for the treatment of volume loss or contour deficiency. Methods: This 6-month, open-label study recruited sixty adults aged 40–65 years with bilateral moderate to severe volume loss or contour deficiency (Facial Volume Loss Scale [FVLS] score: 2–5). Eligible subjects were treated at the baseline visit with an injection of hyaluronic acid gel in one or more of three facial subregions: the zygomatic malar region, the anteromedial cheek and nasolabial folds. Results: A significant improvement from baseline was observed in the FVLS score at each study visit up to 6 months post treatment (p < 0.0125 by Wilcoxon test). A significant improvement was also observed in the Global Aesthetic Improvement Scale (GAIS) at each visit up to 6 months. The study showed that the GAIS score improved in 100% of subjects at month 3, while at the end of the study (month 6) the percentage of improved subjects decreased to 91. Treatment effect was maintained by 100% of subjects up to month 3, while 57% of subjects showed a persistence of effect up to month 6. Conclusions: Volume loss or contour deficiency may be safely and effectively corrected using the new dermal filler.
