Abstract
BACKGROUND: VYC-15L (Juvéderm Volbella XC) is a nonanimal crosslinked hyaluronic acid (HA) gel with lidocaine. OBJECTIVES: To evaluate safety and effectiveness of repeat treatment with VYC-15L administered 1 year after treatment for lip and perioral enhancement. METHODS: In this prospective multicenter study, 124 subjects with minimal, mild, or moderate lip fullness on the validated 5-point Allergan Lip Fullness Scale (LFS) who received initial/touch-up treatment with VYC-15L received repeat treatment with VYC-15L 1 year after initial treatment. Effectiveness endpoints included LFS responder rates (≥1-point improvement from baseline) and scores on the FACE-Q Satisfaction With Lips and Appraisal of Lip Lines scales at 1 month after repeat treatment. Subjects completed safety diaries for 30 days after repeat treatment. RESULTS: LFS responder rates were 86.2%, 80.3%, and 65.3% at months 1 and 3 and 1 year, respectively, after initial/touch-up treatment. The responder rate improved to 94.3% 1 month after repeat treatment with VYC-15L and required less median volume vs initial/touch-up treatment (1.5 vs 2.6 mL). FACE-Q scores doubled from baseline at 3 months, remained high through 1 year, and doubled from baseline after repeat treatment. At 1 month after repeat treatment, 96.7% and 89.3% of subjects showed improvement over baseline in FACE-Q Satisfaction With Lips and Appraisal of Lip Lines, respectively. Severe injection site responses were less frequent after repeat treatment than initial/touch-up treatment. CONCLUSIONS: Repeat treatment with VYC-15L at 1 year was safe and effective for lip and perioral enhancement, and required less product volume to achieve similar effectiveness to initial/touch-up treatment.
