Background:Juvéderm Volbella with Lidocaine is a new hyaluronic acid dermal filler.Methods:In this prospective, randomized, multicenter study, 280 subjects desiring lip volume enhancement were treated with Juvéderm Volbella with Lidocaine or Restylane-L. Investigators rated treatment outcomes on Allergan’s Lip Fullness Scale, Perioral Lines Scale, and Oral Commissures Severity Scale. A blinded independent central reviewer (ICR) assessed 3-dimensional digital photographs using these scales. Subjects evaluated outcomes using the FACE-Q Recovery Early Life Impact and Recovery Early Symptoms modules. The primary endpoint was noninferiority of Juvéderm Volbella with Lidocaine to Restylane-L based on responder rate (percentage of subjects with ≥1-point Lip Fullness Scale improvement at month 3 ICR assessment vs baseline).Results:Juvéderm Volbella with Lidocaine was noninferior to Restylane-L. Although responder rates based on ICR assessments of lip fullness, perioral lines, and oral commissures did not differ between treatments, investigator assessments showed significant improvements in perioral lines and oral commissures with Juvéderm Volbella with Lidocaine vs Restylane-L (P ≤ 0.029). Subjects treated with Juvéderm Volbella with Lidocaine had higher mean FACE-Q scores on day 1 (P ≤ 0.001), indicating less disruption of daily activities. Mean change in lip volume from baseline to day 1 was smaller in the Juvéderm Volbella with Lidocaine group (but similar between treatments on day 14), indicating less acute swelling. Severe injection site responses occurred less frequently with Juvéderm Volbella with Lidocaine.Conclusions:Juvéderm Volbella with Lidocaine is effective for lip enhancement, improves perioral lines and oral commissures, and results in less short-term swelling and disruption in daily activities than Restylane-L.
