A Randomized, Multicenter, Evaluator-blind Study to Evaluate the Safety and Effectiveness of VYC-12L Treatment for Skin Quality Improvements

Abstract

BACKGROUNDSkin quality may be assessed by degrees of skin smoothness, fine lines, and hydration. VYC-12L is a recently developed hyaluronic acid filler to improve skin quality.OBJECTIVEThis was a randomized, evaluator-blind study assessing safety and effectiveness of intradermal VYC-12L treatment for improving cheek skin smoothness, fine lines, and hydration.METHODSParticipants (≥22 years) with moderate-to-severe investigator-assessed Allergan Cheek Smoothness Scale (ACSS) scores were randomized in 2:1 ratio to receive VYC-12L or control (no treatment with optional treatment). Effectiveness was assessed 1 month after last injection (initial or touch-up) by a responder rate (≥1-grade improvement from baseline on both cheeks) using investigator-rated ACSS and Allergan Fine Lines Scale (AFLS), and tissue dielectric constant probe-measured skin hydration. Safety was evaluated throughout.RESULTSParticipants (VYC-12L, n = 131; control, n = 71) were 86.1% female with a median age of 58.0 years. At month 1, ACSS and AFLS responder rates were statistically significantly higher in the VYC-12L group (57.9%, 58.3%, respectively) than in the untreated controls (4.5%, 5.4%, respectively; p
