Abstract
Background: The current study evaluated the effectiveness and safety of Sculptra injectable poly-L-lactic acid (PLLA-SCA) treatment in correcting cheek wrinkles compared with a no-treatment control.
Methods: Male/female immune-competent adults (aged >21 years) with moderate/severe cheek wrinkles, graded using the Galderma Cheek Wrinkle Scale (GCWS) at rest, were randomized 2:1 to receive PLLA-SCA injections (150 mg; 8 mL reconstitution in sterile water for injection) + 1 mL lidocaine hydrochloride (2%), administered immediately after reconstitution, or no treatment (control). Up to 3 additional treatments were allowed at monthly intervals, and follow-up was at months 7, 9, and 12. The primary endpoint was 1-grade or greater improvement in GCWS at rest for both cheeks at month 12.
Results: GCWS at rest responder rate was significantly higher with PLLA-SCA treatment versus the no-treatment control at months 7 (66.2% versus 38.6%; P=0.0043), 9 (70.6% versus 31.1%; P<0.0001), and 12 (71.6% versus 26.1%; P<0.0001). Treating investigators reported improvements in skin radiance (>95%), tighter appearance (>88%), and jawline contour (>85%). PLLA-SCA recipients reported high satisfaction levels regarding improvements in skin radiance (90% or greater), sagging (84% or greater), and firmness (91% or greater) as well as natural-looking results (85% or greater) and a desire for repeat treatment (84% or greater). Treatment-related adverse events were mostly mild in severity with no serious events related to PLLA-SCA injections.
Conclusion: Injectable PLLA-SCA treatments were well tolerated and significantly reduced the severity of moderate/severe cheek lines and wrinkles, while improving skin quality. Effectiveness was durable over the 12-month study period with high subject-reported satisfaction, natural-looking appearance, and enthusiasm for repeat treatments.

INTRODUCTION

Sculptra poly-L-lactic acid injectable implant (PLLA-SCA; Galderma, Sweden) is a plant-derived alpha-hydroxy-acid polymer.1-4  When used for soft tissue augmentation, PLLA-SCA gradually stimulates collagen formation, over the course of several treatments, to provide semi-permanent correction of facial volume loss associated with aging.1-4 

Injectable PLLA-SCA has demonstrated durable and natural looking results in randomized studies, with most recipients (80%) maintaining aesthetic correction of contour deficiencies until the 25-month data cut-off.5,6 Growing experience has driven an improved understanding of optimal PLLA-SCA injection techniques to achieve high levels of treatment satisfaction and good safety outcomes.2,7-9 PLLA-SCA studies
