Poly-l-lactic Acid Cone Threads–Silhouette Soft Threads—Patient Selection and Treatment Procedure

This chapter discusses the application of Silhouette Soft threads, a forefront innovation in aesthetic medicine, for facial rejuvenation and recontouring. Composed of biocompatible, biodegradable materials—poly-L-lactic acid (PLLA) and poly-L-glycolide (PLGA)—these resorbable sutures offer a novel approach to achieving a youthful and contoured facial appearance. The chapter provides an overview of the threads' material properties, mechanisms of action, and the biological process of resorption, highlighting their safety and efficacy for clinical use. It further explores the technique's application in lifting and redefining facial contours, detailing procedural steps, patient selection criteria, and post-procedure care. The chapter underscores the versatility of Silhouette Soft threads in addressing various signs of aging, such as mild-moderate soft tissue ptosis and loss of volume, thereby offering patients a minimally invasive option for facial enhancement.
