Exploring the Safety and Satisfaction of Patients Injected With Collagen Biostimulators-A Prospective Investigation Into Injectable Poly-l-Lactic Acid (PLLA).

Background: Esthetic medicine has shifted significantly toward non-surgical procedures, with the collagen biostimulator poly-l-lactic acid (PLLA) becoming increasingly popular for facial rejuvenation. However, the safety and patient satisfaction associated with PLLA facial treatments remain largely unexplored.

Objective: This study aimed to evaluate the safety profile of PLLA treatment and assess patient mid- and long-term satisfaction with the outcome.
