Abstract (original English)

Poly-D,L-lactic acid (PDLLA) microspheres, marketed globally as Aesthefill ® (Regen Biotech, Seoul, South Korea), are recognized for their biocompatible and biostimulatory properties, positioning them as a preferred option in aesthetic medicine. This article presents consensus recommendations from Brazilian experts on the reconstitution and clinical application of PDLLA for facial and non-facial treatments. Developed using a modified Delphi method with contributions from leading dermatologists and plastic surgeons, the consensus outlines protocols for reconstitution, injection techniques, and patient management. Key recommendations include reconstitution with 7-8 mL of sterile water for injection, the addition of lidocaine to improve patient comfort, and a preference for targeting the superficial subcutaneous layer. Dosing guidelines are specifically tailored to each treatment area and the desired degree of correction, underscoring the importance of personalized treatment plans. Maintenance treatments are advised at biennial intervals or at shorter intervals for patients exhibiting accelerated collagen degradation. The consensus also highlights the need for proper training and patient screening to minimize adverse effects, such as nodules and granulomas. This comprehensive guide aims to standardize the use of PDLLA, prioritizing patient safety and optimizing outcomes. While cli
