Objectives: To explore the application effect and safety of poly-l-lactic acid (PLLA) facial thread lifting in facial rejuvenation. Introduction: Facial rejuvenation techniques are continuously evolving, with thread lifting gaining popularity as a minimally invasive option. Poly-L-Lactic acid (PLLA) threads are widely used, but a comprehensive understanding of their application effect and safety profile in facial rejuvenation is essential. Materials / method: The clinical data of 46 beauty seekers who received PLLA facial thread lifting treatment at our hospital from March 2022 to June 2024 were retrospectively selected. All individuals underwent PLLA facial thread lifting. The improvement of facial contour, changes in skin texture, and occurrence of complications before and after treatment were statistically analyzed. Results: All patients achieved good facial rejuvenation effects after surgery. The facial contour was significantly lifted, wrinkles were reduced, and skin texture was improved. The incidence of postoperative complications was low, mainly including local swelling, pain, and congestion, which all spontaneously resolved in a short period. Conclusion: PLLA facial thread lifting is a safe and effective facial rejuvenation treatment method. It offers advantages of simple operation, remarkable effect, minimal trauma, and quick recovery, making it worthy of clinical promotion and application.
