Abstract

Introduction: Over time, the skin and subcutaneous tissues gradually lose their natural elasticity and are continuously affected by gravity. Various aging signs appear, such as sagging, skin laxity, and numerous wrinkles, particularly deep wrinkles, which significantly impact facial aesthetics. As a result, the demand for improving facial sagging has been increasing. Thread lifting is a minimally invasive procedure with several advantages, including quick execution time, minimal recovery period, immediate visible results, and no scarring. Nowadays, patients tend to choose thread lifting as a preferred treatment for facial aging. In Vietnam, thread lifting has been widely applied over the past 4–5 years. However, no comprehensive studies have been conducted to evaluate its effectiveness and safety. Objective: This study aims to assess the safety, efficacy, and patient satisfaction after performing absorbable barbed PDO thread lifting (White Medience Co., LTD., Korea). Subjects and Methods: A descriptive study was conducted on 30 clinical cases of facial aging with mild to moderate sagging (grades 2–3 according to the Melvin A. Shiffman classification) treated with absorbable barbed PDO threads at HCMC Hospital of Dermato Venereology from September 2023 to December 2023. The improvement was evaluated at different time points: immediately after the procedure, at 2 weeks, 1 month, and 3 months, using Fitzpatrick MFWS, WSRS-MLGS, and GAIS scales. Results: Facial sagging significantly improved (p < 0.001) and remained stable during the first 3 months. After 6 months, mild sagging reappeared. Facial symmetry was enhanced post-procedure. The GAIS score remained at 4 or higher within the first 3 months and slightly declined after 6 months. There was no significant difference in satisfaction levels between patients and physicians (p > 0.05). The complication rate was low (20%), mainly including mild skin bulging and dimpling, with no severe complications recorded. Conclusion: Absorbable PDO thread lifting is a safe and effective method for patients with mild to moderate facial sagging, with no severe complications observed post-procedure. Further studies with larger sample sizes and extended follow-up periods are necessary to evaluate long-term efficacy and monitor potential late-onset complications
