BACKGROUND: Chin projection is a critical component of lower face aesthetics, influencing facial balance, youthfulness, and sexual dimorphism.
METHODS: This retrospective case series provides short-term, real-world observations on the use of Non-animal Stabilized Hyaluronic Acid - High Density (NASHA-HD™) injectable for chin augmentation as part of a combined lower-face hyaluronic acid (HA) filler treatment approach. Each patient received 1 mL of High-Animal Stabilized Hyaluronic Acid (HASHA™) administered as supraperiosteal boluses in the chin, distributed according to the patient's needs. For a comprehensive facial approach, complementary injections of HA fillers based on Optimal Balance Technology (OBT™)and NASHA®technologies were performed in the mid and lower face to harmonize facial proportions and enhance overall contour.
RESULTS: Results demonstrated high patient satisfaction, natural aesthetic outcomes, a natural look on the chin, and a favorable safety profile with only mild and transient adverse events. Independent Global Aesthetic Improvement Scale (iGAIS)-physician assessment demonstrated global aesthetic improvement and enhanced facial proportionality in most patients. This holistic approach achieved satisfactory projection and contour enhancement using low product volumes.
CONCLUSIONS: This article underscores the importance of using high G' fillers for structural support, and flexible fillers for dynamic zones, particularly in the diverse population, which presents a wide range of facial morphologies requiring personalized aesthetic approaches.
