Injectable Filler-Based Chin Augmentation: A Systematic Review of Non-Surgical Volumetric Techniques

Area of Science:

• Aesthetic Medicine
• Dermatology
• Plastic Surgery

Background:

• The chin significantly impacts facial aesthetics, harmony, and perceived attractiveness.
• Retrusion of the chin can negatively affect facial balance and self-perception.
• Minimally invasive cosmetic procedures, including nonsurgical chin augmentation, are increasingly popular.

Purpose of the Study:

• To systematically review injectable volumetric techniques for chin augmentation.
• To focus on dermal filler-based interventions for chin augmentation.
• To synthesize evidence on the efficacy, safety, and patient satisfaction of these procedures.

Main Methods:

• A systematic review following PRISMA-E guidelines.
• Comprehensive search of seven databases (1965-2026).
• Analysis of study quality, data diversity, and heterogeneity (I²).

Main Results:

• Eleven studies with 876 patients were analyzed.
• Hyaluronic acid fillers were predominantly used, with average follow-up of 12.8 months.
• Over 90% patient satisfaction reported; adverse effects were minor and transient (e.g., edema, bruising).

Conclusions:

• Injectable fillers provide effective short-term chin augmentation with high patient satisfaction and acceptable safety.
• Current evidence is heterogeneous and largely non-comparative, limiting long-term outcome conclusions.
• Further controlled studies are necessary to evaluate long-term efficacy and safety.
