Objectives: This study aims to evaluate the effects of lip enhancement using hyaluronic acid (HA) filler injections, utilizing AI-based tools for objective, data-driven analysis. It will assess changes in lip volume and their impact on overall facial aesthetics, including perceived age, emotional expressions, and facial balance. By leveraging AI, the study seeks to develop a more holistic framework for lip enhancement assessments, moving beyond traditional subjective evaluations to offer more precise, quantifiable insights into the effects of HA fillers on facial appearance.
Introduction: The lips are a popular area for filler treatments across all age groups. Existing evaluations of lip volume enhancement often rely on subjective, visual assessments and fail to account for the overall facial balance and aesthetic changes. To address this, this study uses various AI models for a comprehensive analysis to better evaluate the effects of lip enhancement and provide insights for patient-specific treatment plans.
Materials / method: This study involved 31 participants (29 females, 2 males), all of whom received lip HA filler injections. Pre- and post-treatment facial images were captured in a relaxed state, and these images were processed using AI-based tools to record and analyze facial visual analysis, perceived age, and emotional expressions displayed on the face.
Results: Post-treatment, The Facial Visualization Analysis revealed that as lip volume increased, the lip line became more defined and the natural curve of the lips became more balanced. The MiVOLO model demonstrated high age estimation accuracy (MAE: 5.15; ICC:0.866; Pearson’s r: 0.875), with a mean apparent age reduction of −1.63 ± 2.51 years (95% CI = -2.78 to -0.49, Cohen's d = -0.65), emotion analysis revealed a significant increase in neutral expression (72.97% to 83.44%, 95% CI = 3.38 to 17.56, Cohen's d = 0.58) and reductions in anger (10.25% to 5.84%, 95% CI = −8.53 to −2.28, Cohen's d = -0.42
Conclusion: This study provides significant insights by showing that lip volume improvement affects not only external changes but also emotional expression, age perception, and social interaction. This approach presents a new solution in the field of cosmetic surgery and will contribute to improving patient satisfaction through personalized treatments and multifaceted effect analysis.
