摘要

Objectives: Non-invasive facial rejuvenation has traditionally been based on layer-specific interventions targeting the skin, fat, and SMAS. However, clinical variability in contour improvement suggests limitations of this static, layer-based model. Materials / method: Through clinical experience with muscle-targeted high-intensity focused electromagnetic stimulation (HIFES), we observed morphological changes that cannot be explained by tissue contraction alone. Enhancement of muscle tone and function altered lifting vectors, influencing fat compartment positioning and fibroseptal tension, resulting in three-dimensional structural reorganization. Results: These findings suggest that facial rejuvenation should be understood not as isolated layer modification, but as reconstruction of an integrated, dynamic support system. Muscle-targeted intervention expands the role of device-based treatments beyond tissue tightening toward structural redesign. Conclusion: Facial rejuvenation is no longer defined by layer contraction, but by dynamic structural reconfiguration.
