How Does Injecting Filler Into Facial Ligaments Result in Facial Lifting?

The lifting effect of filler injection arises from a synergistic mechanism that combines volumetric restoration with biomechanical reinforcement of fibrous anchoring structures. Understanding the regional variability and mechanical behavior of facial ligaments enables anatomy-based, low-volume rejuvenation strategies that preserve natural dynamics. Further clinical and quantitative biomechanical studies are warranted to validate these observations under physiological conditions.
