Hyaluronic acid (HA) fillers are increasingly used for minimally invasive facial rejuvenation to address age-related volume loss and contour changes. Technologies such as non-animal stabilized HA (NASHA) for firm structural support and optimal balance technology (OBT) for flexible, movement-adaptable refinement are esthetically used. Selecting the right formulation based on anatomy is essential. This case series highlights how both NASHA and OBT range of fillers are selected for optimizing jawline, chin, and lip enhancement. 5 adult females (aged 24–55 years) presented with lower-face and lip concerns. Baseline assessments employed the Medicis Lip Fullness Scale, Jawline Subject Satisfaction Scale, FACE-Q, and Global Aesthetic Improvement Scale. Treatment used NASHA (high G') for projection, moderate G' OBT for contour refinement, and low G' OBT for lip enhancement. Jawline and chin cases showed improved structure and definition, while lip cases achieved fuller, more symmetrical, youthful lips, with no adverse events. This series supports formulation-based HA filler selection for natural, balanced lower-face rejuvenation.
