Dermal Filler Science: Material Types, Rheology & Hyaluronic Acid Formulations

The second lesson shifts to aesthetic facial proportions and the biophysics of dermal fillers. You will study classical concepts of facial beauty, the Golden Ratio, the Triangle of Beauty, and the Pyramid of Aging. The lesson provides an in-depth analysis of soft-tissue filler materials, contrasting resorbable and non-resorbable fillers (including CaHA and PLLA). Finally, you will master Hyaluronic Acid (HA) science, cross-linking technologies, rheological properties ($G'$, elasticity, viscosity), and specific clinical range profiles such as Juvéderm Vycross (Voluma, Volift, Volbella).
