Hyaluronic Acid (HA)
Injection TreatmentsA naturally occurring polysaccharide used as the base of dermal filler gels.
Hyaluronic acid is a natural component of skin and joint fluid with very high water-binding capacity. In aesthetics, cross-linked HA gels are used as fillers in lip, midface, jawline, tear-trough, and nose. Rheological properties (G-prime, cohesivity) drive zone selection.
