Hyaluronics for Soft-Tissue Augmentation: Practical Considerations and Technical Recommendations

Hyaluronic acid (HA) fillers are long chains of sugar molecules. Depending on various physical properties, such as chain length and cross-linking, they can have different textures and durations. Injections of hyaluronic acids for soft-tissue augmentation is one of the most popular procedures performed in the U.S., Europe, Asia and Canada. With the development of newer HA molecules, it is likely that this trend will continue. Choosing the right HA for a particular patient depends on various factors, including the area to be treated, skin thickness and patients’ risk tolerance. Understanding the various molecules, and how they interact, is essential for ensuring optimal patient outcomes.
