Current Landscape of Hyaluronic Acid Filler Use in the United States.

Overview

BACKGROUND: Hyaluronic acid (HA) fillers are among the most used fillers for soft-tissue augmentation. There are now many FDA-approved HA products, and the successful use of injectable HA fillers requires an understanding of the available options. Objective: The purpose of this manuscript is to provide a comprehensive list of HA fillers and their indications. An overview of their biochemical properties and formulations will aid dermatologists in appropriate use. METHODS: A comprehensive search of all the FDA-approved dermal fillers was conducted via the FDA "pre-market approval" (PMA) site. Additional details regarding filler properties were obtained using the respective agent's package inserts. Results: A total of 28 HA dermal fillers were identified and key pharmaceutical properties were discussed. These findings will help the physician match the appropriate HA filler with the area that is to be treated. Conclusion: Understanding the available fillers and their properties can help physicians select the appropriate fillers for more predictable and sustainable results.
