Abstract:
Hyaluronic acid (HA) fillers have many favorable characteristics that make it a popular injectable filler device. Its minimal immunogenicity and relative ease of use has helped HA become the most commonly used injectable filler today. A brief history of injectable fillers, the various injection techniques, and legal ramifications are discussed. A review of the most recent literature compares the efficacy and safety of HA to other injectable filler substances.
