Botulinum toxin A (BoNTA) is produced by Clostridium botulinum and widely used for aesthetic indications requiring neuromuscular blockade. For dynamic facial lines, BoNTA is effective and safe, but also temporary, requiring repeat injections approximately every 3-4 months for maintenance of effects. There is a desire by both patients and providers for a longer-lasting neurotoxin to prevent periods of suboptimal correction. Approved by the US Food and Drug Administration (FDA) in September 2022, daxibotulinumtoxinA for injection (DAXI or Daxxify™) is the first long-lasting BoNTA formulated with a 150-kDa BoNTA (RTT150) and proprietary stabilizing excipient peptide (RTP004) in place of human serum albumin. DAXI is approved for treatment of moderate to severe glabellar lines. The median duration of effect was 6 months and results lasted as long as 9 months in some patients. Its unique formulation and prolonged effectiveness positions DAXI as a safe, novel BoNTA for improved durability and patient satisfaction.
