- Canada is the first country to approve a new botulinum neurotoxin serotype for aesthetic use
- Boey® is the first and only rapid-onset and short-duration botulinum neurotoxin serotype E approved for the temporary improvement in the appearance of glabellar lines
- Boey® offers a differentiated treatment option for many people who are curious about facial injectables

- BOTOX Cosmetic® (onabotulinumtoxinA) is the only neurotoxin clinically tested for use following treatment with Boey®
IRVINE, Calif., June 23, 2026 /PRNewswire/ -- Today, Allergan Aesthetics, an AbbVie company (NYSE: ABBV), announced Health Canada has approved Boey® (trenibotulinumtoxinE) for the temporary improvement in the appearance of moderate to severe lines between the eyebrows (glabellar lines) in adult patients.
Boey® is the first and only rapid-onset and short-duration botulinum neurotoxin serotype E approved for the temporary improvement in the appearance of glabellar lines.
"Health Canada's approval of Boey® marks an important scientific and regulatory milestone in advancing toxin science. As the world's first approval of a botulinum neurotoxin based on serotype E in aesthetics, Boey® represents a meaningful advancement in aesthetic medicine - a fast-acting neurotoxin with a differentiated profile that expands the treatment options for clinicians and patients," said Roopal Thakkar, M.D., executive vice president, research and development, chief scientific officer, AbbVie.
A new Allergan Aesthetics survey found that 80% of people are open to learning about new treatments to get the results they want and 79% wish they could temporarily preview the outcome of an aesthetic treatment. 1 Despite growing interest in facial injectables, many patients are hesitant to take the next step due to uncertainty around treatment outcomes and committing to long-lasting results. Boey® was developed for these patients, offering a new way to experience neurotoxin treatment.
"Boey® represents an important new advancement for patients and healthcare professionals, addressing a key need in aesthetic neurotoxins. With its truly differentiated profile, Boey® is redefining aesthetics and expanding what's possible by giving practitioners another option to tailor treatment to individual needs and goals, specifically, the ability to try a toxin without the long-term commitment," said Nicole Mowad-Nassar, senior vice president, AbbVie and president, global Allergan Aesthetics. "Allergan Aesthetics is proud to bring this innovation to Canada first and to continue advancing options that help shape the future of aesthetic medicine."
Developed by the makers of BOTOX Cosmetic®, Boey® offers a new option for suitable patients considering facial injectables. BOTOX Cosmetic® is the only neurotoxin clinically tested for use following treatment with Boey®.
Allergan Aesthetics plans to begin training healthcare professionals on the appropriate use of Boey® and is preparing for a commercial launch in the upcoming months as trenibotulinumtoxinE is under review for approval in multiple other countries.
Allergan Aesthetics develops, manufactures and markets a portfolio of leading aesthetics brands and products. Allergan Aesthetics is well positioned to lead the future of injectable aesthetics, with dedicated research and development focused on driving innovation to meet the evolving needs of patients and healthcare professionals worldwide.

About the Boey® clinical studies
The approval of Boey® is supported by data from two randomised, multi-centre, double-blind, placebo-controlled studies Phase 3 clinical trials evaluating the efficacy and safety of Boey® in adults with moderate to severe glabellar lines (M21-500 and M21-508) associated with corrugator and/or procerus muscle activity. The studies enrolled 947 patients treated with Boey® 700 U total dose or placebo.
The primary efficacy measure was defined as the percentage of subjects achieving None or Mild and = 2-Grade Improvement from baseline in glabellar line severity at maximum frown based on both investigator and subject assessments using the Facial Wrinkle Scale (FWS) at Day 7. Efficacy was assessed in the ITT population. The composite responder rates at Day 7 were 60.0% and 65.7% (M2-500: n=289/482; M21-508: n=149/227; p<0.0001).
Secondary efficacy endpoints were measured by Facial Line Satisfaction Questionnaire (FLSQ), a validated scale developed by Allergan Aesthetics, and included satisfaction with achieving a natural look and overall satisfaction with treatment effect.
The onset of effect for patients treated with Boey® appeared as early as 8 hours after injection in both pivotal studies. Glabellar lines returned to baseline severity in approximately 14-21 days after administration.
The most frequently reported treatment-related adverse events were headache (3.4% in the Boey-treated group and 4.2% in the placebo-treated group), injection site pain (1.7% in the Boey-treated group and 2.9% in the placebo-treated group), and injection site erythema (0.6% in the Boey-treated group and 1.3% in the placebo-treated group).2

About Boey®
Boey® is a facial injectable neurotoxin serotype E indicated in adult patients for the temporary improvement in the appearance of of moderate to severe glabellar lines associated with corrugator and/or procerus muscle activity. It blocks neuromuscular transmission as the neurotoxin cleaves SNAP-25. It has a rapid uptake and translocation into neuronal cells, with a short half-life of the type E light chain, giving it a rapid onset of action and a short duration of effect when treating glabellar lines.2
About Glabellar lines
Glabellar lines are the vertical lines that appear between the eyebrows and are commonly referred to as "frown lines". These lines develop over time due to repeated muscle contractions from facial expressions such as frowning, concentrating or squinting.
