• Boey^® is the first and only rapid-onset and short-duration botulinum neurotoxin serotype E approved in Europe that adult patients can try for the temporary improvement of glabellar lines¹
• Results may be seen as early as eight hours after treatment and typically wear off within approximately two to three weeks
• Boey^® offers a differentiated treatment option for many people who are curious about facial injectables²

NORTH CHICAGO, Ill., July 17, 2026 /PRNewswire/ -- Allergan Aesthetics, an AbbVie company (NYSE: ABBV), announced the European Commission has approved Boey^® (trenibotulinumtoxinE) in Europe, for the temporary improvement in the appearance of moderate to severe lines between the eyebrows seen at maximum frown (glabellar lines) in adult patients, when these have an important psychological impact.¹

Following completion of the centralized procedure, the European Commission decision applies across all 30 European Economic Area (EEA) countries. Boey^® also received approval in Canada in June of this year.

Boey^® is the first and only rapid-onset and short-duration botulinum neurotoxin serotype E approved in Europe. In clinical studies, onset of effect was observed as early as eight hours after treatment and effects lasted two to three weeks.

"The EU approval of Boey^® marks an important step forward for our development program and builds on the momentum we've established with Health Canada's approval earlier this year," said Darin Messina, Ph.D., senior vice president, aesthetics research & development, AbbVie. "This milestone reflects the scientific rigor behind Boey® and reinforces our commitment to advancing innovative options as we work to bring this first-of-its-kind treatment to healthcare professionals and consumers around the world."

As interest in aesthetic treatments continues to grow, patients are increasingly seeking treatment options that align with their individual goals and preferences. An Allergan Aesthetics survey found that 80% of people are open to learning about new treatments to achieve their desired results, while 79% wish they could temporarily preview the outcome of an aesthetic treatment.^3,* Despite this growing interest, many patients remain hesitant to take the next step due to uncertainty around treatment outcomes and concerns about committing to long-lasting results. Boey^® was developed for patients considering treatment, offering another option to experience it before making a longer-term commitment.

Developed by the makers of BOTOX Cosmetic^®, known as VISTABEL^® or Vistabex^® in the EU, Boey^® offers a new option for suitable patients considering facial injectables. BOTOX Cosmetic^® is the only neurotoxin clinically tested for safety following treatment with Boey^®.¹

Allergan Aesthetics is preparing to launch Boey^® across Europe and will support healthcare professionals through education and training on the appropriate use of Boey^®.

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.

BOTOX^® COSMETIC US APPROVED USES AND IMPORTANT SAFETY INFORMATION
BOTOX^® Cosmetic is a prescription medicine that is injected into muscles and used to temporarily improve the look of moderate to severe forehead lines, crow's feet lines, frown lines between the eyebrows, and vertical bands connecting the jaw and neck (platysma bands) in adults.

IMPORTANT SAFETY INFORMATION

BOTOX^® Cosmetic may cause serious side effects that can be life threatening. Get medical help right away if you have any of these problems any time (hours to weeks) after injection of BOTOX^® Cosmetic:

Problems swallowing, speaking, or breathing, due to weakening of associated muscles, which can be severe and result in loss of life. You are at the highest risk if these problems are preexisting before injection. Swallowing problems may last for several months.

Spread of toxin effects. The effect of botulinum toxin may affect areas away from the injection site and cause serious symptoms, including loss of strength and all-over muscle weakness, double vision, blurred vision and drooping eyelids, hoarseness or change or loss of voice, trouble saying words clearly, loss of bladder control, trouble breathing, and trouble swallowing.

BOTOX^® Cosmetic dosing units are not the same as, or comparable to, any other botulinum toxin product.

This list may not include all available botulinum toxin products.

Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Using BOTOX^® Cosmetic with certain other medicines may cause serious side effects.

Tell your doctor if you have received any other botulinum toxin product in the last 4 months; have received injections of botulinum toxin such as Myobloc, Dysport, Xeomin, Jeuveau, Daxxify, or Letybo in the past (tell your doctor exactly which product you received); have recently received an antibiotic by injection; take muscle relaxants; take an allergy or cold medicine; take a sleep medicine; or take aspirin-like products or blood thinners.

About Boey^®
Boey^® is a facial injectable neurotoxin serotype E that targets 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.

About Boey^® Clinical Trials
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, who were psychologically impacted by their glabellar lines. The studies enrolled 725 patients treated with Boey^® 700 U total dose or placebo. The co-primary efficacy measure (treatment effect) was defined as the percentage of subjects achieving a ≥2-grade improvement from baseline in glabellar line severity at maximum frown based separately on investigator and subject assessments using the 4-point Facial Wrinkle Scale (FWS) (0=none, 1=mild, 2=moderate, 3=severe) at Day 7. Efficacy was assessed in the ITT population with baseline FLO-11 Total Transformed Score of ≤50. Secondary efficacy endpoints were measured by FLSQ, a scale developed by Allergan Aesthetics, and included satisfaction with achieving a natural look (Item 4) and overall satisfaction with treatment effect (Item 5).

The onset of effect for patients treated with Boey® appeared as early as 8 hours after injection in both pivotal studies. The peak effect was seen at Day 7 in both studies. Glabellar lines returned to baseline severity in approximately 2 to 3 weeks after administration.

The adverse drug reactions associated with Boey^® were eyelid ptosis, brow ptosis, and Mephisto sign (lateral elevation of eyebrow). These reactions were reported in 0.17%, 0.13%, and 0.04%, respectively, in subjects receiving Boey^® 700 units.¹

About Glabellar Lines
Glabellar lines are the vertical lines that appear between the eyebrows, commonly known as frown lines. In some adults, these lines can contribute to an appearance that is perceived as tired, angry or worried and may have an important psychological impact.
