AbbVie's Allergan Aesthetics has secured European approval for Boey (trenibotulinumtoxinE), a rapid-onset, short-duration neurotoxin indicated for glabellar frown lines. Boey's differentiation lies in onset speed and duration profile—a distinct clinical positioning versus Botox (onset 3–7 days, duration 12+ weeks) and Dysport (faster onset, variable duration).
Allergan Aesthetics Wins EU Approval for Boey — First Rapid-Onset, Short-Duration Neurotoxin Reshapes Toxin Economics
Boey (trenibotulinumtoxinE) becomes the first rapid-onset, short-duration neuromodulator approved in Europe, fragmenting the toxin market.

Boey's rapid-onset, short-duration profile fragments the toxin market and signals AbbVie's defense against Revance and Evolus.
For US medspa owners, Boey's EU approval signals AbbVie's intent to fragment the toxin market and defend share against Revance's Daxxify (long-acting) and Evolus's Jeuveau (aggressive rebate pricing). A rapid-onset, short-duration product appeals to patients seeking trial treatments or frequent touch-ups, creating new per-unit volume opportunities—but also cannibalization risk within a practice's existing Botox/Dysport patient base. Watch for US FDA filing; if approved, expect aggressive Alle rebates and MSO bundling to drive adoption.
