European Commission approves Boey (trenibotulinumtoxinE), the first serotype E neurotoxin in Europe
Allergan Aesthetics announced on 17 July 2026 that the European Commission has approved Boey (trenibotulinumtoxinE) across all 30 EEA countries for the temporary improvement of moderate to severe glabellar lines in adults where these have an important psychological impact. It is the first rapid-onset, short-duration botulinum neurotoxin serotype E licensed in Europe, with onset observed as early as eight hours and effect typically resolving within two to three weeks; approval follows Health Canada authorisation in June 2026. Harley Street Institute has published a review explaining why serotype E duration is set by its SNAP-25 cleavage site and light-chain persistence rather than by dose.
