First neurotoxin indication for masseter prominence; exclusive if approved.
Masseter prominence—often called "square jaw" or mandibular hypertrophy—is a growing aesthetic category, particularly among younger patients seeking jawline refinement without surgery. If approved, BOTOX Cosmetic will own this indication exclusively among toxins. For practices, this represents a new revenue stream and a competitive advantage for AbbVie in the toxin portfolio. Expect marketing support and potential Allē rebate incentives tied to this indication once approved. Practices should begin training staff on patient selection and injection technique now.
