Breaking down the facts behind Hannah Berner’s Dysport Mishap Explained: Risks, Recovery, and Safe Jaw Botox Tips—read on to discover what experts are saying.

Masseter injections for TMJ, bruxism, and jaw contouring remain technically off-label under FDA guidelines, though they are widely performed globally. Because the procedure is off-label, practitioner standards vary dramatically depending on clinic governance.

Board-certified dermatologists and plastic surgeons adhere to strict anatomical boundary rules to prevent risorius paralysis:

• Injections must stay strictly within the lower posterior quadrant of the masseter. Injectors map an imaginary line from the earlobe (tragus) to the corner of the mouth; needle sticks must remain well below this line.
• Perpendicular Deep Placement: The product must be injected straight into the deep belly of the muscle against the mandibular bone, not deposited within superficial dermal layers where the risorius rests.
• Starting with conservative doses (around 20 to 30 units of Botox or 50 to 75 units of Dysport) allows clinicians to assess baseline response before administering touch-ups.
• Post-Care Restrictions: Rubbing the jaw, lying down immediately, or utilizing firm facial massage tools within 24 hours can physically push the neurotoxin into adjacent motor zones.

Selecting an injector requires screening beyond pricing promotions or social media aesthetics. Practitioners must possess comprehensive anatomical credentials to navigate individual muscle variations.
