OnabotulinumtoxinA & 100 U Toxins: Nomenclature, Dilution & Regional Mapping

The second lesson focuses on OnabotulinumtoxinA and equivalent 50 U and 100 U formulations (Vistabel, Botox, Bocouture, Letybo, Nuceiva). You will review neurotoxin nomenclature across chemical, generic, and brand names alongside key published studies. The lesson provides step-by-step reconstitution guidelines for 50 U and 100 U vials, including specific 1-point dilution techniques. You will examine upper-face anatomical landmarks, identify forbidden forehead injection zones, analyze glabellar movement patterns, and map orbicularis oculi caution areas for consistent clinical safety.
