Background: AbobotulinumtoxinA has become well established as a treatment option for moderate to severe glabellar lines since its first aesthetic approval in 2009.

Objective: Pivotal trials leading to regulatory approval showed that abobotulinumtoxinA treatment was associated with high responder rates when defined as achievement of none or mild glabellar lines (0 or 1 on the glabellar line severity scale) and a duration of action of up to 5 months. More recently, the goals for treatment of glabellar lines have shifted toward not only achieving a decrease in glabellar line severity but also ensuring that patients are satisfied with their experience.
