Subject satisfaction and psychological well‐being with escalating abobotulinumtoxinA injection dose for the treatment of moderate to severe glabellar lines

A single ABO treatment (dosed at 50-125 U) provided significant and sustained improvements in glabellar line severity over durations up to 36 weeks, versus placebo. Treatment satisfaction was high with all doses. Participants reported natural and youthful appearance, alongside improvements in psychological well-being.
