This study is designed to evaluate the safety, efficacy, and subject and investigator satisfaction of 2 different injection volumes of Dysport in the glabellar lines. 1. To determine the proportion of composite responders (based on blinded evaluator and subject assessments) who achieve at least a 1-point reduction from baseline in glabellar line severity score (GLSS) at maximum frown line on Day 30. 2. To assess the GLSS, at maximum frown and at rest, by live assessment at all visits. 3. To evaluate the onset of effect on appearance of glabellar lines starting at the Day 2 visit (subject and blinded evaluator). 4. To assess the subject's satisfaction with the treatment. 5. To evaluate investigator satisfaction of treatment outcome. 6. To evaluate subject psychological well-being. 7. To evaluate subject age appraisal. 8. To evaluate all adverse events during the course of the study.
Five month, randomized, subject- and evaluator-blinded, multi-center, mult-visit study. Subjects treated with Dysport following the US on-label guidelines.

Time frame: 30 days
Proportion of Responders, at Maximum Frown (Subject)
Proportion of responders, at maximum frown, with GLSS at least 1-point reduction from baseline on days 2, 3, 4, 7, 14, 30, 90 and 120 based on assessments by subject using a static 4-point categorical (subject) scale.
Time frame: 120 days
Proportion of Responders, at Maximum Frown (Blinded Evaluator)
Proportion of responders, at maximum frown, with GLSS at least 1-point reduction from baseline on days 2, 3, 4, 7, 14, 30, 90 and 120 based on assessments by blinded evaluator using a validated 4-point photographic scale.

Proportion of responders, at rest, with GLSS at least 1-point reduction from baseline on days 2, 3, 4, 7, 14, 30, 90 and 120 based on assessments made by blinded evaluator using a validated 4-point photographic scale.
Time frame: 120 days
Proportion of Responders, at Rest (Treating Investigator)
Proportion of combination responders, at rest, with GLSS at least 1-point reduction from baseline on days 2, 3, 4, 7, 14, 30, 90 and 120 based on assessments made by treating investigator using a validated 4-point photographic scale.
Time frame: 120 days
Proportion of Combination Responders, at Rest (Blinded Evaluator and Subject)
Proportion of combination responders, at rest, with GLSS at least 1-point reduction from baseline on days 2, 3, 4, 7, 14, 30, 90 and 120 based on assessments made by blinded evaluator and subject.

Proportion of Subjects Who Achieved an Onset of Effect on the Appearance of the Subject's Glabellar Lines.
Combination endpoint from both subject and blinded evaluator assessments. Assessments made on days 2, 3, 4, and 7.
Time frame: 7 days
Subject Satisfaction With the Treatment of Glabellar Lines - I am Satisfied With How I Look.
Proportion of subjects who responded 'agree' or 'strongly agree' regarding change from baseline in subject satisfaction questionnaire on day 120.
Time frame: 120 days
Investigator Satisfaction With Treatment Outcome - Satisfied With the Study Product Results
Proportion of treating investigators who responded 'agree' or 'strongly agree' to the individual satisfaction questions on Day 30.
Time frame: 30 days
Subject Psychological Well-being - Mean Change at Day 120 Compared to Baseline
Mean change from baseline on day 120 using the Psychological Well-Being (FACE-Q).Total score for entire questionnaire is transformed to a Rasch score, scale of 0-100. Increase in score = increased well-being.
Time frame: Baseline and Day 120
Subject Age Appraisal Using the FACE-Q-Age Appraisal Visual Analog Scale (VAS) - Mean Change at Day 120 Compared to Baseline
Mean change from baseline on day 120 using the FACE-Q Age Appraisal VAS. "0" years represents "current age subjects rated their appearance as older or younger than current age"; "+" years represents "older than current age"; "-" years represents "younger than current age".
Time frame: Baseline and Day 120
Subject Appraisal of Lines Between the Eyebrows (FACE-Q) - Mean Change at Day 120 Compared to Baseline
Mean change from baseline on day 120 using the Subject Appraisal Lines Between the Eyebrows (FACE-Q).Total score for entire questionnaire is transformed to a Rasch score, scale of 0-100. Increase in score = less bothered by glabellar lines.
Time frame: Baseline and Day 120
