Outcome Measures
Primary Outcome Measures
- The reduction of glabellar lines [3 months]
The reduction of glabellar lines will be assessed by a panel of 3 independent reviewers with expertise in dermatology and/or plastic surgery of the change in glabellar lines measured from baseline to 3, 6, 9 and 12 months post procedure. Photographs will be presented in a random order and the reviewers will be blinded to whether the photograph is baseline or a follow up. Effectiveness of the procedure is defined by a ≥ 1 point improvement in score (i.e., numerical decrease) on the Mertz Aesthetics Scale™ (Merz Scale) for dynamic glabellar lines. At each time point the severity of the glabellar lines is assessed on a 5 point scale.
Secondary Outcome Measures
- Incidence and severity of adverse events [3 months]
- The reduction of glabellar lines [12 months]
The reduction of glabellar lines will be assessed by a panel of 3 independent reviewers with expertise in dermatology and/or plastic surgery of the change in glabellar lines measured from baseline to 3, 6, 9 and 12 months post procedure. Photographs will be presented in a random order and the reviewers will be blinded to whether the photograph is baseline or a follow up. Effectiveness of the procedure is defined by a ≥ 1 point improvement in score (i.e., numerical decrease) on the Mertz Aesthetics Scale™ (Merz Scale) for dynamic glabellar lines. At each time point the severity of the glabellar lines is assessed on a 5 point scale.
- Subject satisfaction [12 months]
Subject satisfaction will be assessed by a survey given every 3 months. This survey asks the subject questions to rate on a scale of 0-4 with 0 representing very dissatisfied and 4 representing very satisfied.
