What is being measured
The primary outcome is the main question the study is designed to answer.

The Merz aesthetics scales (MAS) are 5-point scales used to identify responders in a clinical context. They are validated photograph-based outcome instruments designed specifically for assessment of each upper facial area. GFL-response was defined as a score of 0 (no) or 1 (mild) and at least two-grade improvement from baseline to Day 30 of main period on MAS for GFL at maximum contraction as assessed by both the investigator and the subject. The MAS for GFL ranged as 0 to 4 where 0 is "No glabellar lines", 1 is "Mild glabellar lines", 2 is "Moderate glabellar lines", 3 is "Severe glabellar lines" and 4 is "Very severe glabellar lines".

The Merz aesthetics scales (MAS) are 5-point scales used to identify responders in a clinical context. They are validated photograph-based outcome instruments designed specifically for assessment of each upper facial area. GFL-response was defined as a score of 0 (no) or 1 (mild) and at least two-grade improvement from baseline to Day 30 of main period on MAS for GFL at maximum contraction as assessed by both the investigator and the subject. The MAS for GFL ranged as 0 to 4 where 0 is "No glabellar lines", 1 is "Mild glabellar lines", 2 is "Moderate glabellar lines", 3 is "Severe glabellar lines" and 4 is "Very severe glabellar lines".
