Outcome Measures
Primary Outcomes (12)
Percentage of Participants Assessed as At Least 1-point Improvement From Baseline on Medicis Lip Fullness Scale (MLFS)
The MLFS is a validated photograph-based outcome instrument that is designed specifically for quantifying lip fullness. Scoring of lip fullness from Grade 1 to 5 (grade 1: "Very Thin", grade 2: "Thin", grade 3: "Medium", grade 4: "Full" and grade 5: "Very Full"; with a higher score reflecting greater lip fullness) was based on visual live assessment by the Investigator. Percentage of participants with at least 1-point improvement from baseline on MLFS are reported for this outcome measure.
At Week 8

At Week 48
Change From Baseline on the MLFS by Treatment Area at Week 8 After the Last Injection
The MLFS is a validated photograph-based outcome instrument that is designed specifically for quantifying lip fullness. Scoring of lip fullness from Grade 1 to 5 (grade 1: "Very Thin", grade 2: "Thin", grade 3: "Medium", grade 4: "Full" and grade 5: "Very Full"; with a higher score reflecting greater lip fullness) was based on visual live assessment by the Investigator. Improvement was defined as at least 1-point change from baseline in lip fullness. Number of participants with no improvement, one grade, two grade and three grade improvement are reported for this outcome measure.
