Design outcomes

Primary

MeasureTime frameDescription
Percentage of Participants Achieving None or Mild on the Investigator's Assessment of the Severity of Crow's Feet Lines (CFL) at Maximum Smile Using the Facial Wrinkle Scale-Asian (FWS-A)Day 30The Investigator assessed the severity of the patient's Crow's Feet lines at maximum smile using the 4-point Facial Wrinkle Scale where 0=none, 1=mild, 2=moderate or 3=severe. The percentage of participants with a score of none or mild at Day 30 is reported.

Secondary

MeasureTime frameDescription
Percentage of Participants Achieving a ≥1-Grade Improvement From Baseline on the Investigator's Assessment of the Severity of CFL at Rest Using the FWS-ADay 30The Investigator assessed the severity of the participant's Crow's Feet Lines at rest using the 4-point Facial Wrinkle Scale where 0=none, 1=mild, 2=moderate or 3=severe. The percentage of participants with a ≥1-grade improvement from Baseline at Day 30 is reported.
Percentage of Participants Much Improved or Very Much Improved in the Subject's Assessment of Appearance of CFL as Measured by the Global Assessment of Change in Crow's Feet LinesDay 30Participants rated the change in their Crow's Feet Lines using the Subject's Global Assessment of Change in Crow's Feet Lines (SGA-CFL) 7-point scale where 1=very much improved, 2=much improved, 3=minimally improved, 4=no change, 5=minimally worse, 6=much worse or 7=very much worse. The percentage of participants who reported Much Improved or Very Much Improved at Day 30 is reported.
Percentage of Participants Who Rate Themselves in a Younger Self-Perception of Age Category Than at BaselineDay 30Participants were considered to judge themselves as looking younger if the category change was from look my current age at Baseline to look younger at Day 30 or from look older at Baseline to look my current age/younger at Day 30.
