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 participant'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.

MeasureTime frameDescription
Percentage of Participants With a ≥2-Point Improvement From Baseline for Facial Line Outcomes Questionnaire (FLO-11) Item 2 at Day 30Baseline, Day 30The FLO-11 questionnaire is comprised of 11 items that assess the subject's perceptions about specific aspects of their facial lines for the previous 7 days. Each question was scored on an 11-point scale (0=not at all, 5=somewhat, 10=very much). FLO-11 responders were defined as the percentage of participants with a ≥2-point improvement from Baseline in FLO-11 Item 2 : When I look in the mirror, my facial lines make me look older than I want to look score.

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 Lines (SGA-CFL)Day 30Participants rated the change in their Crow's Feet Lines using the 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 at Day 30. 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 BaselineBaseline, Day 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.
Percentage of Participants Mostly or Very Satisfied With Their Crow's Feet Lines on the Facial Line Satisfaction QuestionnaireDay 30Participants assessed their overall satisfaction at the present moment using a 5-point scale where -2=very dissatisfied, -1=mostly dissatisfied, 0=neither dissatisfied nor satisfied, 1=mostly satisfied and 2=very satisfied. The percentage of participants mostly or very satisfied is reported.
Percentage of Participants With a ≥3-Point Improvement From Baseline for Facial Line Outcomes Questionnaire (FLO-11) Item 8 at Day 30Baseline, Day 30The FLO-11 questionnaire is comprised of 11 items that assess the subject's perceptions about specific aspects of their facial lines for the previous 7 days.
