Measure Description |
Time Frame |
|---|---|---|
|
Percentage of Responders Based on Composite Facial Wrinkle Scale Assessment of Crow's Feet Line Severity at Maximum Smile
Time Frame: Baseline, Day 30
|
The composite facial wrinkle scale assessment is based on both the Investigator and Subject Facial Wrinkle scales at Day 30.
The Investigator assessed the severity of the patient's Crow's Feet Lines at maximum smile using the 4-point Facial Wrinkle Scale: 0=none, 1=mild, 2=moderate or 3=severe and the patient assessed the severity of their Crow's Feet Lines at maximum smile using the same 4-point Facial Wrinkle Scale.
A responder is defined as a participant with a ≥ 2-grade improvement from Baseline.

|
Percentage of Participants Achieving a Grade of None or Mild at Maximum Smile Based on the Investigator's Facial Wrinkle Scale Assessment of the Severity of Crow's Feet Lines
Time Frame: Day 30
|
The Investigator assessed the severity of the patient's Crow's Feet lines at maximum smile using the 4-point Facial Wrinkle Scale: 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.

|
Percentage of Participants With a ≥ 1-Grade Improvement From Baseline by Investigator Facial Wrinkle Scale Assessment of the Severity of Crow's Feet Lines at Maximum Smile
Time Frame: Baseline, Day 30
|
The Investigator assessed the severity of the patient's Crow's Feet Lines at maximum smile using the 4-point Facial Wrinkle Scale: 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 With a ≥ 1-Grade Improvement From Baseline by Investigator Facial Wrinkle Scale Assessment of the Severity of Crow's Feet Lines at Rest
Time Frame: Baseline, Day 30
|
The Investigator assessed the severity of the patient's Crow's Feet Lines at rest using the 4-point Facial Wrinkle Scale: 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.

Subject Global Assessment of Change in Crow's Feet Lines (SGA-CFL) Score
Time Frame: Day 30
|
Patients rated the change in their Crow's Feet Lines using the SGA-CFL 7-point scale: 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.
Lower scores indicate improvement.

Day 30
|
|
Percentage of Participants Who Judged Themselves in a Younger Self-Perception of Age Category Than at Baseline
Time Frame: Baseline, Day 30
|
Participants were considered to judge themselves 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 With a ≥ 2-point Improvement From Baseline for Facial Line Outcomes Questionnaire (FLO-11) Item 2 at Day 30
Time Frame: Baseline, Day 30
|
The percentage of FLO-11 Item #2 responders, defined as participants with a ≥ 2-point improvement in FLO-11 score from Baseline for FLO-11 Question #2: "When I look in the mirror, my facial lines make me look older than I want to look."
The 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 is scored on an 11-point scale (0=not at all, 5=somewhat, 10=very much).

Percentage of Participants With a ≥ 2-point Improvement From Baseline for Facial Line Outcomes Questionnaire (FLO-11) Item 5 at Day 30
Time Frame: Baseline, Day 30
|
The percentage of FLO-11 Item #5 responders, defined as participants with a ≥ 2-point improvement in FLO-11 score from Baseline for FLO-11 Question #5: "My facial lines make me look less attractive than I want to look."
The 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 is scored on an 11-point scale (0=not at all, 5=somewhat, 10=very much).

|
Percentage of Participants With a ≥ 3-point Improvement From Baseline for Facial Line Outcomes Questionnaire (FLO-11) Item 8 at Day 30
Time Frame: Baseline, Day 30
|
The percentage of FLO-11 Item #8 responders, defined as participants with a ≥ 3-point improvement in FLO-11 score from baseline for FLO-11 Question #8: "My facial lines make me look tired" The 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 is scored on an 11-point scale (0=not at all, 5=somewhat, 10=very much).
