Primary Outcome Measures:

Percentage of Participants Achieving a Score of None or Mild by Investigator-Assessed Facial Wrinkle Scale With Photonumeric Guide (FWS) in Forehead Lines at Maximum Eyebrow Elevation [ Time Frame: Day 30 ] [ Designated as safety issue: No ]
The Investigator assessed the severity of the patient's forehead lines at maximum eyebrow elevation using the 4-point FWS: 0=none, 1=mild, 2=moderate or 3=severe. The percentage of participants with a score of none or mild at Day 30.
Percentage of Participants Achieving a Score of None or Mild by Subject-Assessed Facial Wrinkle Scale With Photonumeric Guide (FWS) in Forehead Lines at Maximum Eyebrow Elevation [ Time Frame: Day 30 ] [ Designated as safety issue: No ]
The patient assessed the severity of their forehead lines at maximum eyebrow elevation using the 4-point FWS: 0=none, 1=mild, 2=moderate or 3=severe. The percentage of participants with a score of none or mild at Day 30.

Secondary Outcome Measures:

Percentage of Participants Achieving Satisfied or Very Satisfied by Subject Assessment of Satisfaction of Appearance of Forehead Lines [ Time Frame: Day 30 ] [ Designated as safety issue: No ]
Participants rated their overall satisfaction with the appearance of the forehead line area using a 5-point scale: 1=very unsatisfied, 2=unsatisfied, 3=neutral, 4=satisfied or 5=very satisfied. The percentage of participants with a rating of satisfied or very satisfied at Day 30.
Percentage of Participants With a ≥1 Grade Improvement From Baseline by Investigator-Assessed FWS in Forehead Lines at Rest [ Time Frame: Baseline, Day 30 ] [ Designated as safety issue: No ]
The Investigator assessed the severity of the patient's forehead lines at rest using the 4-point FWS: 0=none, 1=mild, 2=moderate or 3=severe. The percentage of participants with a ≥1 grade improvement from baseline.
Percentage of Participants With a ≥1 Grade Improvement From Baseline by Subject-Assessed FWS in Forehead Lines at Rest [ Time Frame: Baseline, Day 30 ] [ Designated as safety issue: No ]
Participants assessed the severity of their forehead lines at rest using the 4-point FWS: 0=none, 1=mild, 2=moderate or 3=severe. The percentage of participants with a ≥1 grade improvement from baseline.
