Primary Outcome Measures
NameTimeMethod
Efficacy, Measured as the Percentage of Participants Who Responded to Treatment1 Month from baseline

Response defined as ≥ 1 point improvement from baseline (prior to treatment) on the Facial Wrinkle Scale at maximum frown as rated by an independent masked panel of physicians specifically qualified to assess study photographs using subject photographs at 1 month from treatment.

Secondary Outcome Measures
NameTimeMethod
Response at Maximum Frown Rated by Independent Rater4 months from baseline

Response defined as ≥ 1 point improvement from baseline on the Facial Wrinkle Scale (0=None to 3=severe) at maximum frown as rated by an independent masked panel of physicians specifically qualified to assess study photographs using subject photographs at 4 months from baseline.

Response at Maximum Frown Rated by Treating Physician4 months from baseline

Response defined as ≥ 1 point improvement from baseline on the Facial Wrinkle Scale (0=None to 3=severe) at maximum frown as rated by the treating physicians using subject photographs at 4 months from treatment.

Subject Satisfaction4 months from baseline

Assessment of subject treatment satisfaction by subject questionnaire and diary at 4 months from treatment. Extremely satisfied, satisfied, and slightly satisfied were categorized as "Satisfaction" and extremely dissatisfied, dissatisfied, and slightly dissatisfied were categorized as "Dissatisfaction." Subjects with missing data were categorized as "Missing."

Subject Perception of Treatment OnsetOpen-ended time frame for the 4 month study duration. Data for onset and peak effect is recorded in the subject diary.

Assessment of subject perception of date of treatment onset using a take-home diary
