Secondary
| Measure | Time frame | Description |
|---|---|---|
| Investigator-rated improvement rate of glabellar lines at maximum frown | Week 8, 12, 16 | The investigator and participant evaluate the participant's GL severity using a 4-grade scale (0 to 3) where 0=none and 3 = severe. |
| Investigator-rated improvement rate of glabellar lines at rest | Week 4, 8, 12, 16 | The investigator and participant evaluate the participant's GL severity using a 4-grade scale (0 to 3) where 0=none and 3 = severe. |
| Participant-rated improvement rate of glabellar lines at maximum frown | Week 4, 8, 12, 16 | The investigator and participant evaluate the participant's GL severity using a 4-grade scale (0 to 3) where 0=none and 3 = severe. |
| Participant-rated improvement rate of glabellar lines at rest | Week 4, 8, 12, 16 | The investigator and participant evaluate the participant's GL severity using a 4-grade scale (0 to 3) where 0=none and 3 = severe. |
