结局指标
主要结局
Composite Achievement of Grade 1 or Grade 2 and at Least a 2-Grade Improvement From Baseline Based on Both the Investigator's Assessment and Participant's Self-Assessment Using the Merz Aesthetics Platysma Scale - Dynamic (MAPS-D) At Week 2 of MP
时间窗: At Week 2 of MP
MAPS-D is a validated five-point scale that will be used to grade the platysma prominence. Scores range from Grade 1 (none to minimal) to Grade 5 (very severe). A lower score indicates improvement.

- Achievement of Grade 1 (None to Minimal) or Grade 2 (Mild) And at Least a 2-Grade Improvement From Baseline Based on Participant's Self-Assessment Using MAPS-D at Week 1 and Week 4 up to Week 17 of MP(At Week 1 and Week 4 up to Week 17 of MP)
- Achievement of at Least a +1 (Improved) Score on the Global Aesthetic Improvement Scale (GAIS)-Platysmal Bands Based on the Investigator's Assessment at Week 2 of MP(At Week 2 of MP)
- Achievement of Grade 1 (None to Minimal) or Grade 2 (Mild) And at Least a 2-Grade Improvement From Baseline Based on the Investigator's Assessment Using MAPS-D at Week 2 of MP(At Week 2 of MP)
- Achievement of at Least a +1 (Improved) Score on the GAIS-Platysmal Bands Based on the Participant's Self-Assessment at Week 2 of MP(At Week 2 of MP)
- Achievement of at Least a +1 (Improved) Score Using the GAIS-Lower Face Contour According to the Participant's Self-Assessment at Week 2 of MP(At Week 2 of MP)
- Achievement of Grade 1 (None to Minimal) or Grade 2 (Mild) And at Least a 2-Grade Improvement From Baseline Based on the Participant's Self-Assessment Using MAPS-D at Week 2 of MP(At Week 2 of MP)
- Achievement of at Least a +1 (Improved) Score Using the GAIS-Lower Face Contour According to the Investigator's Assessment at Week 2 of MP(At Week 2 of MP)
- Achievement of at Least a +1 (Somewhat Satisfied) Score Using the Participant's Satisfaction Questionnaire at Week 2 of MP(At Week 2 of MP)
- Achievement of Grade 1 (None to Minimal) or Grade 2 (Mild) And at Least a 2-Grade Improvement From Baseline Based on Both the Investigator's Assessment and Participant's Self-Assessment Using MAPS-D at Week 1 and Week 4 up to Week 17 of MP(At Week 1 and Week 4 up to Week 17 of MP)
