Mean Change From Baseline in Wrinkle Severity Rating Scale (WSRS) at Week 24 After Final Initial Injection |
WSRS is a validated 5-point reference scale with photographs that classifies deep facial wrinkles (nasolabial folds). WSRS represents clinically meaningful change in NLF severity from the adjacent grades where 1= absent (no visible fold; continuous skin line), 2 = mild (shallow but visible fold with a slight indentation; minor facial feature; implant expected to produce a slight improvement in appearance), 3 = excellent (correction is expected from injectable implant), 4 = severe (very long and deep folds; prominent facial feature; less than 2 mm visible fold when stretched; significant improvement expected from injectable implant), 5 = extreme (extremely deep and long folds, detrimental to facial appearance; 2 to 4 millimeter (mm) visible V-shaped fold when stretched; unlikely to have satisfactory correction with injectable implant alone). A negative change from baseline indicates improvement. |

Mean Change From Baseline in Wrinkle Severity Rating Score (WSRS) at Week 3 After Final Initial Injection |
WSRS is a validated 5-point reference scale with photographs that classifies deep facial wrinkles (nasolabial folds). WSRS represents a clinically meaningful change in nasolabial fold severity from the adjacent grades where 1 = absent (no visible fold; continuous skin line), 2 = mild (shallow but visible fold with a slight indentation; minor facial feature; implant is expected to produce a slight improvement in appearance), 3 = excellent (correction is expected from injectable implant), 4 = severe (very long and deep folds; prominent facial feature; less than 2 mm visible fold when stretched; significant improvement is expected from injectable implant), 5 = extreme (extremely deep and long folds, detrimental to facial appearance; 2 to 4 mm visible V-shaped fold when stretched; unlikely to have satisfactory correction with injectable implant alone). A negative change from baseline indicates improvement. |

Mean Change From Baseline in Wrinkle Severity Rating Score (WSRS) at Week 12 After Final Initial Injection |
WSRS is a validated 5-point reference scale with photographs that classifies deep facial wrinkles (nasolabial folds).

Mean Change From Baseline in Wrinkle Severity Rating Score (WSRS) at Week 36 After Final Initial Injection |
WSRS is a validated 5-point reference scale with photographs that classifies deep facial wrinkles (nasolabial folds).

Mean Change From Baseline in Wrinkle Severity Rating Score (WSRS) at Week 48 After Final Initial Injection |
WSRS is a nasolabial fold severity from the adjacent grades where 1 = absent (no visible fold; continuous skin line), 2 = mild (shallow but visible fold with a slight indentation; minor facial feature; implant is expected to produce a slight improvement in appearance), 3 = excellent (correction is expected from injectable implant), 4 = severe (very long and deep folds; prominent facial feature; less than 2 mm visible fold when stretched; significant improvement is expected from injectable implant), 5 = extreme (extremely deep and long folds, detrimental to facial appearance; 2 to 4 mm visible V-shaped fold when stretched; unlikely to have satisfactory correction with injectable implant alone). A negative change from baseline indicates improvement. |

Mean Change From Baseline in Participant Self-Assessment of Wrinkle Severity at Week 24 After Final Initial Injection |
Participants self-assessment was measured by using a wrinkle severity scale with 1 being absent and 5 being extreme. Each participant was to perform an assessment of the wrinkle severity based on self-assessment score: 1= Absent (No visible fold; continuous skin line), 2= Mild (Shallow but visible fold with a slight indentation), 3= Moderate (Moderately deep folds), 4= Severe (Very long and deep fold), 5= Extreme (Extremely deep and long folds). A negative change from baseline indicates improvement. |

Participant Pain Assessment After the Initial Injection |
Participant pain severity for each NLF was assessed at time 0, 15, 30, 45, 60 minutes and 24 hours after the initial injection using an 11-point Numeric Pain Intensity Scale (NPIS).The NPIS was a pain screening tool, commonly used to assess pain severity at that moment in time using a 0-10 scale, with 0 is no pain and 10 is the worst possible pain where a lower score correlates to better outcome for pain. |

Participant Pain Assessment After the Initial Touch-up Injection |
Participant pain severity for each NLF was assessed at time 0, 15, 30, 45, 60 minutes and 24 hours after the initial injection using NPIS. The NPIS was a pain screening tool, commonly used to assess pain severity at that moment in time using a 0-10 scale, with 0 is no pain and 10 is the worst possible pain where a lower score correlates to better outcome for pain. |
At 0, 15, 30, 45, 60 minutes and 24 hours after the Initial Touch-up Injection (At 3 weeks after initial injection) |

Number of Participants With Adverse Event (AEs) |
AE was defined as any untoward medical occurrence in a participant, which does not necessarily have a causal relationship with the study drug. Number of participants with AEs were reported. Event was unrelated to study product or injection procedure. If the treated side where an AE occurred was not applicable, this AE was summarized under each treatment group." |
From start of study drug administration up to 62 weeks |
