The purpose of this study is to evaluate the efficacy and safety of PavéDerm J-fill soft dermal filler vs. Restylane® Lyft lidocaine in the treatment of moderate to severe nasolabial folds.
This is a single-center, subject and evaluator blinded, intra-individual, split-face controlled clinical trial. After subjects voluntarily give written consent to the participation in the study, his/her eligibility for the study will be judged through demographic and past \& medication history investigation and laboratory test. Subjects eligible in the screening will be enrolled. Each patient will receive PavéDerm J-Fill Soft Dermal Filler in one nasolabial fold and Restylane Lyft Lidocaine (20 mg/mL Hyaluronic acid with 3 mg/ml Lidocaine hydrochloride) in the other by randomization. The faces of all subjects are going to be digitally photographed at rest upon every visit. The identical ambient conditions will be used for all photographs and assessments. To ensure blinding status, the subjects will be put on eye mask during injection. On injection day, subjects will receive injections, with at least 60 minute apart, to each nasolabial fold by the treating investigator. The amount of injection will be determined according to the width, length, and depth of the nasolabial folds to ensure optimal correction for each subject. The injected volume will not exceed 1.0 mL in ipsilateral nasolabial fold. The relevant information associated with the injection of the investigational medical device will be documented. After each injection, the treating investigator will observe subjects through 30 minutes for assessment of adverse events. Subjects will be asked about adverse events at each follow-up visit, and any adverse events will be documented for safety assessment. Clinical efficacy will be assessed by the appropriately trained evaluator using the WSRS and GAIS under blinded fashion, as well as by subjects using GAIS. Pre-treatment photographs of each subject taken at the pre-treatment (baseline) will be reviewed and will be used for comparison. The blinded evaluator will assess the photographs taken at each visit after the study device administration (photographic assessment). All subjects will perform the self-assessment by comparing their appearance in a mirror against a high-magnification photograph taken at baseline at each visit after the study device administration. The mirror symmetry will be reminded in all subjects. Under the explanation by the treating investigator or designee, subjects will assess the satisfaction of wrinkle improvement using the GAIS scoring. Pain is going to be assessed using a patient self-assessment 10-cm visual analogue scale with anchors at 0 m (no pain) and 10 cm (extreme pain).

The Mean change of the Wrinkle Severity Rating Scale scored by the blinded evaluator.
Mean change of the Wrinkle Severity Rating Scale (WSRS) from baseline to Week 24 will be assessed by a blinded evaluator who will judge the severity score from taken photos based on the definition of WSRS Grades.
Time frame: From baseline to Week 24.
The Mean change of the Wrinkle Severity Rating Scale assessed by the blinded evaluator.
Mean change of the Wrinkle Severity Rating Scale (WSRS) from baseline to Week 4 and Week 12 will be assessed by a blinded evaluator who will judge the severity score from taken photos based on the definition of WSRS Grades.
Time frame: From baseline to Week 4 and 12.
Injection pain evaluated by the subjects after injection
Visual Analogue Scale for injection site pain assessment will be evaluated by the subject with anchors at 0 cm (no pain) and 10 cm (extreme pain) after the injection.
Time frame: 0, and 15, 30, 45, and 60 minutes after the injection.
The Global Aesthetic Improvement Scale assessed by the blinded evaluator and subjects
1. Proportion of subjects with a ≥ 1 point on Global Aesthetic Improvement Scale (GAIS) from baseline to Week 4, 12, and 24 after injection will be evaluated by a blinded evaluator who will judge the severity score from taken photos based on the definition of GAIS Grades. 2. Proportion of subjects with a ≥ 1 point on GAIS from baseline to Week 4, 12, and 24 after injection will be evaluated by the subjects based on a live assessment.
Time frame: At Week 4, 12, and 24
