This clinical trial is a double-blind, randomized, within-subject controlled, 2-armed, single-center study sponsored by SciVision Biotech Inc. and approved by National Taiwan University Hospital Research Ethics Committee. The aim of this post-marketing study is to evaluate the safety and efficacy of Hya-Dermis mixed with lidocaine, as well as the effectiveness of corrections of Hya-Dermis mixed with lidocaine. Accounting for potential loss to follow-up, the minimum enrollment was statistically determined to be 40 patients. The study was estimated to be held one and half year including a 0-2 weeks screening period, a day of treatment, and follow-up at month 1, 3, 6, 9, 12. Patient informed consent forms will be obtained before the treatment. A pre-treatment photograph, nasolabial folds (NLF) severity scale scores, and individual aesthetic satisfaction will be the baseline. Two sets of randomized numbers are used, patient numbers and treatment numbers. Participants with odd patient numbers will be assigned to nasolabial group and those with even patient numbers will be assigned to nasolabial\&cheekbone group. Participants receive experiment treatment (Hya-Dermis mixed with lidocaine) in one side and control treatment (Hya-Dermis mixed with normal saline) in the other side of the face randomly depending on the treatment numbers. Both physicians and participants are only blind to the treatment assignment. 30 minutes after the injection, a post-photograph will be used to evaluate NLF severity scale scores and global aesthetic improvement scale (GAIS) by physicians. A questionnaire including the Visual Analog Scale (VAS) of pain during the treatment and individual aesthetic satisfaction will be collected from patients. The effectiveness analyses compare NLF severity scale scores and GAIS based on photograph records from physicians, as well as participant questionnaires for each group on every visit. The safety assessment evaluates any recorded adverse events following the device treatment.

Pain Visual Analog Scale
A quantification of the severity of pain experienced by individuals during the treatments. A scale of 100 mm horizontal line will be labeled by participants to assess pain on both sides of the injected areas 30 minutes after the treatment. The one on the extreme left (0) represents painless while the one on the extreme right (100) is set as the most pain could be imagined by participants.
Time frame: 30 miuntes post-treatment
Adverse events report
Any adverse events and abnormal physical parameters or reports occurred and disappeared should be monitored throughout the trial. The records should be assessed and keep on track of the severity of individual adverse events and correlation with the treatment. Severity assessment: To assess the level of severity by rating 0 (none), 1 (mild), 2 (median), and 3 (sever). Correlation assessment: Physicians evaluate the impact of adverse events for each individual and determine their causality of the treatment. Based on the correlation with the treatment, giving score 0 (no correlated), 1 (low correlated), 2 (suspected correlated), 3 (most likely correlated). Adverse events tracking: Any adverse events should be reported to the physicians by participants. Physicians keep following up adverse events experienced participants until the event disappeared or the symptoms stabilized.
Time frame: From date of treatment to 12 months
Nasolabial folds (NLF) severity scale
Based on Skin Aging Atlas: Volume 2, Asian type photographs13, taking gender and NLF into consideration to quantify the degree of NLF severity. A validated 8-point photographic scale scored the severity grade from 0 (absent) to 7 (extreme) will be used to assess the severity of NLF at baseline, 30 minutes post-treatment, and every follow-up at 1, 3, 6, 9, 12 months.
Time frame: From the baseline, 30 minutes post-treatment, to every follow-up at 1, 3, 6, 9, 12 months
Global aesthetic improvement scale (GAIS)
To quantify the level of overall aesthetic improvement 30 minutes after treatments and every follow-up at 1, 3, 6, 9, 12 months. A scale from 1 to 5 represent worse (1), no change (2), improved (3), much improved (4), and very much improved (5).
Time frame: 30 minutes post-treatments and follow-ups at 1, 3, 6, 9, 12 months
Aesthetic satisfaction questionnaire
Subjects subjectively assessed overall satisfaction of general appearance toward the effectiveness of the treatment by rating 1 (not at all satisfied), 2 (not satisfied), 3 (neither satisfied nor dissatisfied), 4 (somewhat satisfied), and 5 (highly satisfied).
Time frame: From the baseline, 30 minutes post-treatment, to every follow-up at 1, 3, 6, 9, 12 months
