简要总结
This study design is a randomized, multi-center, double Masked, matched Pairs, active-controlled clinical trial. Subjects who voluntarily signed the informed consent and are judged to be eligible for this study will be intradermally injected both of study device and comparator device. Subjects will be randomized to receive injection of study device and comparator device on their each nasolabial fold. Efficacy is evaluated based on the change in Wrinkle Severity Rating Scale (WSRS) from baseline. Safety will be assessed based on 24 weeks follow up visits and subject diary which will be given to subjects during the first 2 weeks after the injection. Any uncomfortable things and adverse events will be investigated from subeject diary and follow up visits.
