Brief summary: This clinical study is a confirmatory clinical study to prove that the test device, DLMR01, is non-inferior to the control device, Rejuran®, in terms of temporary wrinkle improvement effect on crow's feet and safety. After applying DLMR01, a test device, and Rejuran®, a control device, respectively to wrinkles around the eyes, randomization to compare and evaluate the temporary wrinkle improvement effect and safety of the two clinical study medical devices, subject-evaluator blinding, pair matching, It was designed as a comparative clinical study.

Detailed description: A total of 218 clinical study subjects participated in this clinical study, and the clinical study subjects signed a written informed consent for this clinical study at the screening visit (visit 1), and only if they satisfied various test results and selection/exclusion criteria. Randomly prescribed and applied medical devices for clinical studys (test devices, control devices). A total of 5 visits were scheduled for the subject and visit 1 (screening visit) was conducted within 14 days prior to the first application of the subjects clinical study medical device. Subjects visited the clinical study institution at 2 weeks (visit 3), 4 weeks (visit 4), and 12 weeks (visit 5) after the final application of clinical study medical devices (visit 2) and conducted observation and examination to conduct clinical study. The efficacy and safety of the test medical device were confirmed.

Eligibility criteria: Inclusion Criteria:

1. Adults over 19 years of age
2. Subjects who voluntarily decided to participate in this clinical trial and provided written consent on the subject's informed consent form were included.
3. Subjects who desired improvement in bilateral crow's feet wrinkles and had a Crow's Feet Grading Scale score of 2 or higher during both rest and maximum smiling were included. It was also required that the crow's feet wrinkles were visually symmetrical on both sides.
4. Subjects who agreed not to undergo any procedures or treatments during the course of the clinical trial that could potentially affect the improvement of periorbital wrinkles, other than the interventions specified in the trial, were included.
5. Subjects who were capable of understanding and following instructions and were available to participate throughout the entire pre-trial period were included.

4. Subjects who had undergone invasive laser procedures, deep chemical peels, or any other procedures or surgeries related to wrinkle improvement on their face within 6 months prior to the screening date were excluded.
5. Subjects who had received wrinkle improvement treatments within 6 months prior to the screening date, such as collagen or hyaluronic acid fillers, polyalkylimide fillers, or any other treatments involving the use of injectable substances, were excluded.
6. Subjects who had received wrinkle improvement treatments using calcium hydroxylapatite (CaHA) fillers within 12 months prior to the screening date were excluded.
7. Subjects who had inserted permanent dermal fillers such as softform or silicone for facial augmentation in the facial area were excluded.
8. Subjects who had facial scars that had not been treated for more than 12 months or had scars or marks in the areas where the investigational medical device would be applied were excluded.
