Details and patient eligibility

About

The study is to verify that Dermalax (Deep) is not inferior to the reference device, Restylane®, in terms of efficacy and safety in the correction of nasolabial folds. 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 subject diary and follow up visits.

Enrollment: 66 patients

3. Subjects with a liver problem and/or blood coagulation defect or subjects who require the administration of an antithrombotic agent during the clinical trial period (with the exception of low dose Aspirin 100 mg, maximum of 300 mg/day).
4. Subjects who have used a local ointment on their faces (medication such as steroid or retinoid are included and cosmetic products are excluded from this criterion) within 4 weeks prior to screening or subjects who are planning on using such an ointment during the clinical trial period.
5. Subjects who have received treatment for wrinkles or acne within 24 weeks prior to screening.
6. Subjects who have received facial (chemical) peels and/or skin rejuvenation procedures or plastic surgeries, including the injection of the Botulinum toxin, within 24 weeks prior to screening.
