CONDUCTED EFFICACY EVALUATION STUDY OF NMN THIRTYNE SERUM.
Thank you for your continued patronage of NMN Sirtuin brand products.
We have conducted an evaluation test of our product "NMN Sirteen Serum" based on the "Cosmetic Functional Evaluation Guidelines" at a professional third-party institution, and found a reduction in wrinkle grade in the used area compared to the unused area of the product after 4 weeks of use.
It has also been confirmed safe on the skin through a third-party patch test.
We look forward to your continued patronage of our brand products.
