Hello, I'd like to learn more information. The inventor
Tetrapeptide-21 was tested. compare with
Matrixyl 3000 reported that
Tetrapeptide-21 outperformed. The experiment was conducted by the author
Tetrapeptide-21 Not run by independent testers. therefore it may be possible To bias, from the team's point of view, I think there is a chance that
Tetrapeptide-21 will perform better. because it was invented after
Matrixyl 3000 originated many years, which refers to various technologies used in research and development.
Tetrapeptide-21 is much higher, but yields superior results. Maybe not in every aspect From considering the cosmetic products that come out in the market every year There is also a selection.
Matrixyl 3000 Although it has been in development for many years.
