What Is Myristoyl Nonapeptide-3?
Myristoyl nonapeptide-3, known by the trade name SpecPed® MN3P, is a synthetic peptide designed to have anti-aging benefits. It is also marketed by Symrise under the trade name RetinoPeptide 189. At the time of this writing, there is little independent research regarding its efficacy.
The manufacturer of this peptide claims it works by mimicking retinoic acid to encourage cell turnover and collagen synthesis. We will update this definition if/when more third-party studies are published.
Supplier-recommended use levels of myristoyl nonapeptide-3 range from 0.005% and 0.05%.
