About this ingredient
Myristoyl nonapeptide-3 (INCI Myristoyl Nonapeptide-3) is a synthetic nine-amino-acid peptide linked to a fatty acid, the myristoyl chain that improves its affinity with skin. It enters a formula as an active aimed at anti-aging care and the look of skin tone. On efficacy, the supplier ties it to more even tone and greater firmness, but independent data are sparse. It is reasonable to see it as a supporting component within the anti-aging category and not to expect a visible change from it alone, only as part of a complete formula. Applied topically it has no systemic relevance, so it can be used during pregnancy and breastfeeding. Tolerance is good, with low irritation and allergy potential, suitable for sensitive skin. Already-sensitized people may see an occasional reaction, though most do not.
