Science
Mechanism of Action
This lipophilic peptide acts as a biomimetic signaling molecule, primarily by inhibiting the NF-κB pathway, which reduces erythema and sensitive reactions. It bolsters the skin barrier through the promotion of tight junction protein synthesis and enhances skin appearance, firmness, elasticity, and thickness by increasing keratinocyte proliferation. Myristoyl Tetrapeptide-12 also influences matrix metabolism by activating SMAD2 and inducing SMAD3-DNA linkage, while controlling vasodilation, soothing inflammation, and improving angiogenesis within skin tissue. Collectively, it signals the body to activate endogenous skin repair mechanisms, fostering regeneration and strengthening skin structure.

Stability
Myristoyl Tetrapeptide-12 maintains stability for 24 months from manufacture when stored in a freezer at -20℃ to -15℃, protected from light, and airproofed. As a lyophilized powder, it is stable for 6 months at -20°C to -80°C. Aliquoting is recommended for multiple uses to prevent degradation from repeated freeze-thaw cycles.

Verdict
While Myristoyl Tetrapeptide-12 demonstrates promising mechanistic actions for skin health and confirmed efficacy in stimulating hair and eyelash growth, current clinical studies lack isolated data to definitively ascertain its specific anti-aging efficacy on the skin.
