Science
Mechanism of Action
This biomimetic signal peptide is designed to interact specifically with keratinocyte and fibroblast receptors upon topical application, thereby facilitating crucial cell-to-cell communication. It modulates the extracellular matrix by influencing the expression of vital proteins like collagen and fibronectin, which are essential for maintaining skin's structural integrity. Furthermore, it acts as a cationic antimicrobial peptide, directly targeting Cutibacterium acnes (formerly P. acnes) by disrupting bacterial cell membranes, leading to bacterial demise. Beyond its antimicrobial action, it is known to stimulate collagen synthesis, enhance skin firmness, regulate sebum production, soothe irritation, fortify the skin barrier, and deliver anti-inflammatory, anti-wrinkle, and anti-aging benefits.

Clinical Evidence
Medium confidence0.5%
Key findings
- 01 Demonstrated a minimum inhibitory concentration (MIC) of 0.001% against Propionibacterium acnes (now Cutibacterium acnes), indicating significant anti-acne and antibacterial efficacy.
- 02 Recommended for use in cosmetic formulations at concentrations between 0.5% and 2% to achieve anti-acne, collagen-boosting, and skin-firming benefits.
- 03 When included as part of a comprehensive tripeptide/hexapeptide anti-aging regimen, subjects experienced statistically significant improvements in visual facial photoaging, solar elastosis, collagen stimulation, and enhancement of the cornified layers over 12 weeks of use.

Stability
This peptide maintains stability under recommended storage conditions: cool, dry, and protected from light. For enhanced shelf life, refrigeration (2-8°C) is advised after opening, and long-term storage should be at -20°C to -15°C in airtight containers.
Safety
Safety Profile
While Myristoyl Hexapeptide-23 itself has not undergone a specific CIR safety assessment, manufacturers assert it is free from heavy metals and is non-irritating to skin and eyes, suggesting a high safety profile. It is generally considered appropriate for sensitive skin. However, isolated reports suggest a potential for allergic skin reactions in some individuals, thus a patch test is recommended prior to extensive use.
