Science
Mechanism of Action
Myristoyl Hexapeptide-23 is a biomimetic signal peptide, enhanced with a myristoyl fatty acid for superior skin affinity. Upon topical application, it precisely interacts with keratinocyte and fibroblast receptors, fostering intercellular communication pathways. This interaction is believed to modulate extracellular matrix dynamics, influencing key proteins like collagen and fibronectin to uphold skin's structural integrity and enhance firmness. Concurrently, it operates as a cationic antimicrobial peptide, directly targeting Cutibacterium acnes by damaging their cell membranes, resulting in bacterial demise. This dual action supports significant sebum control, mitigates inflammation, and reduces breakouts, while also improving skin elasticity and texture.

Clinical Evidence
Medium confidenceN/A
Key findings
- 01 In vitro and ex vivo analyses have established 0.001% as the Minimum Inhibitory Concentration (MIC) for Hexapeptide-23 against Cutibacterium acnes, demonstrating robust antimicrobial efficacy crucial for acne management.
- 02 For comprehensive skin and hair care benefits including anti-acne, antibacterial properties, sebum control, and collagen stimulation leading to enhanced firmness, cosmetic formulations typically incorporate Hexapeptide-23 at concentrations ranging from 0.5% to 2.0%. It is important to note that this range represents a formulation guideline rather than direct clinical study results at specific efficacy points.

Stability
For powder form, store in a cool, dry place at 2-8°C, protected from light. For long-term storage, keep at -20°C to -15°C in airtight packaging. While specific optimal pH for Myristoyl Hexapeptide-23 is not detailed, general peptide stability in aqueous solutions is often enhanced within a pH range of 3-5 to mitigate deamidation.
Safety
Safety Profile
While generally reported as non-irritating to both skin and eyes, and confirmed free from heavy metals, Myristoyl Hexapeptide-23 may induce allergic reactions in a subset of individuals. A preliminary skin patch test is advised. Formal safety reviews by bodies such as CIR, SCCS, or FDA have not been documented.
