Science
Mechanism of Action
This lipo-peptide functions as an α-MSH (α-Melanocyte-stimulating hormone) antagonist, selectively binding to MC1R receptors on the melanocyte surface. This action interrupts the hormonal signaling pathway responsible for increased melanin production. Its palmitoyl group enhances skin penetration to reach melanocytes. In cutting-edge 'drone' encapsulation systems, it acts as a surface ligand, guiding the encapsulate directly to MC1R. Upon successful binding and cellular uptake, a secondary peptide, Palmitoyl sh-Octapeptide-24 Amide, is released internally to inhibit tyrosinase gene expression, thereby comprehensively restricting melanin synthesis.

Key findings
- 01 Within a 'Cell-targeted “Drone” Encapsulate' technology, this ingredient significantly improved skin dyspigmentation, including lightening and overall evenness. Progressive enhancement was noted from week 2 through week 16 in a test product utilizing this system.
- 02 At minimal concentrations, it is employed as a targeting peptide in advanced complexes (e.g., X50® Pure White, X50® Lightening) to precisely deliver other active ingredients to melanocytes, thereby amplifying their effectiveness in skin brightening and contributing to a more even complexion.

Stability
The raw material exhibits stability; however, optimal long-term storage for ingredient integrity is recommended at -20°C.
Synergies
- Enhances the targeted delivery and efficacy of co-formulated active ingredients by specifically guiding them to melanocytes, especially within advanced 'drone' encapsulation technologies.
Conflicts
- Not recommended for co-formulation with formaldehyde-releasing preservatives, based on data for related peptides.
- Requires careful compatibility assessment within existing emulsion systems to prevent potential aggregation in either water or oil-based carriers.
Safety
Safety Profile
A specific safety assessment by the Cosmetic Ingredient Review (CIR) or Scientific Committee on Consumer Safety (SCCS) for this exact complex ingredient was not found in the available research. While related palmitoyl peptides have been reviewed, this compound lacks a dedicated status from these bodies.
