Science
Mechanism of Action
This peptide operates through a multi-pronged approach, primarily by reinforcing the skin barrier and optimizing moisture levels. It significantly promotes the synthesis of matrix proteins, collagen, elastin, hyaluronic acid, glycosaminoglycans, and fibronectin, which are essential for maintaining skin firmness and elasticity. By activating fibroblasts and regulating water metabolism, Palmitoyl Dipeptide-18 supports overall skin vitality and health. Additionally, it contributes to a soothing and repairing effect by reducing inflammation and facilitating the repair of damaged skin, and is believed to reduce the release of catecholamines to relax facial muscles, thereby minimizing expression lines.

The Formula
Formulation
Stability
Palmitoyl Dipeptide-18 should be stored in a cool, dry environment, ideally between 2-8°C, and protected from light. For long-term preservation, temperatures of -20°C to -15°C are recommended, maintaining an airtight package when not in use. The palmitoylation of the peptide significantly improves its inherent stability and enhances skin permeability due to increased lipophilicity.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) currently has Palmitoyl Dipeptide-18 under 'monograph development in progress,' indicating that a definitive safety assessment and maximum concentration for cosmetic use are not yet established. However, acute oral toxicity studies in rats have shown commercialized products containing 0.01% (100 ppm) of this ingredient to be non-toxic. Supplier information further assures that the ingredient is free from heavy metals and is non-irritating to both skin and eyes.

Verdict
Palmitoyl Dipeptide-18 exhibits promising multi-functional benefits for addressing skin aging and repair; however, its full clinical efficacy and long-term safety profile await comprehensive regulatory assessment by the CIR.
