Science
Mechanism of Action
This synthetic lipopeptide, also recognized as Palmitoyl Glycylproline, primarily functions by activating Prolidase, an enzyme critical for regulating collagen regeneration, thereby promoting collagen bioproduction. Its multifaceted action extends to exhibiting anti-inflammatory properties, inhibiting collagenase to prevent collagen degradation, and accelerating the skin's natural wound healing processes. It further supports dermal health by enhancing the growth of human skin fibroblasts, increasing the synthesis of extracellular matrix proteins, and facilitating keratin function essential for skin regeneration and barrier resilience, while also contributing to balanced skin hydration.

Stability
Palmitoyl Dipeptide-17 is water-soluble and, when dissolved in water, presents an acidic pH of 3.6. Its secondary structure composition demonstrates robust stability across a wide pH range, specifically from pH 4 to pH 10, when maintained at a temperature of 37 °C.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel is actively developing a specific monograph for Palmitoyl Dipeptide-17, indicating ongoing safety assessment. Historically, related 'Palmitoyl Oligopeptides' were grouped, but the Panel has since prioritized evaluation based on distinct amino acid sequences. No specific FDA or SCCS regulatory status for this peptide has been identified, though peptides are generally considered biocompatible due to their natural presence in the body.
