Science
Mechanism of Action
Operating as a targeted signaling peptide, Dipeptide-7 primarily engages with fibroblasts to instigate beneficial cellular responses. It effectively stimulates the production of vital collagen, leading to a noticeable reduction in fine lines and a significant improvement in overall skin texture, resulting in a firmer, more vibrant complexion. Beyond collagen, it also promotes the synthesis of other critical extracellular matrix components, including elastin, hyaluronic acid, glycosaminoglycans, and fibronectin. Furthermore, this ingredient enhances the skin's natural barrier function, aids in maintaining optimal hydration levels, and exhibits antioxidant capabilities, supporting comprehensive skin regeneration and defense against environmental aggressors.

Stability
As a lipopeptide conjugated with palmitic acid, Dipeptide-7 exhibits improved skin penetration and stability, and is noted for its oil solubility. For optimal preservation, it should be stored in dry, dark conditions at low temperatures, ideally between 0-4°C for short durations and -20°C for long-term storage, to mitigate degradation. While no precise optimal pH range is specified, peptide stability is generally pH-dependent; buffer systems within pH 3-5 can help reduce deamidation and oxidation, and a physiological pH of 7.0-7.4 is frequently suitable depending on amino acid composition. It is advisable to integrate this peptide with other compatible skincare ingredients following manufacturer's guidelines for best performance.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Palmitoyl Dipeptide-7 as safe for use in cosmetic applications. It carries a low concern rating from EWG for potential issues such as cancer, allergies, immunotoxicity, and developmental or reproductive toxicity. Regulatory bodies including the European Union (SCCS) concur on its safety, with no reported widespread adverse effects, allergic reactions, or increased skin sensitivity. There are no specific restrictions or bans from the FDA, indicating general permissibility for cosmetic incorporation.
