COPPER TRIPEPTIDE-1 PALMITAMIDE.

Key findings

1. 01 Studies on the parent compound, Copper Tripeptide-1 (GHK-Cu), consistently demonstrate its ability to stimulate collagen synthesis, resulting in measurable improvements in skin elasticity, density, and firmness.
2. 02 Significant reductions in the appearance of fine lines and wrinkles, alongside improvements in skin clarity and a reduction in hyperpigmentation, have been observed with GHK-Cu application.
3. 03 GHK-Cu has shown effectiveness in accelerating wound healing and reducing inflammation, with some comparative research suggesting superior performance to retinoids or vitamin C without inducing irritation.
4. 04 Other peptides modified with palmitic acid, such such as Palmitoyl Tripeptide, have clinically demonstrated measurable wrinkle reduction within an eight-week period, supporting the enhanced efficacy of palmitamide modifications.

Stability

To preserve the ingredient's optimal bioactivity and ensure complex stability, it must be incorporated into formulations during the cold-process phase, maintaining temperatures strictly below 40 °C. A neutral to slightly acidic pH range of 5.0–7.0 is critical to prevent premature dissociation of the copper ions. The integrated palmitic acid modification inherently boosts its lipophilicity and intrinsic stability within a formulation.

Conflicts

• Strong acids (e.g., lactic acid, salicylic acid, fruit acids, mandelic acid): Can form complexes with copper ions, leading to inactivation and undesirable color changes.
• Retinoids (VA alcohols and derivatives): May result in turbidity, viscous green discoloration, and inactivation of copper ions due to their acidic nature.
• Vitamin C and its derivatives (VC derivatives): Induce a redox reaction that renders both ingredients ineffective.
• Copper-chelating agents (e.g., carnosine, EDTA): Can bind copper ions, significantly reducing the peptide's efficacy and potentially causing discoloration (e.g., purple with carnosine).
