Using Copper Peptide with Silky Serum Base

Yes, you can definitely use Copper Peptide (GHK-Cu, Copper Tripeptide-1) with Silky Serum Base (Face/Eye) to create a serum.

Here's how to incorporate it and some important considerations:

• Mixing: Add the Copper Peptide solution in the final step of your formulation, ensuring the temperature is below 40°C.
• Usage Rate: The recommended usage rate for Copper Peptide (1000ppm solution) is typically 1-3% of the total formula.
• pH Stability: Copper Peptide is most stable in a pH range of 4.5-7.4. Ensure your final serum pH falls within this range for optimal effectiveness.
• Serum Texture: When using Silky Serum Base, you can achieve a light, soft, and quickly absorbing serum texture by mixing it with water and water-soluble ingredients. The ratio of water to base will determine the final viscosity.
• Preservation: If you are adding water to the Silky Serum Base, you must include a suitable preservative in your formula to prevent microbial growth.
• Stability Tip: The Silky Serum Base description mentions that adding 1% NaCl (pure salt) or Magnesium Sulfate can help increase the stability of the formula and prevent separation. Consider adding one of these in the final step.

By following these guidelines, you can successfully create a serum combining the benefits of Copper Peptide with the pleasant texture of the Silky Serum Base.
