Compatibility of Copper Peptide GHK-Cu, Galactomyces Ferment Filtrate, and Tranexamic Acid in Hyaluronic Gel

Yes, Copper Peptide GHK-Cu, Galactomyces Ferment Filtrate (Pitera), and Tranexamic Acid can be combined in a Double Hyaluronic Gel base.

The primary consideration when mixing these ingredients is their optimal working pH range. Based on the product information:

• Copper Peptide GHK-Cu is most stable and effective in a pH range of 4.5-7.4.
• Galactomyces Ferment Filtrate has a natural pH typically between 4-7 and is stable within this range.
• Tranexamic Acid is effective in a broader pH range of 3-8, with optimal efficacy often cited between 4.0-7.0.

Since the optimal pH ranges for these ingredients overlap significantly (specifically within the 4.5 to 7.0 range), they can be successfully formulated together. A Double Hyaluronic Gel is a suitable base as it is water-based and the pH can be adjusted to fall within this compatible range (e.g., pH 5.0-6.5) to ensure the stability and efficacy of all three active ingredients.

Always ensure the final formulation's pH is checked and adjusted to the appropriate range after all ingredients are added.
