Formulation Mixing and Storage Guide

Yes, you can mix Hyaluronic Acid gel base with Matrixyl 3000, Argireline, and Alpha Arbutin at the quantities you have. The concentrations of the active ingredients in the final mixture will be within the recommended usage rates.

Mixing Instructions

1. Start with your Hyaluronic Acid gel base (100g).
2. Weigh out Matrixyl 3000 (5g), Argireline (5g), and Alpha Arbutin (2g).
3. Add the active ingredients (Matrixyl 3000, Argireline, and Alpha Arbutin) to the Hyaluronic Acid gel base.
4. Stir the mixture thoroughly until all ingredients are fully dispersed and combined. Ensure the temperature of the mixture is below 30°C during mixing.
5. Check the pH of the final mixture to ensure it is within the range of 3.5-6.5, which is optimal for the stability of Argireline and Alpha Arbutin.

Storage and Shelf Life

• Storage: For long-term stability of the active ingredients, the final mixture should be stored in the refrigerator at a temperature of 4°C to 8°C.
• Shelf Life: The individual ingredients have a shelf life of at least 2 years when stored correctly in the refrigerator. Since the Hyaluronic Acid Gel Base you mentioned is preservative-free, it is highly recommended to add a suitable preservative to your mixture to prevent microbial growth and maintain stability. With proper storage in the refrigerator and the addition of a preservative, the mixture should have a shelf life of at least 1-2 years, but always observe for any changes in appearance, smell, or texture.
