How to Make Pure Hyaluronic Acid Serum

Based on your question and the previous advice, here is a guide on how to mix a pure Hyaluronic Acid serum using two types of Hyaluronic Acid powder, along with Vitamin B3 and Allantoin as recommended.

Making a serum from Hyaluronic Acid powder requires time for the powder to fully hydrate and dissolve in water to form a gel. Adding Vitamin B3 and Allantoin first helps ensure they dissolve properly before the mixture thickens with the Hyaluronic Acid.

Ingredients (Example for 100g total)

• Water (Distilled or Deionized): Approximately 92.5 - 93g
• Safe-B3™ (Vitamin B3, Niacinamide): 4g (4%)
• Allantoin: 0.3 - 0.5g (0.3-0.5%)
• Hyaluronic Acid Powder (Type 1): 1g (1%)
• Hyaluronic Acid Powder (Type 2): 1g (1%)

• Phenoxyethanol (Extra Pure) (Preservative): 1g (1%)

• (Note: The typical recommended total concentration for Hyaluronic Acid powder in cosmetics is 0.1-0.5%. Using 1% of each type, totaling 2%, will result in a significantly thicker gel.)*

Mixing Steps

1. Prepare the Water Phase: Weigh the required amount of water into a clean container.
2. Add Vitamin B3 and Allantoin: Add the measured amounts of Safe-B3™ and Allantoin to the water. Stir or mix until both powders are completely dissolved. This is easier to do before the liquid thickens.
3. Add Hyaluronic Acid Powders: Slowly and carefully sprinkle the Hyaluronic Acid powders onto the surface of the water. Try to distribute them evenly and avoid clumping. Do not stir immediately. Allow the powder to sit on the surface for a few minutes to start absorbing water.
4. Hydrate and Gel: Cover the container to prevent evaporation. You have two options for dissolving the Hyaluronic Acid:
   • Method A (Time & Refrigeration): Place the covered container in the refrigerator for at least 3 hours, or preferably overnight. The powder will slowly hydrate and form a gel. Check periodically and gently stir if needed to help dissolve any remaining particles.
   • Method B (Blending): Use a high-speed blender (like a hand blender or immersion blender) to mix the solution for a few minutes until a smooth gel forms and no powder particles are visible.
5. Add Preservative: Once the Hyaluronic Acid is fully dissolved and you have a smooth gel, add the Phenoxyethanol (Extra Pure) preservative. This is crucial for preventing bacterial and fungal growth in your water-based serum.
6. Final Mix: Stir gently until the preservative is fully incorporated into the gel.
7. Packaging: Transfer the finished serum into a clean bottle or container.

Storage

Store the finished Hyaluronic Acid serum in the refrigerator (ideally at 4-8°C) for optimal stability and longevity. This is especially important for formulas containing Hyaluronic Acid and Allantoin, and helps maintain the quality of the serum over time.

By following these steps, you can create your own pure Hyaluronic Acid serum with the added benefits of Vitamin B3 and Allantoin.
