Mixing Hyaluronic Acid (Standard Molecule) Powder in a Serum

When making a serum that contains both water and powder ingredients and using Hyaluronic Acid (Standard Molecule) powder, the mixing instruction "Mix before any liquid ingredients. But after all dry powder ingredients" refers to the process of dissolving the Hyaluronic Acid powder within the water phase of your formulation.

Here is the typical mixing order:

1. Prepare your water phase. If you have other powder ingredients that need to be dissolved in water, do that first according to their instructions.
2. Add the Hyaluronic Acid (Standard Molecule) powder to the water phase.
   • Without a blender: Add the powder to the water, shake well for 1-3 minutes, and then refrigerate for at least 3 hours (or until fully dissolved).
   • With a blender: Spin the water at high speed (minimum 1,000 rpm) and gradually sprinkle the powder onto the surface while blending until it is fully incorporated and dissolved.
3. Once the Hyaluronic Acid powder is completely dissolved and the desired gel texture is achieved, you can then proceed to add other liquid ingredients or phases as required by your serum formula.

Using Double Hyaluron Liquid is an easier alternative, as suggested by the staff. Since it is already a liquid, you can simply mix it directly into the water phase of your formula without the need for the powder dissolving steps, making the formulation process much simpler.

Remember to always add a preservative like Phenoxyethanol to your formula to prevent bacterial growth and maintain the viscosity of the Hyaluronic Acid gel.
