Formula and How to Make Concentrated Hyaluronic Acid Serum

Okay, I understand you're looking to make a concentrated Hyaluronic Acid serum at home. Based on the staff's reply, it seems "Hayanullazi" likely refers to Hyaluronic Acid. Hyaluronic Acid is excellent for providing intense hydration to the skin.

To make a concentrated Hyaluronic Acid serum, you will need the following ingredients, equipment, and follow a specific process.

Essential Ingredients

• Hyaluronic Acid Powder or Liquid Hyaluronic Acid: This is the main ingredient. You can choose powder forms with different molecular weights or use pre-mixed liquid forms containing multiple molecular weights (like 4D or 8D Hyaluronic Acid). For a concentrated serum, you might use 1-2% of powder forms or 2-20% of liquid forms.
  • Recommendation: Combining different molecular weights, such as Standard Molecule or Large Molecule with Nano Molecule, helps provide hydration to both the outer and inner layers of the skin.
• Distilled Water or Hydrosol: This is the base of your serum. Distilled water is recommended for stability. You can also use a clean and sterilized hydrosol.
• Broad-Spectrum Preservative: Absolutely essential for water-based products to prevent bacterial and fungal growth. Choose one suitable for cosmetic use and follow the supplier's recommended usage rate.

Equipment Needed

• Accurate Scale: You need a scale that can measure small amounts accurately, preferably to 0.01g, especially for weighing Hyaluronic Acid powder and preservative.
• Beaker or Mixing Container: A clean, sterile glass or plastic beaker or container to mix your ingredients.
• Stirring Rod or Mini Mixer: To help dissolve the Hyaluronic Acid powder, which can take time and effort.
• Sterile Bottles/Containers: To store your finished serum. Use bottles with droppers or pumps.
• pH Strips or Meter (Optional but Recommended): To check and adjust the final pH of your serum to be skin-friendly (typically between 5.0 and 6.0).

Basic Formula Concept (Example for 100g)

• Distilled Water/Hydrosol: Approx. 97-98g (if using 1-2% Hyaluronic Acid powder) or 80-98g (if using 2-20% liquid Hyaluronic Acid like 4D or 8D)
• Hyaluronic Acid Powder or Liquid Hyaluronic Acid: 1-2g (powder) or 2-20g (liquid, e.g., 4D or 8D)
• Preservative: Follow supplier's recommended percentage (e.g., 0.5-1g)

Simple Steps

1. Sanitize all your equipment and workspace thoroughly.
2. Weigh the distilled water or hydrosol into your mixing container.
3. If using Hyaluronic Acid Powder: Carefully sprinkle the Hyaluronic Acid powder onto the surface of the water slowly. Do not dump it all in at once, as it can clump.
4. Let the powder "bloom" or hydrate on the surface for some time (e.g., 15-30 minutes or longer). It will start to thicken and form a gel.
5. Gently stir or use a mini-mixer to help the powder fully dissolve into a clear gel. This may take some time and patience. Avoid creating too many air bubbles.
6. If using Liquid Hyaluronic Acid (e.g., 4D Hyaluronic Acid or 8D Hyaluronic Acid): You can mix it directly into the water. Stir until combined.
7. Once the Hyaluronic Acid is fully dissolved and you have a smooth gel, weigh and add your preservative according to its recommended usage rate.
8. Stir well to incorporate the preservative.
9. (Optional) Check the pH and adjust if necessary using a dilute acid (like Lactic Acid) or base (like Sodium Bicarbonate solution).
10. Carefully transfer the finished serum into your sterile storage bottles.

Making your own cosmetics requires careful measurement, hygiene, and understanding the properties of the ingredients you are using.
