How to Thicken Vitamin C Serum?

The most straightforward method to thicken vitamin C serum is by adding hyaluronic acid.

Here's a more detailed breakdown:

Dissolve the Vitamin C: Ensure your Vitamin C powder (usually L-Ascorbic Acid) is completely dissolved in distilled water first. This is crucial for even distribution and efficacy.
Introduce Hyaluronic Acid: Add hyaluronic acid powder to the Vitamin C solution. Be prepared for it to look lumpy initially – this is normal.
Chill the Mixture: Refrigerate the mixture for approximately one hour. This allows the hyaluronic acid to fully hydrate and dissolve.
Observe the Change: After chilling, the hyaluronic acid should dissolve, noticeably thickening the serum.

Important Considerations:

Hyaluronic Acid Concentration: Experiment with different concentrations of hyaluronic acid to achieve your desired thickness. Start with a small amount and gradually add more until you reach the desired consistency. Be careful because too much Hyaluronic Acid can make the serum sticky.
Quality of Ingredients: Use high-quality hyaluronic acid and L-Ascorbic Acid (Vitamin C) for the best results. Look for reputable suppliers.
pH Level: The ideal pH for Vitamin C serum is between 2.0 and 3.5 for optimal absorption. Hyaluronic acid can sometimes affect the pH, so testing and adjusting it is recommended. You can use pH strips to measure and adjust with a bit of citric acid or baking soda, if necessary.
Antioxidant Boosters (Optional): You can also consider adding other water-soluble antioxidants like ferulic acid or Vitamin E to improve stability and efficacy. However, this won't directly thicken the serum.
Storage: Store your homemade Vitamin C serum in a dark, airtight bottle in the refrigerator to prolong its shelf life. Vitamin C degrades when exposed to light and air.

Alternative Thickeners (Less Common):

While hyaluronic acid is the most common and effective, other ingredients that might be used, though potentially altering the serum's feel, include:
