Adjusting Viscosity of Vitamin C E Ferulic (Lite) Serum Kit

Subject: Adjusting Viscosity of Vitamin C E Ferulic (Lite) Serum Kit

Regarding your question about adjusting the viscosity of the Vitamin C E Ferulic (Lite) serum kit (Product ID 70):

Based on the staff's response:

• Reducing the amount of distilled water (Product ID 838) in the formula is not recommended, as it may cause issues with the stability or efficacy of the serum.
• Adding Hyaluronic Acid is a suitable method to increase the viscosity without negatively affecting the other components of the formula.
• The staff specifically recommends using Hyaluronic Acid (Large Molecule) (Product ID 1351) over other types like Double Hyaluron Liquid (Product ID 404) because it provides the maximum gelling effect.

Regarding the quantity to add:
A specific amount was not provided in the response. To achieve your desired viscosity, you can try adding Hyaluronic Acid (Large Molecule) gradually. A common starting point for increasing viscosity with Hyaluronic Acid is a low percentage, perhaps starting from 0.1% to 0.5% of the total serum volume. Add a small amount at a time, mix thoroughly, and check the consistency until you reach the desired thickness.
