I have also bought your silky serum base (face/eye) and have been testing the product, it recommend 1% NaCI (pure salt) to stabilise, but further in the description it mentions using Magnesium Sulfate instead. Which version is best to stabilise this product, NaCI or Magnesium Sulfate?

For stabilizing your Silky Serum Base (Face/Eye), both 1% NaCl (pure salt) and 1% Magnesium Sulfate are recommended to enhance formula stability and prevent layer separation.

While both can be effective, the description for Silky Serum Base specifically highlights that adding 1% Magnesium Sulfate in the final step of your formulation will "help prevent layer separation well." This suggests Magnesium Sulfate is a particularly strong choice for addressing this common stability concern.

Our Silky Serum Base is designed to be compatible with ingredients containing electrolytes, so you can confidently use either NaCl or Magnesium Sulfate as a stabilizer. Both should be blended into your formula in the final step until fully dissolved.
