L-Ascorbic Acid Solubility in Water-Based vs. Anhydrous Formulas and Vitamin C Formula Comparison

Question

I have two questions regarding Vitamin C formulations:

  1. Can I use regular L-ascorbic acid in water-based formulas like vitamin c e ferulic or c glutathione instead of the ultra-fine type? What is the difference between the regular and ultra-fine types in terms of formulation?
  2. What is the comparison of results or effectiveness between the vitamin c e ferulic formula (similar to Skinceuticals CE) and the vitamin c glutathione formula?

Answer

Regarding your question about the comparison between the Skinceuticals CE Ferulic formula and the Vitamin C with Glutathione formula, based on the information provided, there is no data available to compare the results of these two formulations.

Regarding the use of regular Vitamin C instead of the ultra-fine type:

  • For water-based formulas (like Vitamin C E Ferulic or C Glutathione), you can use regular L-ascorbic acid.
  • The main difference is solubility; regular type takes slightly longer to dissolve (about 3-5 minutes) compared to ultra-fine (<30 seconds), and may require a little stirring.
  • The ultra-fine type is most suitable for anhydrous (water-free) formulas where good powder dispersion is needed.
