Adding L-Ascorbic Acid Powder to Stabilized Vitamin C Serum

Mixing Vitamin C (L-ascorbic acid) (Ultra-Fine) powder directly into Stabilized Vitamin C (Natural-C Glycol™) Serum is not recommended.

Here's why:

• Stabilized Serum Formula: The Stabilized Vitamin C (Natural-C Glycol™) Serum is a pre-formulated, stable base containing 15% L-Ascorbic Acid. It is designed as a finished product.
• Stability Issues: The manufacturer explicitly states that this serum base is not suitable for mixing any additional ingredients because it may affect the stability of the vitamin C. Adding L-ascorbic acid powder (which is inherently less stable when dissolved in water-based formulas like serums) will likely destabilize the entire product, causing the vitamin C to degrade quickly and lose its effectiveness.
• L-Ascorbic Acid Powder Usage: Vitamin C (L-ascorbic acid) powder, especially the Ultra-Fine grade, is typically recommended for use in specific formulations, such as anhydrous (water-free) systems, where its stability can be better maintained.

To increase the vitamin C concentration, it is generally better to use a product with a higher concentration from the start or formulate a serum from scratch using appropriate ingredients and stabilizers for L-ascorbic acid powder. Modifying a pre-made stabilized serum base is not advisable due to the risk of compromising its stability and efficacy.
