Question
Is it possible or recommended to add ingredients like Alpha Arbutin or Tranexamic Acid to the Vitamin C E Ferulic kit? What would be the effect on the formulation, particularly the stability and efficacy of Vitamin C?
Answer
Based on the feedback from other users, adding ingredients like Alpha Arbutin or Tranexamic Acid to the Vitamin C E Ferulic kit is generally not recommended.
Here's why:
- The Vitamin C E Ferulic formula is specifically designed to stabilize L-Ascorbic Acid (Vitamin C) and slow down its degradation.
- Adding ingredients like Tranexamic Acid (which has a neutral pH) or Alpha Arbutin (likely slightly acidic, but higher pH than required for Vitamin C stability) can increase the overall pH of the formulation.
- Vitamin C (L-Ascorbic Acid) requires a low pH to remain stable and effective. Increasing the pH can cause the Vitamin C to degrade much faster, reducing the efficacy of the product.
Therefore, to maintain the stability and effectiveness of the Vitamin C in the kit, it is best not to add other ingredients that could alter the pH.
