Adding Glutathione to Skinceuticals C E Ferulic Serum for Stability and Whitening
Question
I would like to ask if it is possible to add Glutathione to the Skinceuticals C E Ferulic serum formula. If so, what would be its effect, particularly regarding skin whitening and the stability of Vitamin C in the formula?
Answer
Regarding your question about adding glutathione to the Skinceuticals C E Ferulic formula, I cannot provide specific formulation advice for commercial products like this. Modifying existing cosmetic formulas requires specialized knowledge in cosmetic chemistry and stability testing, as adding ingredients can significantly affect the product's stability, efficacy, and safety.
Based on the information you provided, glutathione can be added and may function as an antioxidant to help stabilize Vitamin C. However, it is generally understood that topical application of glutathione is not effective for skin whitening and its primary role in such a formula would be related to antioxidant activity rather than altering skin tone.
