Mixing Vitamins into Existing Cream

Regarding your question about mixing Stabilized Vitamin C (Natural-C Glycol), Alpha Arbutin, N-acetyl D Glucosamine, Vitamin B3 (Safe B3), and Co-enzyme Q10 into your existing skin cream:

Based on the information available, particularly for the Stabilized Vitamin C (Natural-C Glycol™) Serum, this product is designed as a ready-to-use serum and is not suitable for mixing with additional ingredients. Mixing other substances into it can affect its stability and effectiveness. This aligns with the observation made by cosmeceutical7.

For the other ingredients you mentioned (Alpha Arbutin, N-acetyl D Glucosamine, Vitamin B3 (Safe B3), and Co-enzyme Q10), while they are beneficial active ingredients, it is generally not recommended to mix raw active ingredients into a finished cosmetic product like a cream you are currently using.

Here's why:

• Stability: Finished creams have carefully balanced formulations to ensure the stability and efficacy of the ingredients. Adding raw materials can disrupt this balance, potentially causing the active ingredients to degrade or become less effective over time.
• Compatibility: The ingredients in your existing cream may not be compatible with the added active ingredients, leading to unwanted reactions, changes in texture, or reduced performance.
• Concentration and Dispersion: It is difficult to accurately determine the final concentration of the added ingredients in the cream and ensure they are evenly dispersed throughout the product without proper formulation knowledge and equipment. This can result in uneven application and unpredictable results.
• pH Issues: Some active ingredients require a specific pH range to be effective and stable. Adding them to a cream with a different pH can render them inactive or even cause irritation.

Recommendation:

Instead of mixing these ingredients into your existing cream, consider these alternatives:

• Use products that already contain these ingredients: Many serums and creams are professionally formulated with stable combinations of these vitamins and actives at effective concentrations.
• Formulate from scratch: If you are interested in customizing your skincare, learning to formulate products from raw ingredients allows you to control the composition, pH, and stability for optimal results.

Mixing raw active ingredients into a finished product carries risks and may not yield the desired benefits due to the reasons mentioned above.
