Mixing Vitamin C (L-Ascorbic Acid) and Vitamin B3 (Niacinamide) Powders for Whitening Lotion

Hello, thank you for your question regarding mixing Vitamin C (L-ascorbic acid) and Vitamin B3 (Niacinamide) powders to add to your lotion for skin whitening.

Based on the information provided, it is not recommended to mix L-ascorbic acid and Niacinamide powders together directly.

This is because Vitamin C (L-ascorbic acid) and Vitamin B3 (Niacinamide) react with each other. This reaction causes the mixture to become unstable and lose its effectiveness. A simple test shows this reaction: mixing them in water will quickly turn the liquid yellow.

Therefore, mixing these two ingredients together in powder form and then adding to your lotion is not a suitable method to achieve skin whitening, as the ingredients will degrade.

To achieve skin whitening, it is important to use stable formulations where ingredients are compatible.

Regarding your questions:

1. Should other vitamins or substances be added? Since mixing C and B3 directly is not recommended, this question about adding to that specific mixture is not applicable. Achieving whitening involves using stable forms of whitening agents, potentially combined with other compatible ingredients in a properly formulated product.
2. Should the powders be mixed in equal proportions? Again, since mixing C and B3 directly is not recommended due to incompatibility, the mixing ratio for this specific combination is not relevant for achieving an effective product.

We hope this explanation is helpful.
