Using Perfect-C and Vitamin B3 Sequentially

Hello,

You are correct that Perfect-C (Ascorbyl Tetraisopalmitate) and Vitamin B3 (Niacinamide) are often not formulated together in the same product. This is typically done to avoid potential interactions or ensure each ingredient is in its optimal pH environment for stability and efficacy.

However, applying them sequentially on the skin is perfectly fine and an effective way to use both ingredients. The key is to allow sufficient time between applications.

As the staff recommended, waiting about 30 minutes between applying the serum with Perfect-C and the cream with Vitamin B3 is a good practice. This allows the first product to be absorbed and the skin's pH to stabilize before applying the second product, minimizing any potential surface-level interactions and ensuring both ingredients can work effectively.

By applying them separately with a waiting period, your skin can effectively absorb and benefit from both Perfect-C and Vitamin B3.
