Can I Use Hyaluronic Acid With Niacinamide?
Quick answer
Yes. Hyaluronic acid and niacinamide work well together and are often combined in one product. Hyaluronic acid adds hydration, while niacinamide (vitamin B3) helps skin look more even and less shiny. Apply the thinner serum first, then the other, then moisturizer.
