Can You Mix Niacinamide and Hyaluronic Acid?
Yes.
Yes. They're two of the gentlest, most compatible ingredients in skincare: niacinamide regulates oil and supports the barrier, hyaluronic acid hydrates. The pair suits almost every skin type, morning or night.
Regulates oil, calms breakouts, and fades post-acne marks — a form of vitamin B3.
Pulls water into the skin's surface for an instant plumping effect — apply to damp skin, then seal with moisturizer.

Why they work together
Oily skin can still be dehydrated — short on water rather than oil — and the usual fix for shine, stripping it, makes that worse. Niacinamide reduces oil production without drying skin out, while hyaluronic acid adds water without adding oil. Neither needs a ramp-up, and neither has a known conflict with the other.
How to use them together

- 2Apply hyaluronic acid.
- 3Apply niacinamide.
- 4Finish with a moisturizer — and sunscreen in the morning.
What to watch for
Very little to watch for. Hyaluronic acid works best on damp skin and sealed under a moisturizer; on bare, dry skin in a dry room it holds less water. If niacinamide causes redness, a lower strength is usually the fix.
Questions people ask
Either works. Hyaluronic acid first on damp skin, then niacinamide, is the most common order.
Yes. Both are gentle enough for morning and evening use.
