How to Layer Niacinamide and Hyaluronic Acid (Step-by-Step Guide)
If you’re wondering how to layer niacinamide and hyaluronic acid, you’re not alone. These two ingredients show up in tons of serums, and it’s not always obvious which one should go first.
Let’s answer the big question quickly, then break it down.
Quick answer:
In most routines, apply hyaluronic acid first on slightly damp skin, then layer your niacinamide serum, followed by moisturiser and SPF. If your niacinamide is thinner than your hyaluronic acid, apply the thinnest formula first.
Now let’s go through the details so you know exactly what to do and why it works.
Why Niacinamide and Hyaluronic Acid Work So Well Together
Before we talk about layering, it helps to know what each ingredient actually does.
What hyaluronic acid does
Hyaluronic acid (HA):
- Attracts and holds water in the skin
- Helps the skin look plumper and smoother
- Can temporarily soften the look of fine lines caused by dehydration
- Works for all skin types, including oily and sensitive
Think of HA as a magnet for moisture. It loves water, but it also needs to be sealed in with a moisturiser so it doesn’t evaporate.
What niacinamide does
Niacinamide (vitamin B3):
- Helps minimise the look of pores
- Balances oil production
- Fades the look of dark spots and post-blemish marks
- Supports the skin barrier, reducing redness and sensitivity
- Works for almost every skin type
Niacinamide is like a multi-tasking manager: it keeps oil, pores, and uneven tone in check while supporting your barrier.

Are they safe to use together?
Yes. Niacinamide and hyaluronic acid are very compatible. They don’t deactivate each other, and they’re both gentle, barrier-friendly ingredients. You can use them in the same routine, morning and/or evening.
The Best Order: Which Goes First – Niacinamide or Hyaluronic Acid?
There’s one simple rule in skincare layering:
Apply products from thinnest to thickest texture.
Because both niacinamide and hyaluronic acid are usually in serum form, the order can depend on the specific product. But as a simple, fool-proof routine:
- Step 1: Hyaluronic acid on damp skin
- Step 2: Niacinamide serum on top
- Step 3: Moisturiser
- Step 4 (AM): Sunscreen
Why this order works:
- Hyaluronic acid draws water into the skin when applied on slightly damp skin.
- Niacinamide layered over that hydrated base supports the barrier, pores, and tone.
- Moisturiser seals everything in and prevents the water from evaporating.
If your niacinamide serum is more watery than your hyaluronic acid, you can swap them:
- Thinner serum → goes first
- Thicker serum/gel → goes second
Both approaches are fine as long as you:
- Apply to clean skin
- Use them one after the other
- Lock them in with a moisturiser
Exact Step-by-Step Routine (AM & PM)
Here’s a simple routine you can follow as is.
Morning routine: niacinamide + hyaluronic acid
Cleanser
- Use a gentle cleanser suited to your skin type.
- Pat skin dry, but leave it very slightly damp if you can.
Hyaluronic acid serum
- Apply 1–2 pumps or a few drops.
- Spread over the face and neck while the skin is a bit damp.
- Don’t wait until skin is bone dry.
Niacinamide serum
- Apply a thin layer on top.
- Focus on oily areas, visible pores, and areas with dark spots if you like.
Moisturiser
- Use a light gel-cream if you’re oily, or a richer cream if you’re dry.
- This step is crucial to “seal in” hyaluronic acid.
SPF 30 or higher
- Every morning, even if it’s cloudy.
- Niacinamide works brilliantly in brightening routines, but UV exposure can worsen dark spots, so sunscreen is non-negotiable.
Evening routine: niacinamide + hyaluronic acid
- Cleanser (double cleanse if wearing makeup/SPF)
- Hyaluronic acid serum on damp skin
- Niacinamide serum
- Moisturiser/night cream
You can use them every day, both morning and night, as long as your skin feels comfortable.
How Much Should You Use?
More is not always better. Aim for:
Hyaluronic acid:
- About a pea-sized amount, or a few drops
- Enough to lightly coat the skin without feeling sticky or heavy
Niacinamide:
- Another pea-sized amount or 2–3 drops
- Most people do well with 5–10% niacinamide; very high percentages can sometimes cause flushing or irritation
If skin ever feels tight, sticky, or suffocated, you might be applying too much product or skipping moisturiser.
Common Mistakes When Layering Niacinamide and Hyaluronic Acid
Avoid these easy mistakes, and you’ll get better results:
1. Applying hyaluronic acid to bone-dry skin
Hyaluronic acid works best with water. On very dry skin, especially in a dry climate, it can pull water from deeper layers and leave you feeling more dehydrated.
Fix:
Apply it on slightly damp skin (after cleansing or a hydrating mist), then always follow with moisturiser.
2. Skipping moisturiser
If you stop at serums, you’re not sealing in that hydration.
Fix:
Even oily skin benefits from a light, non-comedogenic moisturiser on top of niacinamide and HA.
3. Using too many activities at once
Niacinamide and hyaluronic acid are gentle, but if you also add strong acids, retinoids, and vitamin C in one routine, skin can feel overwhelmed.
Fix:
- Keep niacinamide + HA as your hydrating, barrier-supportive base.
- Rotate stronger actives (like exfoliating acids or retinoids) on alternate nights if needed.
Skin Type Tips
Oily / acne-prone skin
- Use a light gel cleanser.
- Choose water-light serums for both niacinamide and hyaluronic acid.
- Niacinamide can help with oil control and post-blemish marks, while HA keeps you hydrated without heaviness.
Dry/dehydrated skin
- Look for a creamy cleanser that doesn’t strip the skin.
- Use hyaluronic acid on very slightly damp skin, then niacinamide.
- Choose a richer moisturiser with ceramides, squalane, or fatty acids.
Sensitive / redness-prone skin
- Both niacinamide and hyaluronic acid are usually well-tolerated.
- Start slowly: once a day, then build up to twice a day if your skin is happy.
- Avoid high-percentage niacinamide (above 10%) at first.
Can You Use Niacinamide and Hyaluronic Acid With Other Actives?
Short answer: Yes, but be strategic.
With retinol:
Use hyaluronic acid and niacinamide in the same routine as retinol to support hydration and barrier strength.
- Typical order at night: cleanse → hyaluronic acid → niacinamide → retinol → moisturiser.
With vitamin C:
- Many people use vitamin C in the morning, and niacinamide + HA either alongside it or at night.
- Modern formulations of niacinamide + vitamin C together are generally fine for most skin.
With exfoliating acids (AHA/BHA):
- Use acids 1–3 times a week, then follow with hyaluronic acid and niacinamide to calm and re-hydrate.
Always patch test if you’re adding a new active.
FAQs: Niacinamide and Hyaluronic Acid Layering
Q: Can I use niacinamide and hyaluronic acid every day?
Yes. Most people can use both daily, morning and night, because they are gentle, hydrating, and barrier-friendly.
Q: What if my niacinamide and hyaluronic acid are in the same serum?
That’s totally fine. Many formulas combine them. Just apply that serum after cleansing, then follow with moisturiser and SPF in the morning.
Q: Is it better to use them in the morning or at night?
Both work.
- Morning: helps with hydration and oil control under makeup and SPF.
- Night: supports repair and barrier recovery while you sleep.
Q: Can niacinamide or hyaluronic acid cause purging?
They don’t typically cause “purging” because they’re not strong exfoliants. If you get irritation or breakouts, stop, simplify your routine, and reintroduce slowly or choose lower strengths.
Key Takeaways
If you only remember three things about how to layer niacinamide and hyaluronic acid, let it be these:
- Apply to clean, slightly damp skin.
- Use hyaluronic acid first, then niacinamide, then moisturiser (and SPF in the morning) – or simply follow the rule: thinner formula first.
- Be consistent. These are gentle, long-game ingredients that work best with daily use, not just once in a while.
Use this routine consistently for a few weeks, and you should see skin that feels more hydrated, looks smoother, and behaves more calmly overall.
