Some skin changes arrive suddenly. Others have been accumulating for months before you notice them. Either way, finding yourself staring at three near-identical ingredient lists and wondering which one actually makes sense — that’s a reasonable place to start.
I’m not going to tell you which one is “the best.” I’m going to tell you what each of these three serums is actually designed to do — and which one makes sense for the skin you have right now.
In this guide, you’ll learn:
- What each serum’s formula genuinely offers — and what it quietly skips
- The one question that actually separates these three products
- Why Hana gives the same honest answer whether you buy the $5 bottle or the $37 one

Before You Pick: What Niacinamide Can — and Can’t — Do
Niacinamide is one of the most honestly-tested ingredients in skincare. Some research suggests it supports the skin barrier, may help visibly balance sebum, and over consistent use, could help even the appearance of skin tone and texture.
In a 12-week double-blind study published in the International Journal of Cosmetic Science, participants using a 5% niacinamide moisturizer saw improvements in the appearance of fine lines, texture, and skin tone compared to a control. A separate randomized, double-blind clinical trial found that 4% niacinamide reduced the appearance of pores and uneven skin after eight weeks of consistent use.
What it can’t do: deliver overnight results, replace the hydration layer your skin might be missing, or work identically on every person.
Concentration matters — but it isn’t the whole story. Some research indicates that preparations with 2% to 5% niacinamide may help reduce sebum production — a finding noted across multiple clinical studies in both Asian and Caucasian populations. According to the Cosmetic Ingredient Review Expert Panel’s safety assessment, clinical testing found no stinging at concentrations up to 10% and no irritation at concentrations up to 5%.
That means more isn’t automatically better. What matters more is what surrounds the niacinamide in the bottle — and whether that formula fits the actual condition of your skin right now.
A Note From Hana: Why I’m Recommending These From Tokyo
I earn the same commission rate on all three of these products. I have no financial reason to push you toward the expensive bottle. My only stake in this article is whether it helps you pick correctly — because a wrong pick doesn’t become a right one just because it was cheap.
The Ordinary Niacinamide 10% + Zinc 1% — The $5 Case
Patch test recommended, especially for sensitive skin.
This serum does what it says, cleanly and without pretense: 10% niacinamide, 1% zinc PCA, and almost nothing else. Eleven ingredients total. No fragrance. No hydration layer. No marketing language worth repeating.
What it does well: For skin that runs oily, gets congested, or wants straightforward oil balance without extra hydration — this is a research-backed starting point. The formula absorbs quickly and layers well under moisturizer and SPF. It’s The Ordinary’s best-selling product for a reason.
The honest limitation: No hyaluronic acid, no glycerin, no occlusive. If your skin is dry, barrier-compromised, or reactive, this formula works at your skin without giving anything back. It was designed for oily and combination skin, and the formula shows it. There’s also a texture note: use too much, and it pills. A drop or two — no more.
Best for: Oily or combination skin. Someone who wants high-concentration niacinamide at a price that makes consistency easy. Not for skin that’s already feeling dry, tight, or reactive — that skin needs hydration first, actives second.

Naturium Niacinamide 12% + Zinc 2% — One Step Further
Patch test recommended, especially for sensitive skin.
Sixteen ingredients. Naturium’s formula is, in its own way, a meditation on 引き算 — hikizan, the Japanese philosophy of achieving more by removing what isn’t necessary. High concentration of niacinamide, zinc PCA, glycerin, sodium hyaluronate — and then it stops.
What it does well: The 12% concentration sits above most research benchmarks, and the addition of glycerin and hyaluronic acid — both absent from The Ordinary’s formula — means this serum supports your skin’s moisture while addressing oil and texture. For skin that is navigating hormonal shifts and showing it in uneven texture, enlarged-looking pores, and a complexion that can’t quite catch up — this formula addresses all three without overwhelming a sensitive barrier.
The honest limitation: At $15.50 per fl oz, it’s an investment. At 12%, introduce it slowly if your skin is at all reactive — every other day before building to daily. Naturium’s 8-week study data comes from their own testing, not an independent academic trial. The ingredient science is solid; the brand study is supporting context.
Best for: Oily-to-normal or texture-shifting skin with a barrier that is still reasonably intact. Someone who wants The Ordinary’s clarity of approach plus hydration support.

Peach & Lily Glass Skin Refining Serum — When Niacinamide Alone Isn’t the Answer
Patch test recommended, especially for sensitive skin.
This is the serum for a different problem — not more oil or congestion, but skin that has become so reactive, so dry, so unpredictable that adding a high-concentration active feels like adding weight to something already struggling.
Twenty-three ingredients, led by four forms of hyaluronic acid, adenosine, beta-glucan, Centella-derived Madecassoside, and Dioscorea Japonica Root Extract — the Japanese mountain yam, which has long been associated with antioxidant and soothing properties in traditional use, though formal clinical studies on this specific extract in topical skincare remain limited. The niacinamide here sits at around 5% — enough to support the barrier and work gently on tone, not enough to push reactive skin further.
What it does well: WIMJ’s science-based analysis rated it 100/100 on promise delivery and low on irritation potential. This is a serum that settles first and corrects second — quietly, patiently. For skin that needs to calm before it can respond to actives, that sequencing matters.
The honest limitation: At $27.59 per fl oz, it’s the most expensive option here. The “Glass Skin” framing on the packaging overpromises — Hana does not repeat it. Some users report pilling under foundation; apply with enough time before makeup. A strong choice as a morning serum if you use a higher-strength niacinamide at night.
Best for: Dry, reactive, or barrier-fatigued skin. Someone whose skin has become sensitive after heavy actives, hormonal shifts, or exhaustion — and who needs a formula that nourishes before it corrects.

FAQ
Q: Is The Ordinary niacinamide suitable for skin navigating hormonal changes?
It depends on where your skin is right now. If your skin runs oily or combination, The Ordinary can still work well — some research suggests niacinamide may help support the barrier and reduce visible oil fluctuations that sometimes come with hormonal shifts. I’d still layer a separate hydrating serum underneath if your skin is dry beneath the oiliness. If your skin has become dry or reactive as part of those same changes, Naturium or Peach & Lily is a more complete starting point.
Q: Do I really need to spend more than $10 on a niacinamide serum?
Not necessarily — but the question isn’t just the price, it’s what the price buys you. If you have oily or combination skin and you’re consistent, the $5 bottle can genuinely serve you. If your skin is dry or barrier-compromised, spending more on a formula that includes hydration may mean you actually get results where the cheaper bottle would leave you frustrated. The wrong product at any price is the most expensive option.
Q: Can I layer two of these serums?
You don’t need to. Each is designed to work as a standalone active. If you want to use more than one, a reasonable approach is a hydrating formula in the morning and the higher-concentration one in the evening. But picking the one that fits your skin and using it consistently will serve you better than stacking.
Closing
There is no universal answer here. There is just your skin — how it feels after washing your face in the morning, what it does in the first cold week of fall, how it behaves when you’re tired. That’s the information that matters, and it belongs to you.
Pick the serum that fits where your skin actually is. Use it consistently. Notice what changes.
