“Contains 10% niacinamide and 1% hyaluronic acid.”
The 10% niacinamide + 1% hyaluronic acid composition is stated on the label and matches the product's documented formula and the specs shown.

The Inkey List Niacinamide is the budget pick that doesn't feel like a compromise. You get the same sensible 10% niacinamide as the category leaders, plus 1% hyaluronic acid that adds hydration and makes the serum gentler on the barrier — which is exactly what you want niacinamide doing. The HA base gives it a more cushioned, less potentially-drying feel than a bare niacinamide solution, and it's fragrance-free, lightweight and layers well. It skips the zinc, so The Ordinary (#1) still edges it for oily, blemish-prone skin, but for a few dollars this is a well-rounded, barrier-friendly formula most people would happily use long-term. If your budget is tight and your skin leans normal-to-dry, it's arguably the smartest buy on the page.

Read the complete Looksmaxxing guide →10% niacinamide is the same sensible, evidence-matched strength as the leaders (Bissett 2005 at 5%), so it scores high — effective for tone, oil and pores. A touch below #1 only because it's the same strength with slightly less standout support.
1% hyaluronic acid adds hydration and makes the base gentler and less drying — a genuine barrier bonus. It lacks zinc, so for oily/blemish skin the support profile is narrower than #1's, keeping it just short of the top tier here.
The HA cushion makes it feel gentler than a bare niacinamide solution, and it's fragrance-free and layers well. Still 10%, so the most reactive skin may want to start every other day.
At roughly $10 for 30 ml (~$0.33/ml) it's near-benchmark value — a few dollars for a well-rounded, barrier-friendly formula, second only to The Ordinary on pure cost.
A simple, honest actives panel and clean layering, but no antioxidant load or luxe finish — great value rather than a feature-rich formula, which is why it settles below the more elaborate picks on this axis.

“Hyaluronic acid hydrates and supports the barrier.”
Hyaluronic acid is a well-established humectant, so the hydration claim is on solid ground — it draws and holds water in the skin, which cushions the formula and makes it less potentially-drying than a bare niacinamide solution.
“Controls oil and reduces the appearance of enlarged pores.”
Niacinamide has real sebum-control evidence (Draelos 2006, 2% cut facial sebum), so the oil-control direction is supported. But the specific pore-appearance claim for this finished product is a manufacturer statement, not a result from a trial on this serum, and it carries no zinc to reinforce the oil-support side.
“Fragrance-free and lightweight.”
The fragrance-free, lightweight description is consistent with the disclosed formula and the brand's published INCI — a barrier-respecting base appropriate for a niacinamide serum.
The Inkey List gives you the same sensible 10% niacinamide as the leaders for a few dollars, plus 1% hyaluronic acid that most cheap niacinamide serums leave out. It's the rare budget pick where the formula is genuinely well-rounded rather than stripped down to hit a price.
Bare niacinamide solutions can feel slightly drying; the 1% hyaluronic acid here cushions that, drawing water into the skin and making the serum more comfortable, especially for normal-to-dry types. That hydration bump is exactly the kind of barrier support niacinamide is supposed to deliver.
The one meaningful gap versus The Ordinary (#1) is zinc. For oily, blemish-prone skin, zinc's sebum support is worth having, so #1 edges this out there. Inkey trades that for hydration instead — a better fit for drier skin, a slightly weaker one for very oily skin.
At roughly $0.33/ml it's second only to The Ordinary on cost, and under the quality-over-price rule that's a clean win because the formula is genuinely good, not just cheap. Most people could use this long-term and never feel they'd bought down.
It's still 10% niacinamide, so the most reactive skin should start every other day and build up, even with the HA cushion. The hydration helps tolerability but doesn't lower the active strength.
