What does the data say about The Ordinary Niacinami... vs The INKEY List 2% Hyal...?
These two serums serve quite different purposes, which makes comparing them a bit like comparing apples and oranges. The Ordinary Niacinamide 10% + Zinc 1% (£5.00, scored 84/100) is built around a clinically active concentration of niacinamide — a vitamin B3 derivative shown to regulate sebum, reduce the appearance of pores, and calm blemish-prone skin. The zinc adds mild antimicrobial support. The INKEY List Hyaluronic Acid Serum (£8.95, scored 78/100) is a straightforward hydration product using hyaluronic acid, a humectant that draws moisture into the upper layers of the skin. Neither contains the other's key ingredient, so they're genuinely targeting different skin concerns.
If your skin tends to run oily, breaks out regularly, or you're bothered by large-looking pores, The Ordinary is the clear pick — and at £5.00 with a value score of 96/100, it's genuinely hard to fault on price. The INKEY List makes more sense for dry or dehydrated skin types, or anyone new to serums who wants something simple and unlikely to cause a reaction. That said, some reviewers find the hydration underwhelming compared to other HA products, and the 30ml bottle disappears quickly with daily use.
In practical terms, both are fragrance-free and fast-absorbing, which makes layering straightforward. Neither has third-party testing verification, so you're relying on brand claims and review evidence. One thing worth noting: 10% niacinamide can cause brief flushing or tingling when you first start using it, particularly if your skin is reactive — introduce it gradually rather than twice daily from the off.
The Ordinary Niacinamide 10% + Zinc 1% is a minimal, evidence-backed water-based serum combining two well-researched actives at clinically relevant concentrations.
