Niacinamide has become one of the most popular skincare ingredients in the UK market, and for good reason. It is well tolerated by most skin types, addresses multiple concerns simultaneously, and is available across a wide price range. Whether you are managing oily skin, dealing with enlarged pores, or trying to fade post blemish marks, niacinamide has something to offer.
This guide cuts through the noise and focuses on what is actually worth buying in the UK right now. Every product listed has been evaluated on formulation, concentration, price, and real world reception from people using them.
What to Look for in a Niacinamide Serum
Concentration: Five to ten percent is the sweet spot. Below five percent and you may not see results. Above ten percent and you run into diminishing returns and potential irritation. The Ordinary, Inkey List, and La Roche-Posay all sit in this range.
Additional ingredients: Niacinamide pairs well with other actives. Zinc PCA adds oil control. Hyaluronic acid adds hydration. Ceramides support the skin barrier. Peptides complement the skin tone benefits. What you want alongside niacinamide depends on your primary skin concern.
Fragrance: Avoid fragrance in niacinamide serums, particularly if you have sensitive or reactive skin. The Ordinary, Inkey List, and La Roche-Posay are all fragrance free. CeraVe is also fragrance free and formulated for sensitive skin.
Formula texture: Niacinamide serums are generally water based and lightweight. This makes them easy to layer into a routine. Heavier formulations with additional actives may work better in the evening than the morning.
The Best Niacinamide Serums Available in the UK
Niacinamide 10% + Zinc 1%
ASIN: B01MDTVZTZ
The Ordinary Niacinamide 10% + Zinc 1%
From around £4.50 on Amazon UK
The Ordinary Niacinamide 10% + Zinc 1% is the highest-selling niacinamide product in the UK market. The ten percent concentration is at the upper end of the effective range without pushing into territory where irritation becomes common. The one percent zinc PCA adds a secondary oil-control mechanism on top of what niacinamide already does. The formula is water based, absorbs quickly, and does not leave a sticky residue. It works well under moisturiser or sunscreen in the morning, or layered with other actives in the evening.

ASIN: B09N9Z7NBS
The Inkey List 10% Niacinamide Serum
From around £9.99 on Amazon UK
The Inkey List takes a different approach to most niacinamide serums by including one percent hyaluronic acid alongside the ten percent niacinamide. This matters in practice. Pure niacinamide serums can feel slightly drying on some skin types, particularly in winter or on already dry complexions. The hyaluronic acid counteracts this by drawing moisture into the skin alongside the niacinamide working on oil control and pore appearance. The result is a more balanced formula for people whose primary concern is not pure oiliness but combination skin that is dry in places and shiny in others. Fragrance free and straightforward to use in any routine.

La Roche-Posay Niacinamide 10% Pure Serum
From around £17.00 on Amazon UK
La Roche-Posay occupies a different category from The Ordinary and Inkey List. Their Niacinamide 10% Pure Serum is part of their specialist dermatological range, formulated with their thermal water as a base ingredient. The concentration is ten percent, sitting at the top of the effective range. What sets it apart is the formulation environment. La Roche-Posay products are tested on sensitive skin and designed to minimise the risk of reaction. If you have tried niacinamide before and found it irritating, or if you have generally reactive skin that responds poorly to products with a strong actives focus, this is the version worth trying. The price reflects the brand positioning but the formulation is genuinely different from the budget options.

ASIN: B0B913JC2W
CeraVe Resurfacing Retinol Serum
From around £17.61 on Amazon UK
CeraVe occupies a specific niche in the niacinamide conversation. Their Resurfacing Retinol Serum is not a straight niacinamide product. It combines retinol with niacinamide and ceramides, which makes it more comparable to a retinol serum with barrier-support benefits than a traditional niacinamide serum. What makes it relevant here is that buyers searching for niacinamide serums frequently encounter it, and it genuinely belongs in the consideration set for people who want to introduce retinol but are concerned about irritation. The ceramides and niacinamide together reduce the barrier disruption that retinol can cause. If you want niacinamide and retinol in one product, this is the most evidence-backed option available in the UK at this price point.

Beauty of Joseon Relief Serum
From around £14.00 on Amazon UK
Beauty of Joseon is a Korean skincare brand that has built a strong following in the UK through the K-beauty market. Their Relief Serum combines niacinamide with centella asiatica and propolis, giving it a different character from the Western-focused formulations. Centella adds calming and skin-barrier-supporting properties, while propolis has antimicrobial benefits that complement niacinamide for blemish-prone skin. The formula is lightweight, absorbs quickly, and does not pill under makeup or sunscreen. It has become popular among people who prefer the K-beauty approach to actives and want something that sits alongside their existing routine without adding friction.

Eucerin Hyal-Urea Face Cream
From around £13.00 on Amazon UK
Eucerin's Hyal-Urea face cream is not a serum in the conventional sense. It is a moisturiser formulated with five percent urea and five percent niacinamide. Urea is a naturally occurring moisturising factor in the skin that decreases with age and dryness. Combined with niacinamide, it targets both hydration and skin tone simultaneously. This product makes sense for people over thirty who are dealing with both early signs of ageing and uneven skin tone, particularly in the dry skin category. The formula is richer than a serum and works best as a moisturiser step rather than layered under one. If you want a niacinamide product that also does the job of your moisturiser, this is the most evidence-backed option in the UK market.
View on Amazon UKHow to Use Niacinamide in Your Routine
Niacinamide is one of the most flexible actives you can introduce to a skincare routine. Apply it after cleansing and any water-based toners, before heavier serums or moisturisers. It works in both morning and evening routines.
The one thing to be aware of is high-concentration vitamin C. When vitamin C and niacinamide are combined, a small percentage of people experience flushing or irritation. This is not dangerous but it can be uncomfortable. If you use both, apply them at different times of day · niacinamide in the morning, vitamin C in the evening, or alternate days entirely.
Niacinamide pairs well with retinol, AHAs, BHAs, hyaluronic acid, and ceramides. If you are introducing it alongside other actives, add it gradually so your skin can adjust. Start with once daily and move to twice daily once your skin has settled.
The Bottom Line
Most people starting out with niacinamide should begin with The Ordinary Niacinamide 10% + Zinc 1%. It is affordable, effective, and straightforward. If you find it drying or if you have combination skin, step up to the Inkey List. If you have sensitive or reactive skin and want the assurance of a dermatological brand, La Roche-Posay is worth the price difference.
