Niacinamide is a popular skincare ingredient known for its ability to support the skin barrier and improve the appearance of uneven skin tone, enlarged pores and excess oil. As a form of vitamin B3, it can be found in a wide range of skincare products, particularly facial serums.

However, not all niacinamide serums are formulated in the same way. Some focus on visible pores and skin texture, while others combine niacinamide with ingredients such as tranexamic acid or exfoliating acids to target the appearance of dark spots.

If you’re looking to introduce niacinamide into your routine, choosing a formula that suits your skin concerns and tolerance is important. Here are four niacinamide serums worth considering.

 

What Makes a Good Niacinamide Serum?

When choosing a niacinamide serum, consider more than just its advertised concentration. The supporting ingredients, overall formula and your skin’s needs all matter.

  • Suitable concentration: Niacinamide concentrations vary between products. A higher percentage isn’t automatically better, particularly if your skin is sensitive.

  • Supporting ingredients: Ingredients such as panthenol, hyaluronic acid and ceramides can complement a serum by helping to keep skin hydrated and comfortable.

  • Targeted formulation: Some serums combine niacinamide with other ingredients to address concerns such as dark spots, uneven tone or excess oil.

  • Skin compatibility: Consider the full ingredient list, especially if your skin is easily irritated by fragrance or exfoliating ingredients.

  • Comfortable texture: A serum should fit comfortably into your existing routine and layer well with your moisturiser and sunscreen.

1. L’Oréal Paris Bright Reveal 10% Dark Spot Serum

L’Oréal Paris Bright Reveal 10% Dark Spot Serum is designed for those looking to improve the appearance of dark spots, post-acne marks and uneven skin tone. It’s advertised as a 10% active formula that combines 7.5% niacinamide with 2.5% amino-sulphonic acid. It also contains glycolic acid and LHA, creating a multi-active approach to skin brightening and exfoliation.

The formula is designed to target the appearance of several types of discolouration, including post-acne marks, sunspots and age spots. It also has a lightweight finish, although its combination of active ingredients may not suit every skin type.

It’s worth noting that the ingredient list also includes denatured alcohol and fragrance, which may be considerations for those with particularly sensitive skin.

 

Who it’s for: Those concerned with dark spots, post-acne marks and uneven-looking skin tone who want a serum that combines niacinamide with exfoliating ingredients.

 

Key Benefits:

  • Contains 7.5% niacinamide and 2.5% amino-sulphonic acid.

  • Includes glycolic acid and LHA to support exfoliation and improve the appearance of skin texture.

  • Designed to target the appearance of different types of dark spots.

  • Has a lightweight, non-greasy finish according to the product description.

  • Can be paired with L’Oréal Paris Bright Reveal Dark Spot Hydrating Day Cream SPF 50 as part of the brand’s recommended routine.

Summary: A multi-active option for those focusing on dark spots and uneven skin tone. Because it contains several exfoliating ingredients, introduce it carefully if your skin is sensitive or you already use other active skincare products.

 

2. Paula’s Choice 10% Niacinamide Booster

Paula’s Choice 10% Niacinamide Booster is a concentrated serum designed to improve the appearance of enlarged pores, uneven texture and post-breakout marks. It contains 10% niacinamide alongside supporting ingredients such as panthenol and acetyl glucosamine.

Panthenol helps attract and retain moisture, while acetyl glucosamine complements niacinamide in formulas targeting uneven skin tone. Together, these ingredients make it a useful option for those looking beyond niacinamide alone.

 

Who it’s for: Those looking to address visible pores, uneven texture and post-breakout marks, particularly if they want a concentrated niacinamide formula.

 

Key Benefits:

  • Contains 10% niacinamide.

  • Includes panthenol to help maintain skin hydration.

  • Contains acetyl glucosamine to complement its skin-tone-focused formula.

  • Designed to improve the appearance of enlarged pores and uneven texture.

Summary: A focused niacinamide booster with supporting ingredients for those concerned with pores, texture and uneven skin tone. It is also one of the more premium-priced options in this selection.

 

3. COSRX The Niacinamide 15 Serum

COSRX The Niacinamide 15 Serum contains 15% niacinamide, making it one of the more concentrated options in this selection. It is formulated with zinc PCA and acetyl glucosamine, ingredients chosen to complement its focus on excess oil, visible pores and post-breakout marks.

The formula also contains allantoin, which helps condition the skin. COSRX particularly recommends this serum for oily, combination and blemish-prone skin.

 

Who it’s for: Those with oily or combination skin who are concerned with excess shine, visible pores and uneven texture.

 

Key Benefits:

  • Contains 15% niacinamide.

  • Includes zinc PCA to complement its oil-focused formulation.

  • Contains acetyl glucosamine to support a more even-looking complexion.

  • Lightweight texture designed to absorb quickly.

Summary: A concentrated option for those primarily concerned with excess oil, visible pores and skin texture. Its 15% niacinamide concentration is higher than the other serums in this selection, but a higher percentage does not automatically mean better results. Those new to niacinamide may prefer to start with a lower concentration.

 

4. Anua Niacinamide 10% + TXA 4% Serum

Anua’s Niacinamide 10% + TXA 4% Serum combines three key ingredients: 10% niacinamide, 4% tranexamic acid and 2% arbutin. This combination makes it particularly relevant for those looking to improve the appearance of dark spots and uneven skin tone.

The formula also includes hyaluronic acid and ceramide NP to support hydration and skin comfort. Anua describes its texture as lightweight and watery, making it suitable for layering within a skincare routine.

 

Who it’s for: Those primarily concerned with dark spots, post-breakout marks and uneven-looking skin tone who want a serum combining several tone-focused ingredients.

 

Key Benefits:

  • Contains 10% niacinamide and 4% tranexamic acid.

  • Includes 2% arbutin to complement its tone-focused formulation.

  • Contains hyaluronic acid and ceramide NP.

  • Lightweight texture designed for everyday use.

Summary: A good option to consider if uneven skin tone and the appearance of dark spots are your main concerns. Its combination of niacinamide, tranexamic acid and arbutin gives it a more targeted formulation than a niacinamide-only serum.
