Niacinamide for Dark Spots: How It Works and How to Use It
Niacinamide for Dark Spots: How It Works and How to Use It
Niacinamide — also known as vitamin B3 — has become one of the most popular skincare ingredients in the UK, and for very good reason. It is effective, versatile, well-tolerated by most skin types and works particularly well for those dealing with dark spots, uneven skin tone and hyperpigmentation.
This guide explains exactly how niacinamide works on dark spots, how to use it effectively, and which Ammuri products contain it.
What Is Niacinamide?
Niacinamide is a water-soluble form of vitamin B3 that is used widely in skincare for its multi-tasking benefits. Unlike some active ingredients that target a single concern, niacinamide addresses several skin issues simultaneously — making it one of the most efficient additions to any routine.
How Does Niacinamide Work on Dark Spots?
The key mechanism behind niacinamide’s brightening effect is its ability to inhibit the transfer of melanin from melanocytes (the cells that produce pigment) to keratinocytes (the skin cells at the surface). Less melanin reaching the surface means a more even, brighter-looking complexion over time.
In addition to this, niacinamide:
- Helps to strengthen the skin barrier, reducing the inflammation that can trigger post-inflammatory hyperpigmentation (PIH)
- Supports a more even skin tone by reducing the appearance of existing dark spots
- Controls excess sebum production, which can help prevent the breakouts that lead to PIH in the first place
- Minimises the appearance of pores for a smoother, more refined complexion
What Concentration of Niacinamide Is Most Effective?
Research suggests that concentrations of 5–10% niacinamide are effective for brightening and reducing the appearance of dark spots. Ammuri’s Niacinamide Brightening Elixir contains 10% niacinamide — a well-studied concentration that delivers meaningful results without causing irritation for most skin types.
Ammuri Niacinamide 10% Brightening Elixir
Ammuri’s Niacinamide 10% Brightening Elixir is a targeted serum formulated to help even skin tone, minimise pores, control excess oil and visibly reduce the appearance of dark spots. It is suitable for daily use — morning and evening — and is compatible with most other skincare ingredients, including retinol, vitamin C and exosome serums.

What to Pair with Niacinamide for Best Results
Niacinamide + Exosome Brightening Serum
For a powerful brightening combination, layer niacinamide before Ammuri’s Exosome Brightening Serum. Together, they target pigmentation through complementary mechanisms — niacinamide inhibits melanin transfer while exosome technology supports skin renewal at a cellular level.

Niacinamide + Retinol
Niacinamide and retinol are one of skincare’s most effective pairings for dark spots. Use niacinamide in the morning and retinol at night. Niacinamide can also help reduce any potential irritation from retinol, making the combination particularly well-suited to sensitive skin.
Niacinamide + Vitamin C SPF50
Finish your morning routine with Ammuri’s Vitamin C SPF50 Day Cream. Vitamin C provides additional brightening support while SPF50 protects against UV-triggered melanin production — essential when treating dark spots.
