How to use niacinamide in your routine
Niacinamide placement depends on product format and the rest of your routine. Many people use niacinamide after cleansing and before moisturiser, but product instructions vary. Check brand guidance, introduce gradually, and reduce frequency if dryness, flushing or discomfort develops. If spots, redness, irritation, pigmentation changes or breakouts are persistent, painful, scarring, spreading or worrying, consider speaking with a GP, pharmacist, dermatologist or qualified prescriber.

Before you buy
These four options break into two broad categories depending on whether you want the straightforward niacinamide format or a product that combines niacinamide with another active ingredient for a specific concern.
Niacinamide with simple serum formats
The Ordinary Niacinamide 10% + Zinc 1% and Minimalist 10% Niacinamide Face Serum are both straightforward niacinamide options with simple serum formats. The Ordinary includes 1% zinc PCA alongside the niacinamide, which may offer a complementary mechanism for oiliness. Minimalist takes a single-focus approach with no added active ingredients beyond the niacinamide. Both are water-based serums with a lightweight texture. Check the current listing for the exact format and volume included.
Niacinamide with another active for a specific concern
L'Oreal Paris Niacinamide 10% Dark Spot Corrector Serum adds an uneven tone positioning alongside the niacinamide. La Roche-Posay Mela B3 Serum combines niacinamide with vitamin C in a specialist skincare range formulation for uneven tone. Both sit at a different brand and formula positioning and are options to compare if you are specifically looking at uneven tone alongside oiliness and visible pores. Check the current listing for the exact ingredient profile, format and volume before buying.
Across all four, check the current Amazon UK listing for exact concentration, format, volume and any updates to the formula before buying.
Introduce active skincare gradually and check brand guidance before combining products. Speak to a GP, pharmacist, dermatologist or qualified prescriber if pregnant, breastfeeding, using medication, managing a diagnosed skin condition, or if spots, redness, irritation, pigmentation changes or breakouts are persistent, painful, scarring, spreading or worrying.
