Best Niacinamide Serums
The best niacinamide serums for pores, oil control, and skin texture, tested across concentrations and price points.
Our pick: The Ordinary Niacinamide 10% + Zinc 1% — A budget-friendly high-concentration niacinamide serum that targets blemishes and excess oil.
The Ordinary Niacinamide 10% + Zinc 1% ($6) is the best niacinamide serum because it pairs a clinically effective 10% concentration with zinc for oil control -- addressing pores, blemishes, and uneven tone in a single step at a price that makes most competitors hard to justify. It layers cleanly under every moisturizer and sunscreen I tested, causes zero irritation across skin types, and at six dollars, it removes cost as a barrier to consistent use.
