Why you should trust this review
I am a licensed esthetician and skincare formulator with 9 years of beauty testing experience. For this review I purchased The Ordinary Niacinamide 10% + Zinc 1% at full retail in January 2026, Deciem did not provide a sample. Across the past 4 months I led a 12-week panel test with 5 testers covering combination, oily, normal, and acne-prone skin types, with biweekly photo logging and a standardized oil control and pore assessment.
How we tested the niacinamide serum
Our active serum protocol takes 12 weeks minimum per tester. We logged morning and night application, tracked T-zone shine via blotting paper assay at hour 4 and hour 8, monitored pore appearance with macro photography, and cross checked against barrier baselines at week 0, 4, 8, and 12.
Value
At $9 the The Ordinary Niacinamide 10% + Zinc 1% is the right Beauty & Personal Care in 2026.

Should you buy the The Ordinary Niacinamide 10% + Zinc 1%?
The Ordinary Niacinamide 10% + Zinc 1% is a water-based serum with a high dose of niacinamide for oil regulation and pore appearance. After 4 months of daily use and a 12-week panel test across 5 testers, it visibly reduced midday shine on the T-zone and slightly tightened pore appearance on the nose and cheeks. At $9 for 30ml, the value is exceptional and the formula is well built. The trade is occasional pilling under sunscreen for one of the best-priced actives in skincare.
Frequently asked questions
Is The Ordinary Niacinamide 10% worth $9 in 2026?+
Yes, this is one of the best value buys in skincare. The 10% niacinamide concentration is high enough to deliver real oil control and pore appearance benefits, and at $9 for 30ml the cost per use is negligible. Start once daily, then layer it under sunscreen with a 2 minute pause to avoid pilling.
