What percentage of niacinamide is best?

5% to 10% delivers most of the documented benefit. Higher strengths like 15% add little for most people and raise flushing risk on sensitive skin. Start at 10%, or 5% if you are reactive.

Can I use niacinamide every day?

Yes, morning and night. Niacinamide is stable, gentle, and layers with every common active, including retinol, vitamin C, and acids.

Is The Ordinary niacinamide actually good?

Yes. Its 10% niacinamide plus 1% zinc formula at $6 is the category's value benchmark, and higher-priced serums must justify themselves against it. Texture and added extras are what you pay more for.

Does niacinamide help with acne?

Niacinamide supports blemish-prone skin by balancing oil and calming the look of redness, and zinc pairings help further. It supports rather than treats; pair it with a dedicated acne active for clearing.

What is the best niacinamide serum?

The best niacinamide serums of 2026 are The Ordinary Niacinamide 10% + Zinc 1% ($6) as the value benchmark, The Inkey List 10% Niacinamide Serum ($13) with hyaluronic acid built in, Good Molecules Niacinamide Brightening Toner ($14) for a toner format, Dr. Althea's 15% Niacinamide Purity Serum ($23.90) as the strongest K-beauty pick, and Medik8 Niacinamide Peptides ($56) for a premium peptide pairing.

Clinical reviews document niacinamide's barrier-supporting, oil-balancing, and tone-evening effects at the concentrations common in skincare.

The percentage truth

More is not better with niacinamide. Most documented benefits appear between 4% and 10%, and above that the gains flatten while flushing risk rises on sensitive skin. Pick 10% as the default, 15% only if your skin is resilient and oil is the main target, and around 5% if you are reactive.
