description Niacinamide Serum Overview

Niacinamide (Vitamin B3) is a powerhouse multitasker that strengthens the skin barrier, reduces visible redness, and minimizes the appearance of enlarged pores. It supports ceramide production, which is vital for maintaining skin integrity as we age. It is incredibly versatile, pairing well with almost every other anti-aging ingredient without causing irritation, making it a reliable daily staple.

help Niacinamide Serum FAQ

What percentage of niacinamide should a serum have?

Clinical studies typically use concentrations from around 4–5% upward, and most commercial serums sit between 5% and 10% — The Ordinary's popular Niacinamide 10% + Zinc 1% costs only about $6. Going above 10% mostly adds irritation risk rather than benefit.

Can I use niacinamide with vitamin C, or do they cancel each other out?

The old rule against combining them comes from mid-20th-century research using unstable pure ascorbic acid; modern formulated products work fine together, and many brands sell them in one bottle. If your skin is reactive, using vitamin C in the morning and niacinamide at night is an easy workaround.

How long before niacinamide visibly shrinks pores or calms redness?

Expect roughly 8–12 weeks of consistent once- or twice-daily use for measurable changes in pore appearance and redness, with tone and barrier benefits often appearing sooner. Consistency matters more than chasing higher concentrations.

Can I layer niacinamide with retinol or exfoliating acids?

Yes — niacinamide is stable and non-acidic, and it can actually help buffer the irritation retinoids cause. That makes it one of the easiest actives to slot into an existing routine at any step before moisturizer.
