What is Niacinamide

Walk into any skincare aisle and you'll find niacinamide on roughly half the labels. It's had a serious moment. But unlike a lot of skincare trends, this one has the research to back it up.

Here's what it actually does and why it earns its spot in a routine.

What niacinamide is

Niacinamide is a form of vitamin B3. Your body needs it to function, and your skin happens to respond really well to it topically. It's water-soluble, stable, and works across a wide pH range, which makes it one of the most versatile ingredients in skincare.

It's also one of the most well-tolerated. Sensitive skin, oily skin, dry skin, combination skin — niacinamide tends to play nicely with all of them.

What it actually does for your skin

Quite a lot, as it turns out.

It strengthens the skin barrier. Niacinamide boosts the production of ceramides and other lipids that keep the barrier intact. A stronger barrier means better hydration retention and less reactivity.

It calms redness and evens tone. It inhibits the transfer of pigment to skin cells, which over time reduces dark spots and uneven tone. It also has anti-inflammatory properties that calm redness without sedating the skin.

It minimizes the appearance of pores. Not permanently, and not dramatically, but consistently used niacinamide helps keep pores cleaner and less visible.

It regulates oil production. Good news for anyone whose skin gets shiny by midday.

Why it works so well alongside other ingredients

One of niacinamide's best qualities is that it plays well with others. It pairs well with bakuchiol, peptides, antioxidants, and most other actives without causing irritation or interaction issues. That makes it genuinely useful in a multitasking formula rather than a single-ingredient product.

How much you actually need

Studies showing significant results typically use concentrations between 2% and 5%. More isn't always better — very high concentrations can occasionally cause flushing in sensitive skin. A well-formulated product in that range, used consistently, is where the results are.

Elixir no. 1 contains niacinamide (3%) alongside beta-glucan, probiotics, bakuchiol, and peptides for barrier support that actually compounds over time. Shop Elixir no. 1 →
