Niacinamide Benefits: Why a Higher Percentage Isn’t Always Better

2 min read Oct 27, 2026

Niacinamide appears in serums, moisturisers, and routines for several different skin concerns. Its versatility can make it useful but it can also make choosing a product confusing.

Niacinamide is a form of vitamin B3. Topical formulations have been studied for benefits including support for the skin barrier and improvements in uneven pigmentation. Results depend on the formulation and use; the ingredient name alone does not guarantee a particular outcome.

Begin with the benefit you want

Ask why you are considering niacinamide.

Do you want a moisturiser for everyday comfort? A serum to support a hydration-focused routine? A product that fits care for uneven-looking tone?

These questions help narrow the choice more effectively than searching for the largest percentage printed on a bottle.

A concentration is one piece of information

The percentage tells you how much niacinamide a product contains. It does not describe the entire formula, its texture, the other ingredients, or how your skin will tolerate it.

A higher percentage is not proof that a product will work better for you. Likewise, an undisclosed percentage does not allow you to estimate strength from the ingredient list alone.

Look for clear product information and choose around your needs.

Do you need a separate niacinamide serum?

Not necessarily. Your moisturiser or existing serum may already contain it.

Before adding another product, read the formulas you use. If niacinamide already has a place in your routine, you may prefer to keep that step rather than duplicate it.

This is particularly useful when simplifying skincare: one well-chosen product can contain several ingredients with complementary roles.

Introduce it thoughtfully

Keep your other products steady while trying something new. If you notice persistent irritation, stop and reconsider the formula rather than assuming your skin must push through it.

Judge a product by how it fits your routine over time, not only by how impressive its label sounds.
