Niacinamide

Niacinamide is a form of vitamin B3. This collection includes products such as serums, creams, toners and masks that list or feature it. Its presence alone does not tell you the amount, texture or purpose of the complete formula.

Use an explicit percentage supplied for the exact formula. For example, COSRX states 15% for The Niacinamide 15 Serum. An ingredient-list position, a range number or a percentage for another ingredient is not enough to calculate the niacinamide concentration. When it is not declared, treat it as unknown.

Example of a declared percentage

Choose the routine step you need. A serum offers a separate layer; a cream may let you include niacinamide in the moisturizer step you already use. Compare texture and the other ingredients instead of adding both automatically.

It can be present in the same finished formula as vitamin C. When combining separate products, check both manufacturers' instructions and introduce changes one at a time. A co-formulated serum is not evidence that every vitamin C and niacinamide pairing will suit you.

No. Niacinamide is not an AHA, BHA or PHA exfoliant. A product containing niacinamide can also contain exfoliating ingredients, so read the full formula and directions rather than classifying it by one highlighted ingredient.

Not necessarily. Check whether a product you already use contains it and identify what another step would add. Percentages from separately applied products should not simply be added into a new concentration. For a new formula, follow product-testing guidance before broader use.
