Frequently asked questions

Is niacinamide the same as niacin?

They are two forms of vitamin B3 and are closely related, but they are not identical compounds. Niacin is the acid form and niacinamide is the amide form; skincare products almost always use niacinamide.

Why does niacinamide appear on so many ingredient lists?

It dissolves in water, is stable in a wide range of formulas and sits comfortably alongside many other common ingredients, which makes it easy for manufacturers to include. Its popularity is partly a formulation convenience.

What does the percentage on a niacinamide product mean?

It states the concentration of the ingredient in the formula by weight, so a five per cent product contains five parts niacinamide per hundred parts of the total mixture. A higher number is not automatically a better formula, since the rest of the ingredients matter too.
