Ingredient decoded

Niacinamide

Niacinamide-containing moisturisers have been studied for the appearance of uneven pigmentation. The results apply to the tested formulas and do not establish how every niacinamide serum will perform.

First things first: what is it?

Niacinamide is a form of vitamin B3. You may also see it called nicotinamide.

What does it do?

Uneven-looking tone

Trials of niacinamide-containing moisturisers have found improvements in pigmentation. They tested specific formulas, not every serum with niacinamide.

Keeping moisture in

DermNet describes niacinamide as helping the outer skin layer hold on to water. Think moisture support, rather than an instant fix for every dry-skin problem.

Science or just a good story?

There are topical studies, beyond brand marketing. The tone research includes small trials, and some studies combine niacinamide with other ingredients. We have checked the abstracts; results apply to the formulas studied.

Anything to keep in mind?

Any skincare formula can cause a reaction. Test a new product on a small area first; stop using it if irritation develops.

Spot it on the label

Look for Niacinamide in the ingredient list. Nicotinamide is another name for the same ingredient.
A percentage is one formula detail. Read the rest of the ingredient list too.

So, is it a useful ingredient?

A useful ingredient to understand if uneven-looking tone or moisture support is your goal. It has research behind it, but the name on the label is not a promise that a particular serum will suit you.
