Ingredient efficacy

Niacinamide: does it work, and at what %?

Niacinamide is one of the actives we grade on evidence, not marketing. The benefit is real — but only when the dose clears the threshold the research supports. Here's the number, and the products that actually hit it.

2% effective dose · 5% strong

The verdict: 5% niacinamide reduced hyperpigmentation and improved barrier function in clinical studies.

How we grade Niacinamide

We check the disclosed concentration against the effective threshold from peer-reviewed dermatology literature and regulatory monographs, then weigh the formulation and any product-specific study. The grade is computed from the open rubric — re-run it on any ingredient list and you get the same letter. Also labeled as Vitamin B3, Nicotinamide.

Common questions

What concentration of Niacinamide is effective?

On Visage Theory's rubric, Niacinamide reaches an effective dose at 2% and a strong, research-backed dose at 5%. Below that, the labeled benefit is unlikely no matter how good the marketing is.

Is more Niacinamide always better?

Not necessarily — past the effective range you mostly add irritation risk, not benefit. What matters is clearing the threshold in a stable formula, which is exactly what our grade checks.

How do I know a product actually contains an effective dose of Niacinamide?

Most brands list the active but hide the concentration. When the dose isn't disclosed we can't confirm efficacy, so we withhold a grade rather than guess. Products that disclose an effective dose are graded and listed below.
