How to Use Niacinamide

It plays well with almost everything — vitamin C, retinol, acids. Apply after watery serums and before heavier creams. A 5-10% concentration is the proven sweet spot; higher isn't better.

FAQ

Will it help acne? It reduces oil and inflammation, helping mild breakouts and post-acne redness.

AM or PM? Either or both; it's one of the most flexible actives.
