What It Does
Niacinamide, a form of vitamin B3, is studied for supporting even skin tone and barrier function. It is generally well-tolerated, making it a good option for sensitive skin that cannot tolerate stronger brightening actives.
Using It
Niacinamide can be used morning and evening. It pairs well with most other ingredients and is found in serums, toners, and moisturizers. Concentrations of 5% or less are typically sufficient.
