Niacinamide

A form of vitamin B3 that supports the skin barrier while helping even out tone and refine texture.

  • All skin types

What it does

Niacinamide is a versatile, generally well-tolerated active that can help with uneven tone, visible pores, and barrier support, and is commonly layered with other actives.

How it works

As a precursor to NAD+ within skin cells, niacinamide supports cellular energy processes and helps strengthen the skin's natural barrier function, which can also make other actives better tolerated.

Take care

Generally well tolerated; still patch test on first use, especially at higher concentrations, and discontinue if you notice flushing or irritation.
