What is Niacinamide (Vitamin B3)?

Niacinamide is a water-soluble vitamin that works with the natural substances in your skin to visibly minimize enlarged pores, tighten lax pores, improve uneven skin tone, and soften fine lines.

How It Works Under the Skin

It inhibits the transfer of melanosomes (pigment-carrying granules) to skin cells, thereby preventing dark spots. It also regulates oil production, keeping pores clear and tight.

Editor's K-Beauty Formulation Tip

K-Beauty serums often pair Niacinamide with Zinc or Hyaluronic Acid for a dual sebum-regulating and hydrating effect.
