What Is Niacinamide?
Share
Niacinamide (vitamin B3) is one of the most well-researched actives in skincare. It's water-soluble, stable, and works across almost every skin type — which is why it's become a cornerstone of Korean skincare formulation.
What Niacinamide Actually Does
- Brightens uneven skin tone by inhibiting melanin transfer to skin cells
- Minimizes the appearance of pores by regulating sebum production
- Strengthens the skin barrier by boosting ceramide synthesis
- Reduces redness and inflammation — making it ideal for acne-prone and sensitive skin
- Fades post-acne marks (PIH) over consistent use (4–8 weeks)
How to Use Niacinamide
Apply after cleansing and toning, before heavier serums and moisturizers. Concentrations of 5–10% are effective for most skin types; higher isn't always better. It layers well with most actives, including hyaluronic acid, centella, and even low-concentration vitamin C.
