Niacinamide (Vitamin B3)

Niacinamide, also known as vitamin B3, is a water-soluble vitamin that plays an essential role in maintaining healthy skin function. It is involved in cellular energy production and DNA repair, which makes it highly effective when used in topical skincare. Niacinamide is commonly formulated in niacinamide serum products because of its stability and ability to work at the skin’s surface as well as deeper layers. When applied regularly, it helps strengthen the skin barrier by increasing ceramide production, which reduces moisture loss and improves overall skin resilience.

Niacinamide is widely used in skincare because of its multi-targeted benefits. It helps regulate excess oil production, reduce the appearance of enlarged pores, calm inflammation, and improve uneven skin tone. Clinical studies show that niacinamide can also reduce hyperpigmentation by slowing the transfer of melanin to skin cells, while simultaneously improving skin texture and hydration. Since it is well tolerated by most skin types, niacinamide is considered a reliable ingredient for long-term skin health, clarity, and balance.
