Best Niacinamide Serum for Acne Scars and Large Pores (2026 Guide)

If you're dealing with acne scars, enlarged pores, oily skin, or uneven texture, niacinamide may become one of the most valuable ingredients in your skincare routine.

Dermatologists often recommend niacinamide because it's gentle enough for most skin types while helping improve the appearance of skin over time.

What Is Niacinamide?

Niacinamide, also known as Vitamin B3, is a multitasking skincare ingredient that helps strengthen the skin barrier, regulate excess oil, and visibly improve uneven skin tone.

Unlike stronger active ingredients, niacinamide is generally well tolerated by beginners and sensitive skin.
