Niacinamide is a form of vitamin B3 that’s commonly used in skincare to support the skin barrier, calm redness, and help with oil control. It can also help fade the look of dark spots and improve the appearance of fine lines over time.

What it does

  • Strengthens the skin barrier, which helps lock in moisture and protect against irritants.
  • Reduces redness and inflammation, making it useful for sensitive, acne-prone, or rosacea-prone skin.
  • Helps regulate oil production, which may reduce clogged pores and breakouts.
  • Can improve hyperpigmentation and uneven tone by helping lessen the appearance of dark spots.
  • May soften the look of fine lines by improving hydration and supporting a healthier skin surface.

Quick note

Niacinamide is generally considered a versatile, well-tolerated ingredient for many skin types, but results depend on the formula and how consistently it’s used.
