Niacinamide, also known as Vitamin B3, has become one of the most sought-after skincare ingredients, known for its versatility, gentleness, and effectiveness across multiple skin issues. From treating acne to fading hyperpigmentation and strengthening the skin barrier, niacinamide delivers transformative results — when used in the right concentration.
In this detailed guide, we’ll explore how much niacinamide you should use depending on your skin concerns and how to use niacinamide serum in your daily skincare routine for maximum results.
What is Niacinamide?
Niacinamide is a water-soluble form of Vitamin B3 that plays a vital role in maintaining skin health. It helps enhance skin barrier function, improves elasticity, visibly tightens pores, and reduces inflammation. Unlike other active ingredients like retinol or AHAs, niacinamide is non-irritating and suitable for all skin types, including sensitive skin.
