Niacinamide (Vitamin B3) – Benefits, Side Effects & Uses
Niacinamide (Vitamin B3) is one of the most researched and versatile skincare ingredients. Known for its ability to calm redness, minimise pores, and support a healthy skin barrier, it's a go-to for all skin types, from sensitive to acne-prone.
What is Niacinamide?
Niacinamide is a water-soluble form of Vitamin B3 that works with your skin's natural processes to strengthen its barrier, improve hydration, and visibly smooth texture. It is non-acidic and typically well-tolerated, even at higher concentrations.
