Niacinamide is also known as vitamin B3. It’s considered a fan favourite among many skincare enthusiasts, including those with sensitive skin because of how gentle and anti-inflammatory this ingredient is. 

Niacinamide can help with the appearance of fine lines and wrinkles while improving skin firmness due to its ability to encourage the collagen synthesis process and the production of three important proteins for your skin: keratin, filaggrin and involucrin. This means your skin has a better overall structure, a smoother texture, and is more resilient.

Niacinamide also brightens skin and helps with hyperpigmentation through suppressing melanin from the melanocytes. This translates to pigmentation like dark spots not being able to reach the top layer of the skin as easily.

Niacinamide is most well known for being great for healing acne, congestion, and enlarged pores. That's because niacinamide regulates sebum production and is anti-inflammatory—making it able to address inflamed or irritated acne. Plus, niacinamide increases the production of ceramides in your skin, strengthening your skin barrier and protecting you from further breakouts brought on by external causes.
