What Does Niacinamide Serum Do?

Niacinamide is a form of vitamin B3. It's found in foods like green peas, mushrooms, and avocados, it can also be made in a lab, and it's become a skincare superstar in recent years thanks to its ability to brighten skin, even out complexion, and diminish the appearance of pores.

Niacinamide is water-soluble, so it does a great job at hydrating the skin. It's also an antioxidant, which means it helps protect the skin from damage caused by free radicals. Free radicals are unstable molecules that can damage cells and lead to inflammation.

Niacinamide is often used in serums and moisturizers because it's an effective way to improve the appearance of the skin. For example, niacinamide serums can help with fine lines and wrinkles, dullness, and uneven skin tone. Niacinamide can also help reduce the appearance of pores and calm down redness and inflammation.

How Does Niacinamide Work?

Niacinamide works by increasing the production of ceramides. Ceramides are lipid molecules that make up the cell membranes in your skin. They help keep your skin hydrated and protected from environmental stressors like pollution and UV rays. When your cells are healthy and hydrated, they're better able to fend off damage and repair any existing damage.

In addition to increasing ceramide production, niacinamide also helps decrease inflammation. One way it does this is by inhibiting the production of enzymes that contribute to inflammation. Niacinamide also helps reduce redness by decreasing the dilation of blood vessels in the skin.
