High Assay Niacinamide Powder Skin whitening

Niacinamide, also known as vitamin B3 or niacinamide-type vitamin PP, is an amide form of niacin and a member of the water-soluble B vitamin family. Niacinamide is converted from niacin in the human body and is widely found in foods such as meat, fish, grains, and nuts.

As an essential nutrient, niacinamide participates in numerous important physiological processes, particularly as a precursor of the coenzymes NAD⁺ and NADP⁺, playing key roles in energy metabolism, DNA repair, cell signaling, and antioxidant processes.

Due to its skin barrier repair, whitening, anti-inflammatory, and anti-aging properties, it has become a very common active ingredient in cosmetics and skincare products.
