Niacinamide, also known as Vitamin B3 or nicotinamide, is a water-soluble vitamin that has gained significant popularity in the skincare industry for its various benefits for the skin. It is a versatile and well-tolerated ingredient suitable for various skin types. Here are its primary function and applications:
