Niacin functions as a skin-conditioning agent and is closely related to niacinamide, the more common B3 derivative in skincare. In a formula it helps support the skin's surface and overall feel. It is water-soluble and blends easily into water-based products.

The niacin used in cosmetics is typically produced synthetically, which makes it suitable for vegan formulas. Because sourcing can vary by manufacturer, anyone seeking a certified vegan product should check the brand's labeling.
