How To Use Niacinamide For Amazing Skin

Before your pores absorb this skincare ingredient, it'll be comforting to know what it is exactly. Niacinamide is a form of the B3 vitamin, WebMD explains. You might see it referred to as nicotinamide. It is a vitamin found in natural meats, dairy, and produce. Our bodies need niacinamide for healthy cell production. It is not to be confused with niacin or nicotinamide riboside. Although they are also vitamin B3 family members, those compounds aren't the beloved skincare powerhouse.

Medically, niacinamide is often used to tackle vitamin B3 deficiency, per Medline Plus. It is produced as an oral supplement that, at varying degrees, is effective at slowing pellagra, type 1 diabetes, hyperphosphatemia, and osteoarthritis. In the cosmetic industry, niacinamide is a topical product. If you're not already using it, this vitamin might be the ingredient your skincare routine is missing. Applying niacinamide to your skin can favor your epidermis in multiple ways.
