Niacinamide PC (Vitamin B3)

 

Niacinamide is a multitasking ingredient, water-soluble, and structurally stable in the presence of heat and light. Clinical studies have shown that topical use of Niacinamide stabilizes epidermal barrier function, or a reduction in transepidermal water loss and an improvement in the moisture retention of skin. It increases protein synthesis (such as keratin), helps stimulate ceramide synthesis, treats uneven skin tone, brightens, and mitigates post-inflammatory hyperpigmentation, among other benefits for skin. In aging skin, topical application of Niacinamide improves the surface structure, smoothes out wrinkles and prevents photocarcinogenesis. It has also demonstrated anti-inflammatory effects in acne, rosacea and certain types of irritation. Niacinamide is highly regarded suitable for use as an ingredient in cosmetic products due to these many benefits.
