Niacinamide

The water soluble amide of vitamin B3 (niacin). Used in anti-ageing products, studies have shown it stimulates collagen synthesis and increases ceramide and fatty acid levels in skin. There is also evidence it reduces hyperpigmentation and increases skin lightness by inhibiting melanosome transfer from melanocytes to keratinocytes, and is therefore a popular skin lightening active. Additionally studies show topical application if four per cent niacinamide is an effective vitamin treatment for acne that does not induce bacterial resistance. In short niacinamide appears to be an effective active in treating ageing and photo damaged skin by improving skin texture, hyperpigmentation, fine lines and skin barrier function.
