Vitamin B3 (niacinamide)
Vitamin B3, also known as Vitamin PP (for Pellagra Preventing), is a water-soluble vitamin, which groups 2 molecules of similar biological activity, niacin and niacinamide. Its beneficial effects for anti-age applications have been highlighted in many scientific publications.
Various studies show the ability of vitamin B3 to stimulate collagen synthesis and to reinforce the barrier function of the skin. Improved barrier function may be the mechanism by which this vitamin improves redness/blotchiness (in the anti-redness soothing care). It also possesses antioxidant and anti-inflammatory properties.
For the eye care formulation, its activity on microcirculation is particularly interesting. Vitamin B3 helps reinforce the structure of the basal layer of the blood vessels, via its action on collagen synthesis. It helps to maintain or restore a normal blood flow in capillaries via its vasculoprotective action.
