Star Ingredients - Vitamin B3 (Niacinamide)


Vitamin B3, also known as Vitamin PP (for Pellagra Preventing), is a water-soluble vitamin, which groups two 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 this vitamin to stimulate collagen synthesis and to reinforce the barrier function of the skin. It increases the levels of free fatty acids and ceramides, and deeply hydrates. It produces a marked improvement in the appearance of fine lines and wrinkles. Improved barrier function may be the mechanism by which it reduces redness/ blotchiness (in Reversa anti-redness soothing care).

Niacinamide has a strong ability to interfere in the pigmentation process, thus reducing the appearance of dark spots. It brightens and evens out skin tone, reduces pore size, maintains the natural hydration, promotes microcirculation, helps reduce the appearance of signs of past damage caused by external aggressions (free radicals, blue light), and has the exceptional ability to improve the performance of many active ingredients.

Niacinamide reduces redness, dryness, and irritation caused by bacteria that live in the clogged pores of acne pimples. It also provides powerful anti-inflammatory properties and antioxidant activity. It improves the microbiome and increases the production of natural antimicrobial peptides in the skin.

In the Eye Care for puffiness and dark circles formulation, its activity on microcirculation is particularly interesting. Niacinamide helps reinforce the structure of the basal layer of the blood vessels, via its action on collagen synthesis. It helps maintain or restore a normal blood flow in capillaries via its vasculoprotective action, reducing the appearance of puffiness and dark circles under the eyes.
