Niacinamide is an ingredient that belongs to the Vitamin B family. It is one of three forms vitamin B3 can take.
WHAT IS NIACINAMIDE?
This ingredient has a broad spectrum of activity to combat hyperpigmentation and uneven skin tone. Niacinamide has antioxidant and anti-inflammatory properties and is recognized to prevent and correct hyperpigmentation. It also improves skin tone and texture by enhancing skin barrier function.
HOW DOES IT WORK ON HYPERPIGMENTATION?
Skin tone and skin uniformity are directly linked to the melanin synthesis and its distribution through the
epidermis. Local excess of melanin leads to uneven complexion and dark spots.
Niacinamide both prevents and corrects hyperpigmentation in skin by:
- Inhibiting Reactive Oxygen Species, free radicals and inflammatory mediators 's release which are responsible for melanogenesis stimulation (production of melanin pigments in skin)
- Regulating the production of melanin by inhibiting Tyrosinase (the key enzyme in melanogenesis)
Finally, it reduces the diffusion of melanin thanks to its action on melanosome transfer.
An in vitro study conducted by L’Oréal Research & Innovation on reconstituted skin showed that administered niacinamide reduced the transfer of melanin to keratinocytes by 78%.
WHAT ARE THE BENEFITS OF NIACINAMIDE FOR THE SKIN?
Niacinamide is increasingly being recommended by dermatologists as an essential active to soothe and brighten the skin, creating a more even, healthy-looking complexion.
This active ingredient improves skin texture by enhancing skin barrier function as well as promoting the repair mechanisms to the outer layer of the skin.
Niacinamide also helps to fight against skin aging (especially wrinkles and fine lines) and even fight skin redness, irritation, and inflammation.
