Niacinamide is a form of vitamin B3 that is essential for your metabolism, as it is needed to make the coenzymes NAD and NADP. It can also be used in the field of cosmetics and has several virtues, particularly in the fight against aging, irritation and inflammation of the skin. Dietary vitamin B3 deficiency causes a disease characterized by photosensitive dermatitis.
WHAT IS THE ROLE OF VITAMIN B3?
Vitamin B3 is needed to make essential coenzymes called NAD and NADP. These enzymes are indispensable because they act as energy transfer molecules in many metabolic reactions, including the breakdown of carbohydrates, lipids, proteins and alcohol, as well as in the synthesis of, for example, some hormones and some important lipids. They also have the heavy responsibility of regenerating certain molecules involved in the natural detoxification process of our body and in the antioxidant mechanisms.
BENEFITS OF NIACINAMIDE IN COSMETIC
Niacinamide is often confused with niacin, which is incorrect. Indeed, although niacinamide and niacin are both forms of vitamin B3, they have slightly different chemical structures, and only niacin (not niacinamide!) seems to cause redness. Niacinamide is therefore often the preferred vitamin B3 in skin care.
Topically applied niacinamide (vitamin B3) has been widely studied, and a number of its skin benefits have been identified. Indeed, it helps both to fight against skin aging (especially wrinkles and fine lines) and to maintain its hydration. Niacinamide even helps fight skin discoloration, redness, irritation, and inflammation. Not bad for just one ingredient!

HOW TO USE NIACINAMIDE?
IN A BODY TREATMENT
The molecule stimulates the synthesis of lipids, essential to fight against water loss from the stratum corneum. By improving lipid cohesion, it improves skin barrier function, making it less prone to dehydration. More resistant, its repair capacity is also reinforced. Lipikar AP+M balm , enriched with niacinamide, benefits from its soothing and restorative action, which potentiates the moisturizing action of the glycerin and shea butter in the balm.
IN A FACE TREATMENT
The soothing, antioxidant and anti-inflammatory properties of niacinamide make it possible to act upstream on the prevention of hyperpigmented marks. The marks on the face can be faded thanks to its action. The complexion is more even and luminous.
Niacinamide is present in many La Roche-Posay facial treatments in addition to targeted active ingredients such as salicylic acid in the Effaclar anti-blemish serum for an anti-blemish and anti-mark action. In all these treatments, it has a soothing action. Particularly in skincare specific to intolerant, allergic-prone skin, such as products in the Toleriane range , where it works alongside Neurosensine, an active ingredient developed by La Roche-Posay that reduces skin sensitivity.
Pure Niacinamide 10 Anti-Dark Spot Niacinamide Serum formulated with 10% pure Niacinamide has been designed to correct hyperpigmentation problems and prevent the appearance of pigmentary disorders, such as age-related spots (lentigo solar), melasma and residual hyperpigmentation. It is formulated with pure Niacinamide which acts on the surface and in depth, HEPES, Hyaluronic Acid and PhE-Resorcinol, active ingredients recognized for their effectiveness in controlling melanin production and improving skin radiance.
DIETARY VITAMIN B3 DEFICIENCY: RISKS FOR THE SKIN
Severe vitamin B3 deficiency causes a condition called pellagra. It is a serious condition that manifests primarily as photosensitive dermatitis, and people exposed to the sun are prone to developing a thick, scaly, heavily pigmented rash. Other symptoms include digestive disorders such as vomiting or diarrhea, and nervous system dysfunctions such as fatigue and memory loss. It is recommended to consume about 14 to 16 mg of vitamin B3 per dayand, in most cases, diet helps achieve this intake. Good amounts of this vitamin are found in chicken, turkey and salmon, but also in green leafy vegetables or legumes and seeds.
