Niacinamide (B3) : Why our skin needs it ?

Niacinamide is a form of vitamin B3 which 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, in particular in the fight against aging, irritation and inflammation of the skin. A dietary deficiency of vitamin B3 causes a disease characterized by photosensitive dermatitis.


What is the role of Niacinamide ?

Niacinamide (vitamin B3) is needed to make essential coenzymes called NAD and NADP. These enzymes are indispensable because they play the role of energy transfer molecules in many metabolic reactions, including the breakdown of carbohydrates, fats, proteins and alcohol, as well as in the synthesis, for example, of some hormones and some important lipids. They also have the heavy responsibility to regenerate certain molecules involved in the natural detoxification process of our body and in the antioxidant mechanisms.

Benefits of Niacinamide

Niacinamide is often confused with niacin, which is incorrect. 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.

When applied topically it contributes first to fight against aging of the skin (especially wrinkles and fine lines) and second to maintain hydration thereof. Niacinamide even helps fight skin discoloration, redness, irritation, and inflammation. Not bad for just one nutrient!

How to use it ?

♦On Body: The molecule stimulates the synthesis of lipids, essential to fight against the loss of water from the stratum corneum. By improving lipid cohesion, it improves the skin barrier function, which is less prone to dehydration. More resistant, skin repair capacity is also enhanced. .

♦On Face: The soothing, antioxidant and anti-inflammatory properties of niacinamide make it possible to act upstream on the prevention of hyperpigmented stains. Marks on the face can be faded thanks to its action. The complexion is more uniform and luminous.

Dietery deficiency of Niacinamide: risks for skin

Severe Niacinamide deficiency causes a disease called pellagra. This is a serious disease that manifests primarily as photosensitive dermatitis, and people exposed to the sun are likely to develop a thick, scaly, strongly pigmented skin rash. Other symptoms include digestive disturbances such as vomiting or diarrhea, and nervous system dysfunctions such as fatigue and memory loss. It is recommended that you consume around 14 to 16 mg of vitamin B3 per day, and in most cases, diet will achieve this intake. You can find good amounts of this vitamin in chicken, turkey and salmon, but also in green leafy vegetables or legumes and seeds.
