Niacinamide

Niacinamide, also known as vitamin B3, is one of the most scientifically documented cosmetic actives. Its versatile profile and very good tolerance make it suitable for many skin types.
It is linked, according to available data, to skin comfort and preservation of hydration comfort against external factors such as pollution and hard water. This comfort support is documented without requiring a specific skin barrier study on the finished product.
Its antioxidant properties are documented and linked to protection against oxidative stress, a factor contributing to visible signs of aging: pigmentation irregularities, fine lines, texture appearance.
Niacinamide is associated, according to available data, with visible reduction of fine lines and improvement in skin texture. It also supports mechanisms involved in maintaining skin structure, linked to more toned-looking skin.
Its action on imperfections and visible shine is documented, making it particularly suitable for oily or blemish-prone skin. It is also linked to documented regulation of sebum appearance, for a more matte-looking complexion.
Its documented soothing properties help reduce redness appearance and improve comfort for sensitive or reactive skin.
Practical note: niacinamide is compatible with most cosmetic actives. It pairs particularly well with hydrating actives, antioxidants, and complexion-unifying ingredients. It has no documented incompatibility with peptides, unlike pure vitamin C.
In summary, a versatile and well-tolerated vitamin, linked to skin comfort, complexion uniformity, visible reduction of imperfections, and protection against oxidative stress.
