The growing popularity of Korean and Japanese cosmetics has allowed European women to get acquainted with new ingredients for them to maintain beauty. Youth, purity and firmness of the skin can provide the ash of a volcano, snake venom, snail mucin, pearl, algae and coral extract, as well as niacinamide. The last ingredient, also known as nicotinic acid, can work miracles. Niacinamide in cosmetics is used to combat comedones, hyperpigmentation and wrinkles.
What it is?
Niacinamide is nicotinic acid or the well-known water-soluble vitamin B3. This substance is vital for the existence of the human body. Vitamin B3 belongs to the group of cell-binding assets and is responsible for updating the epidermis. Niacinamide provides skin elasticity, fights against age spots and acne, gives hydration and inner radiance.
The synthesis of vitamin B3 in the human body slows down with age. This is one of the main causes of skin aging. The lack of substance reduces the microcirculation of the blood, weakening the walls of the capillaries. And also significantly dehydrates the skin, slowing down the synthesis of elastin and collagen. Fortunately, this deficit can be partially compensated.
The size of the niacinamide molecules is small, due to this they can penetrate deeply into the epidermis, restoring it at the cellular level. Niacinomide is especially valuable for the skin in that it improves the interaction of organelles, increases the synthesis of fatty acids and ceramides, and also restores healthy microcirculation in the dermis.

- Activation of the synthesis of involucrin, keratin and filaggrin.
Nicotinic acid has an antioxidant effect. It protects the DNA of cells from environmental damage and ultraviolet damage. Thanks to the effect of the substance, the barrier function of the skin is significantly increased.
Vitamin B3 not only penetrates well into the skin itself, it enhances the effectiveness of those cosmetics, which include. Therefore, retinol, peptides, hyaluronic acid or AXA acids are often added to a cream with niacinamides. Vitamin B3 is suitable for any type of skin, as it is hypoallergenic.
