Nicotinamide is a kind of skin care ingredient with a variety of functions, such as whitening, moisturizing, anti-wrinkle, whitening, etc. At present, from the application of nicotinamide, is widely used in skincare products and occupies a certain position in the field.
The whitening effect of nicotinamide has left us a very deep impression. It can play the whitening effect because nicotinamide can reduce the already produced melanin, but also can inhibit the production of melanin, from two aspects to achieve the whitening effect of melanin, but also can fade the pigmentation, and improve the skin.
Although nicotinamide has many benefits, it is not suitable for all skin types and is generally not recommended for allergic skin. In the nicotinamide products we use, there is basically more or less an impurity, nicotinic acid, which is a very irritating ingredient. Because the concentration of nicotinamide itself is 2% to 5%, and niacin is not doped much, this is why some skin is not allergic and some skin is allergic. Therefore, it is usually recommended that when choosing skin care products, try them first. If there is no allergy, they can be used normally.
