Cosmetic grade nicotinamide is a widely used skincare ingredient, it can play a role in lightening spots, anti-wrinkle, moisturizing, whitening, and other effects. Cosmetic grade niacinamide has so many effects, that we use the more the better.
From the research and testing, when the concentration of cosmetic grade niacinamide is less than 2%, its use effect is not ideal, usually, it is used in skin care products of 2%~5% concentration. Too low concentration can not play its role normally, too high concentration will increase irritation, and easily cause skin itching, redness, and other uncomfortable reactions, therefore, the concentration of cosmetic grade niacinamide needs reasonable control, so as not only to play its role as much as possible but also to avoid damage to the skin.
Our commonly used cream, essence, lotion, lotion, and other products have many products added cosmetic grade niacinamide, not only because it has multiple effects, but also because of its mature production process, and low price, for manufacturers to reduce costs.
