Ultra-low allergenicity nicotinamide, as a form of Vitamin B3 (VB3), possesses multiple skincare benefits while simultaneously reducing skin irritation and sensitivity. This characteristic has garnered widespread attention and application in skincare products.

Firstly, ultra-low allergenicity nicotinamide inherits various skincare functions of nicotinamide. It effectively inhibits melanin transfer, reduces melanin production, thereby achieving whitening effects. Additionally, it stimulates collagen synthesis, reducing wrinkles, redness, pigmentation, and other signs of aging skin, thus providing anti-aging benefits and restoring skin's hydration and elasticity. Moreover, nicotinamide is also used in the medical field to treat conditions such as rough skin, stomatitis, liver diseases, and sun-induced dermatitis.

However, the use of nicotinamide in skincare products also carries certain risks. Due to the potential presence of trace amounts of nicotinic acid in nicotinamide raw materials, it may cause skin irritation and itching in some individuals. Therefore, the development and application of ultra-low allergenicity nicotinamide are particularly important.

During the manufacturing process of ultra-low allergenicity nicotinamide, the content of nicotinic acid is strictly controlled, significantly reducing its potential for skin irritation and sensitivity. Additionally, its extremely small molecular weight allows it to penetrate deeply into the skin's layers, effectively delivering its benefits.

In conclusion, ultra-low allergenicity nicotinamide is a high-quality skincare ingredient that maintains its original efficacy while greatly reducing skin irritation and sensitivity. It effectively addresses various skincare concerns, helping individuals achieve healthy, beautiful skin.

Chinese factories utilize full-enzyme production processes to produce the ultra-low allergenicity nicotinamide, with nicotinic acid content < 20ppm, meeting the demands of the skincare product market.
