Nicotinamide is a hot product in the past two years, and even many stars are promoting it and getting a lot of praise, but many people still don't understand the efficacy and function of nicotinamide cosmetics. So, what is the efficacy and function of nicotinamide cosmetics?

Nicotinamide itself is a component of vitamin b3. At that time, the researchers found that it would make the skin white and the skin quality better after use, so they deliberately separated and extracted this ingredient from vitamin b3. Nicotinamide can inhibit the diffusion of 40% melanin to the skin surface and effectively dilute the dark spots on the skin surface.

Nicotinamide can not only be added to cosmetics now, but also the specially extracted stock solution can be used alone, or the stock solution of nicotinamide can be dropped into the usual aqueous emulsion for use. It is very convenient to use, the purity of the stock solution is higher, and the whitening and freckle removing effect is more obvious.

However, nicotinamide also has some disadvantages, because nicotinic acid rich in nicotinic acid can stimulate the skin, which may cause redness and allergies, so it needs to be measured at the first use. After the skin has established tolerance, nicotinamide can be used normally. Long-term use of nicotinamide products can also significantly increase the concentration of ceramide in the skin and make the skin barrier better.
