Nicotinamide is an important ingredient commonly used in skin care products. Its main functions include whitening, moisturizing, moisturizing, shrinking pores, and anti-wrinkle.
Nicotinamide is a member of the B vitamin group, also known as vitamin B3. Nicotinamide raw material price is not expensive, but the price of skin care products with nicotinamide is very different, this is because of nicotinamide purity, production process, matching ingredients, and other factors so the price is high and low.
Nicotinamide is not suitable for everyone’s skin. The purity of nicotinamide is too high, the purification process is poor, and PH value is the main factor affecting allergy when we use skin care products containing nicotinamide.
If you are using the skin care products containing nicotinamide for the first time, and have a history of allergy, or worry about skin tolerance, then we suggest that you can apply a small amount of the product behind the ear or the local cheek, observe the trial situation, if the skin is not uncomfortable, you can use the product normally, if there is an allergic phenomenon, need to pause, after the skin recovery, Tolerance can be established before normal use. In addition, if the skin barrier has been significantly damaged, such as dry peeling, a sensitive phase, we usually recommend using nicotinamide skin care products after the skin barrier repair.
