Do you know these little things about niacinamide?

Many people must have seen the ingredient niacinamide when buying skin care products, so what exactly is niacinamide? What are the effects of niacinamide? Let’s take a look together below.

What is Niacinamide

Niacinamide is a water-soluble vitamin, also known as vitamin B3. It is a member of the vitamin family. It is also a derivative of niacin and has strong solution stability and light stability. What everyone knows about niacinamide is its whitening effect.

The main function of niacinamide

Whitening: The whitening principle of niacinamide is to interfere with the synthesis of melanin, prevent the transport of generated melanin to the epidermis, and speed up the metabolism of the epidermis to cause the cells containing melanin to fall off.

Moisturizing and repairing the skin barrier: Ceramide is an important component of the skin barrier. Topical niacinamide can increase the levels of ceramide and free fatty acids, prevent skin moisture loss, promote microcirculation in the dermis, and enhance the skin's barrier function.

Oil control: Niacinamide can reduce the production of fatty acids and triglycerides in sebum, thereby controlling oil secretion.

Anti-aging and anti-glycation: With the increase of age, the content of NADH and NADPH in cells will gradually decrease. Nicotinamide can play a role by regulating the balance of the levels of the two in the body. Glycation can cause the protein in the skin to deteriorate, resulting in yellowing, wrinkles and other problems. High levels of NADPH will exert a powerful antioxidant effect, which can prevent the spontaneous glycosylation reaction of protein and sugar, and has anti-aging and anti-glycation effects.

Will using niacinamide cause hair growth?

In one case, it is due to psychological effects. In fact, there is no hair growth, but after using niacinamide products, the skin becomes whiter, and the existing hair looks darker than before in comparison with the skin, giving the illusion of "growing hair". However, apart from this, there are indeed examples that prove that some people grow hair after using niacinamide, but there is currently no specific scientific evidence to prove why niacinamide promotes human hair growth, so I will not explain this.
