What role does nicotinamide play in cosmetics?

1.Whitening. Nicotinamide can prevent the transformation of melanosomes from melanocytes to keratinocytes, thus reducing skin pigment deposition; At the same time, nicotinamide can also accelerate the metabolism of skin and accelerate the exfoliation of keratinocytes containing melanin.

2.Anti-aging. Nicotinamide is involved in cell metabolism and fat, protein andDNA synthesis. Therefore, nicotinamide can prevent the spontaneous glycosylation reaction between protein and glucose, thus maintaining the skin energy balance. At the same time, nicotinamide can restore cell energy, accelerate collagen synthesis and prevent collagen degradation, thus playing an anti-aging role.

3.Repair skin barrier.Nicotinamide can promote the synthesis of ceramide in skin, accelerate the differentiation of keratinocytes, and thus play a role in repairing skin barrier.

4.moisturize.Nicotinamide for external use,Can prevent the loss of skin moisture, thus achieving the role of moisturizing.

Will nicotinamide be tolerated?

Although nicotinamide has many skin care effects, it can also cause irritation to the skin. People with skin intolerance (sensitive skin, dry skin, dermatitis, etc.) are not suitable for using nicotinamide. Because nicotinamide can be decomposed into nicotinic acid in human body, nicotinic acid can promote blood vessel dilation and blood circulation, but it may also cause irritation and lead to redness and allergy of skin.

In order to avoid harm to the skin, before using nicotinamide products, you can test whether your skin is tolerant in a small area and low concentration on your face, and whether there are allergic phenomena such as redness and tingling. If there are allergic symptoms, you should stop using nicotinamide products immediately.

Can sensitive muscles still use nicotinamide?

Sensitive muscles can use low concentration of nicotinamide, and do not contain essence, preservatives and other products. Sensitive muscle stratum corneum is thin, particularly intolerant, allergic, prone to tingling and redness. Sensitive muscle whitening should pay special attention not to cause irritation to the skin and avoid aggravating skin sensitivity.

Sensitive muscle whitening should pay special attention to sun protection, ultraviolet rays are harmful to the skin and are the most important culprit in causing skin blackening. Try to choose hard sun protection methods such as wearing a hat, playing a sun protection umbrella and wearing a sun protection suit. The way of applying sunscreen is always not as cost-effective, safe and effective as hard sun protection.

Correctly look at the role of nicotinamide

Nicotinamide is not a panacea, and its whitening mechanism is to inhibit the transport of melanin, rather than reduce the production of melanin from the source. Nicotinamide is just a vitamin, so there is no need to exaggerate its efficacy. We should correctly understand and use products containing nicotinamide.
