As a new raw material of cosmetics, NMN has attracted much attention in the field of skin care in recent years because of its excellent anti-aging, improving skin quality, repairing skin damage and relieving skin inflammation.

First, the level of NAD+ in the human body gradually declines with age, which is one of the important reasons for human aging. As a precursor of NAD+, NMN can increase the content of NAD+ in the body, so as to effectively delay, improve and prevent aging. The Harvard University research team first discovered in 2013 that NMN can delay the aging process of mammals, which makes NMN become a research hotspot in the field of anti-aging. By increasing the metabolic activity of skin cells, NMN helps maintain skin elasticity and firmness, reduces wrinkles and sagging, and gives skin a youthful glow.

Second, NMN also has a significant effect on improving skin quality. The quality of your skin directly affects how it looks and feels. By activating SIRT1 protein deacetylase in skin cells, NMN promotes cell metabolism, thereby improving skin quality. In addition, NMN can also enhance the antioxidant capacity of the skin, resist the damage of free radicals, and reduce the damage of oxidative stress reaction to the skin. This makes the skin smoother, more even and improves the overall skin quality.

Third, NMN shows strong potential in repairing skin damage. Skin damage can be caused by a variety of reasons, such as UV exposure, chemical irritation, inflammation, etc. NMN accelerates the recovery of damaged tissues by promoting regeneration and repair of skin cells. At the same time, NMN can also promote angiogenesis, provide adequate nutrients and oxygen to the skin, and help the healing of skin injuries. In addition, NMN can also inhibit the expression of pro-inflammatory signaling factors and block the activation of inflammatory pathways, thereby reducing skin inflammation and alleviating symptoms such as redness, swelling and itching.

Fourth, NMN also has a significant effect in alleviating skin inflammation. Skin inflammation is the root of many skin problems, such as eczema, dermatitis and so on. Topical application of NMN has been shown to prevent eczema-like symptoms, including skin lesions, itching, and rashes. NMN effectively reduces skin inflammation by blocking the production of ROS (reactive oxygen species) and the activation of inflammatory pathways. In addition, NMN can also increase the protein of skin barrier function, reduce skin water loss, and relieve dry and tight skin. Together, these effects reduce skin inflammation and improve skin health.

With the continuous progress of science and technology, the application of NMN in the field of skin care is also constantly innovative. Some high-end skin care brands have begun to use NMN as a core ingredient to play its anti-aging, improve skin quality, repair skin damage and relieve skin inflammation.
