Why does skin aging happen so quickly despite insisting on skin care every day? In fact, everyone has ignored a very important issue - photoaging. In addition to natural aging, photoaging is also a "big killer" that affects the lifespan of skin. Oral administration of NMN has been proven to be effective in relieving photoaging.
Photoaging refers to a series of premature aging phenomena and damage that slowly occur when the skin is exposed to sunlight or other radiation sources. Among them, ultraviolet radiation has the greatest and most widespread impact. There are three main types of ultraviolet rays emitted by the sun: UVA, UVB and UVC. Among them, UVA and UVB are the main culprits that cause skin photoaging, causing the skin to gradually relax and cause thick and deep wrinkles.
In response to the damage of ultraviolet rays, most beauty lovers use sunscreen, medical beauty and other methods to resist it. The release of three new scientific research results in 2021 has promoted the celebrity anti-aging supplement NMN to the public. before.
According to the research results published by scientists in "Front Pharmacol": NMN combined with Lactobacillus fermentum TKSN041 improved the oxidative skin damage in mice caused by ultraviolet UVB irradiation, and is expected to provide a way to prevent and treat skin photoaging. Provide new treatment ideas.
After NMN treatment, the thickness of the dermis and epidermis of UVB mice returned to normal, maintaining the normal structure and number of collagen fibers, reducing the production of mast cells, and maintaining a complete and organized skin structure. . The researchers also found that NMN significantly increased the activity of serum antioxidant enzymes in mice and improved skin inflammation.
Coincidentally, on June 12, 2021, the Japanese DHC Corporation Laboratory also published a study in the "Journal of Photochemistry and Photobiology", showing that ultraviolet damage will activate the balance of NAD synthesis and NAD consumption enzymes behavior, which determines survival or dysfunction of human skin cells.
From a cell science perspective, this study from the laboratory of Japan's DHC Company concluded that ultraviolet damage to the skin caused by sun exposure will activate the balancing act of NAD synthesis and NAD consumption enzymes, which will eventually severely deplete NAD levels, thus Triggers skin cell proliferation stagnation and dysfunction, leading to aging. However, supplementing the NAD precursor molecule NMN can restore the ability of cells to recover from ultraviolet damage and restore the skin to a youthful and energetic state.
The scorching sun and strong ultraviolet rays, these "obstacles" that prevent people from going out, are gradually being overcome. Supplementing NMN can protect skin cells from ultraviolet damage, increase the skin's recovery ability after photoaging, and effectively delay skin aging.
