Glutathione is an innate substance in the human body. Its content is the highest in infants and young children, and decreases with age. In nature, it mainly exists in animal liver, yeast, muscle and blood cells. Some plants also contain high glutathione, such as tomatoes, cherries, virgin fruit (commonly known as little tomatoes), etc.
Glutathione is a tripeptide composed of glutamic acid, cystine and glycine. It is a physiological factor with a wide range of physiological functions, referred to as GSH, which is the collective name of glutathione + sulfhydryl sh. Like some whitening substances, such as tranexamic acid, glutathione is mainly used for non whitening in the early stage of clinical practice. The core role of glutathione in clinical practice is detoxification, so it plays a significant role in purifying internal organs, such as repairing liver and kidney damage, eliminating heavy metals in the body, etc. Later, it was found that glutathione can whiten skin and improve skin quality. As for how glutathione is achieved. We still have to start with the mechanism of aging and blackening of human skin.
An important cause of skin aging is free radicals
Free radicals can be said to be the "root of all evil". The most direct and obvious harm that free radicals do to us in daily life is to the skin. In healthy skin tissue, substances are stable. Therefore, when the concentration of free radicals in the human body is not very high, the body has its own maintenance system to eliminate these free radicals, which is called the antioxidant system.
In general, our body can balance free radicals, but with the deterioration of the surrounding environment, plus staying up late, drinking, smoking, and constant pressure. Free radicals in the human body become more and more, grabbing more electrons, and losing the other half of the electrons begins to go crazy, becoming extremely unstable, revenge and degeneration. As a result, one after another stains, patches and so on are left on your face, and your face begins to wrinkle, become loose and dull.
There are some free radical scavenging and antioxidant substances in our body, including superoxide dismutase (SOD), catalase, glutathione peroxidase and other enzymes, vitamin C, vitamin E, reduced glutathione, carotene and active selenium.
Glutathione plays an important role in the biochemical defense system in the human body and has many physiological functions. It can not only eliminate human free radicals, but also improve human immunity. Glutathione can maintain health, resist aging, and protect hemoglobin from oxidation by hydrogen peroxide and free radicals, so that it can continuously and normally play its ability to transport oxygen. Under the action of oxidants such as hydrogen peroxide, some hemoglobin in red blood cells oxidizes divalent iron into trivalent iron, which turns hemoglobin into methemoglobin, thus losing the ability to carry oxygen. Reduced glutathione can not only directly combine with oxidants such as hydrogen peroxide to produce water and oxidized glutathione, but also reduce methemoglobin to hemoglobin. There is a lot of glutathione in human erythrocyte, which is of great significance to protect the sulfhydryl group of protein on erythrocyte membrane in a reduced state and prevent hemolysis.
Glutathione protects the -sh group in the enzyme molecule, which is conducive to the play of enzyme activity, and can restore the active function of the -sh group in the destroyed enzyme molecule, so that the enzyme can resume its activity. Glutathione can also inhibit fatty liver caused by ethanol encroachment on the liver.
Glutathione has a strong protective effect on leukopenia caused by radiation and radioactive drugs. Glutathione can combine with toxic compounds, heavy metal ions or carcinogens that enter the human body, promote their excretion, and play a neutralizing and detoxifying role.
