If you are interested in skin whitening, you must have heard of ‘Glutathione’. Glutathione is known as the main ingredient of White Jade Injection, and is attracting attention as a whitening agent. But in fact, glutathione is not known for its whitening effect, but as a powerful antioxidant. I learned more regarding the efficacy of glutathione that I had not known regarding in the meantime.

What is ‘Glutathione’?
Glutathione is a protein made up of three amino acids: glycine, cysteine, and glutamic acid. Glutathione is an antioxidant that is produced primarily in the liver. However, the production of glutathione in the body gradually decreases with age. What changes will happen to your body if this happens?
Powerful Antioxidant ‘Glutathione’
Humans need oxygen to sustain life. However, if oxygen is used in excess and is left over, active oxygen, which is harmful to the body, is created. Active oxygen, which is in an unstable state, easily reacts with other molecules and causes harmful effects to the human body, such as oxidizing and damaging cells. Oxidative stress due to excessive active oxygen can cause chronic diseases such as diabetes or high blood pressure, heart disease, and rheumatoid arthritis. This is why it is necessary to properly remove active oxygen accumulated in the body.
What is needed to remove excessive active oxygen in the body is the antioxidant function. Glutathione helps to destroy active oxygen in the body so that it can be discharged out of the body.
Glutathione’s ‘improvement of liver level’ effect
Glutathione is used as a medicine for the liver. This component is present in the highest concentration in the liver. This means that the liver uses a lot of glutathione. The liver detoxifies various toxic substances, including various drugs and alcohol, and a large amount of active oxygen is generated in this process. Antioxidant action of glutathione is very important to protect hepatocytes from active oxygen.
In fact, according to one study, when patients with non-alcoholic fatty liver took 300 mg of glutathione per day for 4 months, ALT levels, a type of liver level, significantly decreased.
The ‘skin whitening’ effect of glutathione
Glutathione also acts on melanocytes in our skin. Melanin is the pigment that determines the color of the skin. Glutathione inhibits the activity of a component that makes black melanin. It produces a whitening effect by inducing brown melanin to be produced instead of dark black melanin.
Glutathione, oral vs. injection
Glutathione is a compound of three amino acids, and is a protein with a very large molecular size. The problem is that because of its size, it is difficult to absorb by oral intake. In addition, the absorption rate of oral nutrients is low because the active ingredient is decomposed during the digestive process when taken.
On the other hand, intravenous injection has a high absorption rate because it is delivered directly into the bloodstream. The injection is originally an injection to improve liver function in patients with chronic liver disease, and is administered 100 to 200 mg once a day. In addition, it is also administered to prevent neurological diseases that may occur when administering anticancer drugs to cancer patients. Therefore, excessive use of the injection for cosmetic purposes should be avoided.
