Glutathione (GSH) is a very magical whitening ingredient. It plays an important role in the biochemical defense system of the human body and has many physiological functions. Its main physiological role is to remove free radicals in the human body, as an important antioxidant in the body, to protect many proteins and enzymes.

The structure of GSH contains an active sulfhydryl -SH, which is easily dehydrogenated by oxidation, and this specific structure makes it the main free radical scavenger in the body. For example, when a small amount of H2O2 is produced in the cell, GSH reduces H2O2 to H2O under the action of glutathione peroxidase, and itself is oxidized to GSSG, which receives H to be reduced to GSH under the action of glutathione reductase present in the liver and red blood cells, so that the free radical scavenging reaction in the body can be continued. Glutathione can not only eliminate free radicals in the human body, but also improve human immunity. Glutathione is healthy and anti-aging, and has a greater effect on the cells that slow down in older people than in younger ones.

Glutathione can also protect hemoglobin from hydrogen peroxide oxidation, free radicals and other oxidation, so that it can continue to perform normal oxygen transport capacity. Part of the hemoglobin in the red blood cells under the action of oxidizing agents such as hydrogen peroxide, in which the bivalent iron is oxidized to trivalent iron, so that the hemoglobin is transformed into methemoglobin, thus losing the oxygen carrying capacity. Reduced glutathione can not only directly combine with oxidizing agents such as hydrogen peroxide to form water and oxidized glutathione, but also reduce methemoglobin to hemoglobin.

Glutathione, when used in combination with vitamin C, can improve its efficacy. To this end, glutathione can restore a woman's pearl-like white skin, and can fade stubborn spots, remove wrinkles, increase skin elasticity, shrink pores, fade pigment, whole body whitening has an excellent effect.
