Glutathione is composed of glutamic acid, cysteine and glycine. It contains sulfhydryl group. It has the function of anti-oxidation and integrated detoxification, therefore it can transform the harmful poisons into harmless substances and excrete them out of the body. Glutathione also helps maintain normal immune system function. There is the use in the whitening needle, which can whiten the skin through metabolism of toxins.

Glutathione has high purity and good water solubility. Glutathione is a kind of active polypeptide, which has important physiological functions. Its molecular structure contains a sparsely radical structure, so it has the biological activity of scavenging free radicals. Therefore, Glutathione is widely used in cosmetics, medicine, health products and other industries.
