But, glutathione has become more popular due to its fastest skin lightening action and also, because of wide social media coverage.
Glutathione is a peptide derived from three amino acids glutamate, cysteine and glycine. It is a known antioxidant and detoxifies xenobiotics. Its skin lightening effect was detected incidentally. Skin lightening was noticed in a patient as a side effect of large doses of glutathione, which was given for some other disease and then onwards, it has become more popular as a skin lightening agent.
Tyrosinase is an enzyme, which helps in melanin synthesis (melanin is a pigment, which decides color of skin). Glutathione inhibits this enzyme, so less melanin is produced and skin becomes light. Besides this, it also switches production of eumelanin (produce dark brown color) to pheomelanin (produce yellow-red color), which leads to lightening of skin.
Natural sources like tomato, orange, walnuts, whey protein, fresh fruits and green leafy vegetables are rich in glutathione.
Various formulations like topical, oral and injectable forms are available.
For local application like face wash cream, chemical peels containing glutathione are available. Use of these products show significant improvement in skin complexion.
Oral preparations like tablet and solution forms are also available. The tablet if taken sublingual the absorption will be better and requires lower doses.

The effects become visible within four weeks and the significant effects may need maximum three months. Depending on the skin color, like medium brown skin requires one to three months and dark skin requires more than 2 years of treatment. After attaining desired skin color, maintenance dose of 500 mg per day for a longer duration is suggested
The intravenous dose recommended is 600 -1200 mg once or twice in a week, but various adverse effects are reported with the intravenous route due to the possibilities of overdose toxicities or may be due to additives present in glutathione injections.
