Glutathione is composed of glutamic acid, cysteine, and glycine. It is a tripeptide containing a sulfhydryl group, referred to as GSH, which is the collective name of glutathione Glutathione + sulfhydryl SH. Glutathione plays a central role in clinical detoxification, so it plays a significant role in purifying internal organs.


Glutathione has the effect of whitening and improving skin quality.


The cysteine in glutathione can reduce the activity of tyrosinase. Cysteine is an amino acid containing a sulfhydryl group. The sulfhydryl group has a strong nucleophilic effect. The thiol group can quickly react with dopaquinone to quickly form a colorless dopa derivative, thereby blocking the transformation of dopa into a pigment.


Glutathione interferes with the synthesis of melanin, and its mechanism mainly includes:

1. Directly inhibit the activity of tyrosinase.

2. Free radicals can activate tyrosinase, and glutathione can scavenge free radicals and inhibit the activation of tyrosinase.

3. Make the melanin synthesis pathway lean towards pheomelanin (rather than the melanin that darkens the skin).


To prevent skin aging and poor skin quality, the first task is to have a reasonable work and rest time, a healthy lifestyle, and supplement the body's necessary antioxidants to scavenge free radicals. The biggest external cause of skin darkening and aggravation of spots is still sunlight, so sun protection is the primary task of maintaining fair and flawless skin, followed by inhibiting the action of tyrosinase through scientific means, or reducing or blocking the already produced Melanin is some of the methods of modern science to whiten the skin.
