Unlike many other antioxidants, glutathione works inside the cells, giving them unique detoxifying abilities
It works by: Preventing melanin production (skin darkening) Fighting oxidative stress Detoxifying the liver Neutralizing UV-induced damage Improving skin brightness and smoothness This means timing can influence how efficiently your body uses itand when its most needed
At the same time, although excitatory amino acids have no obvious effect, there is a decreasing trend, which can inhibit the expression of excitatory amino acid receptors, thereby weakening excitatory signal transduction and ultimately alleviating neurotoxicity

One clinical study has also shown the benefits of oral administration of glutathione
