Glutathione is a versatile skincare ingredient suitable for most skin types, particularly those with hyperpigmentation, uneven skin tone, or signs of ageing
Upon its efflux from cells, oxidised glutathione is exposed to the sequential action of enzymes located on the external face of the cell membrane: -glutamyl transpeptidase (GGT) generates glutamate 94 and the cysteinylglycine dipeptide, which is degraded by dipeptidases such as aminopeptidase N (APN), thereby releasing cysteine and glycine
