Scientific basis for brightening formulations From a formulation perspective, glutathione works synergistically with other brightening agents such as vitamin C, niacinamide, and tranexamic acid to build multipathway whitening systems
The first group function in glutathione homeostasis including amino acid uptake transporters (SLC7A11 and SLC6A9), GSH synthesizing enzymes (-GCLc and -GCLm), GSH metabolizing enzymes that eliminate ROS through GSSG/GSH oxidation-reduction cycle (GPx and GRx) and GSH complementary enzymes such as glutathione transferases (GST)
