Results from glutathione use can vary between individuals
The majority (90%) of the APAP is funneled into phase II metabolic pathways, in which APAP conjugation is catalyzed by UDP-glucuronosyl transferases (UGT) and sulfotransferase (SULT), with conversion to glucouronidated and sulfated metabolites that are eliminated from the body in the urine 8 (Figure 1)
They also modulate the action of antioxidant enzymes
Glutathione is one of the most extensively characterized intracellular antioxidant molecules in biochemistry, present at millimolar concentrations in most mammalian cells
however, it may not be applicable to all skin types, conditions, or sensitivities
Hyaluronic acid: keeps the skin moisturized and plump, enhancing absorption For faster results, the majority of brightening serums now combine glutathione with supportive active ingredients
