This is largely due to the presence of l-glutathione, a compound known to inhibit melanin production which causes darkening of the skin
Branched-Chain Amino Acids The role of branched-chain amino acids (BCAAs), which include leucine (ketogenic), isoleucine, and valine (glucogenic ones), in tumor biology and immune responses is being described in different studies (Table 7)

Retinol's nuclear receptor mechanism and epidermal cell turnover
Intrinsically, recent large-scale cohorts reveal that disease risk and drug responses are deeply rooted in strain-level variations, such as within-species phylogenetic diversity and strain-specific gene carriage [67]
Because glutathione works by inhibiting melanin production at the source, it's considered one of the more effective non-invasive options for gradually improving melasma and hyperpigmentation over time
