How does Glutathione work?

Competitively inhibits melanin synthesis in the reaction of tyrosinase and L-DOPA by interrupting L-DOPA's ability to bind to tyrosinase during melanin synthesis. These results indicate that glutathione inhibits the synthesis and agglutination of melanin by interrupting the function of L-DOPA.It is the master anti-oxidant that helps fight free radicals that causes skin damages. It also contributes to good liver function. Our clinical studies showed that Glutathione works best with the combination of Vitamin C and Collagen.
