Glutathione is one of the largest endogenous anti-oxidants produced by cells. Four main functions stand out: anti-melanogenic, anti-oxidant, detoxifier and reinforcer of the immune system. It shows an action that inhibits melanin synthesis thanks to its competitive action with L-DOPA in its binding to tyrosinase during melanin synthesis. Due to its strong anti-oxidant action, it acts directly in the neutralisation of free radicals and reactive oxygen compounds, as well as for maintaining exogenous anti-oxidants such as vitamins C and E. This actions gives it a high detoxifying power of harmful endogenous substances.
