In skincare, glutathione has emerged as a significant brightening ingredient because of its multi-pathway melanin inhibition: it inhibits tyrosinase (reducing melanin synthesis), shifts melanogenesis from darker eumelanin towards lighter phaeomelanin (changing the type of melanin produced), and scavenges the free radicals and reactive oxygen species that trigger melanocyte melanin overproduction (addressing the upstream trigger of pigmentation)
L-Carnitine shuttles essential fatty acids into the mitochondria, the energy source of the cell, where they can be turned into fuel
