Key Mechanism for Skin Whitening: Glutathione inhibits the enzyme tyrosinase, which plays a role in melanin production

Oxythiamine and dehydroepiandrosterone inhibit the nonoxidative synthesis of ribose and tumor cell proliferation

While glutathione is a powerful antioxidant and theoretically could reduce oxidative stress in melanocytes, there is no robust clinical data showing that increasing dietary or supplemental glutathione can reliably prevent or reverse gray hair in humans. The bodys regulation of hair pigmentation is complex, he added, and once melanocytes lose their ability to produce pigment, antioxidants alone are unlikely to restore it
