DEPIGMENTATION Properties of Glutathione/Selenium

• Protect Skin from UV Radiation which generate free radicals that cause skin damage and hyperpigmentation

• GSH redirects synthesis to the light (Pheomelanin) instead of the dark (Eumelanin)

• Inhibits enzyme tyrosinase that synthesizes dark melanins

• Skin Cell’s become more resistant to UV exposure (Brigarti, 2003)

(Burke, 1997)

Influence of Glutathione Levels in Melanin Synthesis

Pathways to Melanin Synthesis

High GSH Low GSH

↓ Eumelanin Eumelanin

(Dark Pigment) (Dark Pigment)

Conclusion:

High GSH levels influence pathway toward the production of greater amounts of clear pigment (Pheomelanin) in skin cells
