⭐ How Glutathione Works (Science Explained Simply)

Glutathione brightens the skin by:

1. Reducing Melanin Production

Melanin is the pigment responsible for dark skin tone and pigmentation.
Glutathione blocks the tyrosinase enzyme, the main trigger for melanin creation.

Less melanin =
✔ Brighter skin
✔ Reduced pigmentation
✔ Even tone

For whitening-focused results, see Glutathione for Skin Whitening.

2. Switching Dark Melanin to Light Melanin

The skin produces two forms of melanin:

  • Eumelanin → dark, deep pigmentation
  • Pheomelanin → light, fair pigmentation

Glutathione shifts the balance toward pheomelanin, creating a naturally lighter appearance. For targeted pigmentation correction, visit Glutathione for Dark Spots.

3. Repairing Sun Damage

UV rays increase oxidative stress in the skin.
Glutathione neutralizes these free radicals, protecting skin cells from:

  • Sun damage
  • Tanning
  • Dark patches
  • Premature aging

4. Enhancing Skin Clarity & Glow

By improving cellular repair and detoxification, Glutathione improves:

✔ Skin clarity
✔ Freshness

This gives the skin a more youthful, radiant appearance.
