Glutathione — the body's master antioxidant, used topically for brightening and antioxidant support. Safe on skin; topical effectiveness depends on stable delivery systems.

Skin benefits

  • Tripeptide naturally found in skin
  • Well-tolerated topically

Known concerns

  • Stability is poor without specialised delivery
  • Most strong evidence is for IV/oral use, not topical
