Glutathione- Summary
- Matrixyl is the most widely used collagen-stimulating cosmetic peptide. As a matrikine — a fragment of type I procollagen — it signals skin cells to synthesize new collagen, elastin, and fibronectin, reducing wrinkle depth and improving skin firmness and elasticity.
- Glutathione is the body's master endogenous antioxidant tripeptide, composed of glutamate, cysteine, and glycine. It neutralizes reactive oxygen species, supports detoxification in the liver, recycles other antioxidants (vitamins C and E), and plays a central role in immune function, DNA repair, and cellular redox balance.
- Half-Life
- N/A — topical; sustained signaling effects on fibroblasts persist beyond single application
- Minutes to hours depending on route; IV half-life approximately 10-30 minutes
- Admin Route
- Topical
- Oral (liposomal preferred), Sublingual, Intravenous, Nebulized/inhaled, Topical
