Poor Skin Penetration: As a hydrophilic molecule, naked glutathione cannot effectively penetrate the lipid-rich barrier of the stratum corneum
In IC, TGF- fails to effectively mediate tissue regeneration, leading to fibroblast activation and fibrosis, which further inhibits cell proliferation (Mormone et al., 2024)
When glutathione levels are healthy, it helps neutralize this oxidative stress and calms the inflammatory response
Understanding these mechanisms helps explain why this peptide has attracted significant research interest for anti-aging applications
