Core redox chemistry and enzymatic cycles Peroxide reduction and recycling: Selenium-dependent glutathione peroxidases (GPx) reduce H2O2 and lipid hydroperoxides using two GSH, forming GSSG; glutathione reductase (GR) then reduces GSSG back to GSH using NADPH, sustaining the cellular reducing environment (GS–SG + NADPH + H+ → 2 GSH + NADP+).

Evidence by indication and route Dermatologic skin lightening/melasma • Topical and oral: Several small randomized, placebo-controlled trials report reductions in melanin index and improvements in skin properties over 8–12 weeks, with mostly mild adverse events; however, trials are small, short, and use varied formulations and endpoints.

Receptor interactions Calcium-sensing receptor (CaSR): Emerging evidence indicates circulating “glutathionergic” species can bind extracellular sites on CaSR and modulate receptor activity, suggesting a receptor-mediated complement to redox functions; while mechanistic models have been proposed, this remains less established than intracellular redox signaling and should be interpreted with caution.

A meta-analytic summary of systemic GSH indicates variable dose–response and inconsistent biomarker effects, complicating mechanistic attribution. • IV cosmetic use: No long-term safety studies; regulatory warnings cite risks including hepatotoxicity, severe allergic reactions, and lack of standardized dosing; reports of serious adverse events such as anaphylaxis exist.

Key limitations, gaps, and criticisms • Bioavailability and measurement: Inconsistent increases in circulating GSH with supplementation; marked heterogeneity in assays and compartments measured; unclear translation of PBMC or local tissue changes to clinical outcomes. • Small, short, and heterogeneous trials: Most studies enroll tens of participants over weeks, with varied dosing, routes, and endpoints; meta-analyses are hampered by heterogeneity and selective reporting. • Lack of definitive outcomes: Many studies focus on surrogate biomarkers (GSH/GSSG, oxidative stress markers) rather than clinically meaningful endpoints; where clinical endpoints are used (e.g., CIPN severity, skin lightening), findings are mixed and often context-specific. • Safety concerns for IV cosmetic use: Regulatory advisories and reports of serious adverse events, without long-term safety data or standardized dosing, drive strong criticism of IV GSH for skin lightening. • Comparative effectiveness unknown: Few head-to-head trials comparing GSH formulations (oral vs liposomal vs IV) or GSH vs precursors (NAC, GlyNAC) on both biomarkers and clinical outcomes. • Neurologic and infectious indications: Feasibility/biomarker signals exist (e.g., intranasal CNS uptake; liposomal GSH immune effects), but robust efficacy RCT
