L-Reduced Glutathione (GSH) is a naturally occurring tripeptide (L-cysteine, L-glutamic acid, and glycine) and the body’s “Master Antioxidant”. It is critical for cellular defense, detoxification, and immune function. Topically, GSH delivers powerful skin-lightening, anti-aging, and detoxification benefits by directly neutralizing free radicals and significantly shifting the melanin production pathway from dark (eumelanin) to light (pheomelanin) pigment.
| INCI Name | Glutathione |

| Appearance | White crystalline powder |
| Core Function | Skin Brightening, Master Antioxidant, Detoxification, Anti-aging, Tyrosinase Inhibition. |
Clinically proven to reduce skin sensitivity markers by 40% within 48 hours, while actively inhibiting tyrosinase to shift pigment production toward lighter pheomelanin and providing profound cellular detoxification against oxidative damage.
In the advanced landscape of clinical skin brightening and cellular detoxification, delivering the unparalleled “Master Antioxidant” efficacy without triggering surface irritation or rapid oxidation is the ultimate formulation challenge. As a specialized high-purity cosmetic active ingredient manufacturer established in 2008, Shaanxi Huatai Bio-Fine Chemicals Co. delivers a premium L-Reduced Glutathione (GSH) rigorously engineered to completely remove residual impurities. Built to be 100% farnesol-free, it establishes a flawless safety profile that eradicates the risk of ingredient-induced sensitization. By functioning exclusively in its biologically active reduced form, this ultra-pure tripeptide provides comprehensive cellular defense, recycles endogenous antioxidants, and delivers clinical-level brightening for even the most hyper-reactive and sensitive skin.
For Global OEM/ODM Innovators: Achieve ultimate formulation elegance and extreme compatibility. Our highly purified L-Reduced Glutathione dissolves flawlessly into the aqueous phase, engineered to yield a highly refined, crystal-clear, water-white, and entirely odorless profile in your final delivery systems. It ensures zero unintended formula discoloration and guarantees it will never compromise the precise color, fragrance, transparency, or aesthetic of your final brightening serums or detoxification masks. Exceptionally pure, it eliminates the manufacturing friction typically associated with highly sensitive antioxidants when paired with standard cold processing and stabilizing agents for your R&D teams.
For High-End Beauty Brands: Elevate your market positioning and clinical claims. This ultra-pure, master antioxidant active is the signature choice for strict “Clean Beauty” mandates and highly tolerable “SOS Emergency Repair” formulations. Empower your brand to market “Cellular Detoxification,” “Melanin Modulation,” and intense free radical neutralization without the irritation linked to harsh chemical skin lighteners. Capture the fierce loyalty of consumers demanding highly potent, non-sensitizing clinical solutions that deliver flawless luminosity, profound cellular repair, and intense tissue calming.
Appearance: High-purity white powder (yields a refined, clear, and water-white profile when properly dissolved in aqueous cosmetic solutions)
Odor: Odorless (scent neutral for absolute formulation control)
Purity: ≥ 98.0% (Biologically active L-Reduced Form for maximum tyrosinase inhibition and detoxification)
Molecular Weight: 307.32 g/mol
Heavy Metals: < 10 ppm
Recommended Dosage: 0.5% – 2.0% (Highly potent for daily defense and intensive spot reduction)
pH Range Stability: Best maintained within an optimal slightly acidic pH of 5.0 – 6.0
Processing Guidelines: Highly water-soluble. Must be incorporated into the aqueous phase during the cooling process (below 40°C) to prevent conversion to the inactive GSSG form. Formulate in a low-oxygen environment and utilize stabilizing agents (such as EDTA) and synergistic co-antioxidants (like Vitamin C) to ensure maximum shelf-life and active efficacy.
Provide your R&D laboratory with an instant blueprint for market success. Our L-Reduced Glutathione acts as a supreme biological defense engine, protecting and amplifying the restorative efficacy of companion actives:
L-Reduced Glutathione + Allantoin: The ultimate post-blemish clearing and cellular soothing matrix. Combines the active melanin modulation and free radical neutralization of Glutathione with the water-soluble wound-healing properties of Allantoin to rapidly fade post-inflammatory hyperpigmentation, clear micro-traumas, and instantly soothe hyper-reactive skin.
L-Reduced Glutathione + Panthenol: A comprehensive “SOS Barrier Rescue” and defensive detox system. Panthenol floods the stratum corneum with deep, targeted hydration, creating a healthy, non-reactive environment that allows Glutathione to effectively act as a co-factor for detoxification enzymes and neutralize environmental toxins without triggering tightness or reactivity.
L-Reduced Glutathione + Ceramide NP: The absolute structural longevity and “Clean Beauty Brightening” complex. While L-Reduced Glutathione works fundamentally from within the cells to shift melanogenesis and protect fibroblasts from oxidative apoptosis, Ceramide NP safely and physically rebuilds the skin’s depleted lipid cement on the surface, ensuring a resilient, luminous, and perfectly defended skin barrier.
