High Stability and Bioavailable Glutathione, Natural Whitening Active Ingredient

1. Product Description

• Glutathione (GSH) is a high-activity endogenous tripeptide active substance naturally present in human cells, composed of glutamic acid, cysteine and glycine. As a core cellular antioxidant and skin metabolic regulator, it features ultra-high human homology and excellent skin biocompatibility, with mild properties and zero irritation. Different from traditional single whitening ingredients, glutathione integrates antioxidant protection, melanin metabolism regulation and cellular anti-aging repair, focusing on solving skin dull yellowing, pigmentation, oxidative aging and poor skin vitality caused by free radical damage and metabolic disorders. Adopting advanced biological fermentation and multi-stage purification technology, the finished raw material boasts high purity, high bioactivity and stable molecular properties, which is widely used in high-end whitening brightening, antioxidant anti-aging and functional skincare formula development.

2. Core Efficacy

• Powerful Antioxidant & Anti-Aging: Efficiently scavenges excess free radicals in skin cells, blocks lipid peroxidation reaction, reduces oxidative damage to skin tissues, delays cellular senescence process, improves skin relaxation and dull aging state, and maintains youthful skin vitality.
• Inhibit Melanin & Brighten Skin Tone: Effectively inhibits tyrosinase activity, cuts off melanin synthesis and deposition pathway, reduces abnormal pigment production, fades superficial pigmentation and yellowish dullness, and uniformly brightens overall skin tone for translucent complexion.
• Optimize Skin Metabolism & Dullness Improvement: Accelerates the metabolic decomposition and excretion of skin aging waste, residual pigments and dull substances, improves sluggish basal metabolism, refreshes tired and dull skin, and restores skin gloss and clarity.
• Repair Oxidative Damaged Skin: Participates in cellular protein synthesis and skin tissue repair, improves cell vitality decline caused by oxidative damage, enhances skin self-repair ability, and relieves dry and rough skin texture caused by external stimulation.
• Enhance Skin Defense Capability: Activates skin endogenous antioxidant system, improves skin resistance to external ultraviolet radiation, environmental pollution and oxidative stimulation, and reduces frequent skin dullness and aging problems.

3. Production Process

• High-Quality Biological Raw Material Screening: Select high-grade food and cosmetic-grade amino acid raw materials with high activity and low impurity, strictly screen raw material purity, microbial indicators and activity stability, eliminate unqualified raw materials to ensure pure and high-quality production foundation.
• Precision Biological Fermentation Synthesis: Adopt controlled constant-temperature microbial fermentation technology, simulate human endogenous synthesis pathway, induce directional synthesis of glutathione active molecules, retain natural biological activity and complete molecular structure, and avoid chemical synthesis residual risks.
• Multi-Stage Membrane Purification & Impurity Removal: Through high-speed centrifugation, multi-layer ultrafiltration membrane interception and molecular sieve classification technology, thoroughly remove fermentation residues, invalid macromolecular impurities and heterologous substances to improve raw material purity.
• Low-Temperature Activity Locking Treatment: Adopt low-temperature vacuum drying and molecular stabilization technology, effectively prevent glutathione molecular oxidation and activity attenuation, lock high biological activity, and ensure long-term stable efficacy of raw materials.
• Aseptic Finishing & Strict Batch Inspection: Complete refining, drying and sealed packaging in dust-free sterile workshop. Each batch passes strict HPLC purity detection, activity analysis and microbial safety inspection to meet high-end cosmetic-grade application standards.
