Reduced Glutathione (GSH) Powder

Why Use Reduced Glutathione?

Reduced Glutathione (GSH) helps restore balance to stressed or aging skin by reducing oxidative stress, detoxifying cells, and promoting radiance. It is widely used in skin-brightening treatments and anti-aging formulas thanks to its ability to inhibit melanin synthesis and improve skin luminosity.

Key Benefits:

• Potent antioxidant that fights free radical damage
• Supports skin brightening and helps reduce hyperpigmentation
• Boosts skin radiance and evens out complexion
• Helps regenerate other antioxidants like Vitamin C and Vitamin E
• Protects skin cells against oxidative stress and aging

Common Applications:

• Brightening serums
• Anti-aging creams
• Sheet masks and treatments
• Post-procedure recovery formulations

Usage Guidelines:

• Use at 0.1% – 2% depending on formulation type
• Add during the cool-down phase to avoid heat degradation
• Formulate at pH 4.5 – 7.0 for best stability
• Always use chelators (e.g. EDTA, phytic acid) to protect against metal-catalyzed oxidation
• Combine with synergistic antioxidants (Vitamin C, Niacinamide, Ferulic Acid) for enhanced brightening and protection

Important Product Info:

• For cosmetic use only
• Reduced Glutathione is inherently unstable in water-based formulations and requires stabilization
• Protect from air, light, and humidity to minimize oxidation
• Store in a tightly sealed, opaque container in a cool, dry place
• Color change (yellowing/browning) can occur if improperly stored or exposed to oxygen

Formulation Tips:

• Best used in formulations with additional stabilizers (ascorbic acid, ferulic acid, or liposomal encapsulation)
• Pairs well with hyaluronic acid serums for hydration + brightening effects
• Airless pumps can help extend shelf life
