Medicube [EUP] AGE-R GLUTATHIONE GLOW SERUM 30g

Glutathione is a naturally occurring antioxidant composed of amino acids, widely recognised in skincare for its role in promoting a more even, luminous-looking complexion. In the AGE-R Glutathione Glow Serum, it is present at a concentrated 500ppm dose, working in synergy with Niacinamide and Active Glow-zom Technology to visibly address dullness and uneven skin tone with continued use.

No, the AGE-R Glutathione Glow Serum can be used as a standalone product in your daily skincare routine and will deliver brightening and hydrating benefits on its own. However, clinical data indicates that results are significantly amplified when used in combination with the Medicube AGE-R Booster-H device — with glow enhancement reaching up to 9.9% improvement compared to 3.5% with the serum alone.

Yes. The AGE-R Glutathione Glow Serum has undergone a Primary Patch Test and has been assessed as low-irritating, making it suitable for daily use on most skin types, including sensitive skin. As with any new skincare product, we recommend performing a patch test on a small area of skin before full application.

For optimal results, the serum is designed for twice-daily use — once in the morning and once in the evening. Consistent use over a minimum of four weeks is recommended to observe visible improvements in radiance, blemish reduction, and overall skin luminosity, as supported by clinical study data.

Alongside 500ppm Glutathione, the serum features a comprehensive brightening and anti-ageing complex including Niacinamide (to support an even skin tone), Adenosine (to help address the appearance of fine lines), Bifida Ferment Lysate (a probiotic-derived ingredient for skin resilience), Patented Skin-Like Soluble Collagen, multi-weight Hyaluronic Acid (for deep and surface-level hydration), Ceramide NP (to support the skin barrier), Squalane, Beta-Glucan, and Panthenol.

On average, one bottle of the Age-R Glutathione Glow Serum (50ml) lasts approximately 1 to 2 months with consistent daily use.


The exact duration may vary depending on your personal application habits:


DAILY USE: If applied once or twice daily (morning and night) as part of your regular skincare routine, it typically covers a 4 to 6-week period.


USAGE AMOUNT: A small amount of this high-performance formula is sufficient to enhance your skin's natural radiance and provide a luminous, healthy-looking glow.


SHELF LIFE: To ensure optimal freshness and efficacy of the glutathione and vitamin-rich formula, we recommend using the product within 12 months after opening (please refer to the PAO symbol on the packaging).
