medicube AGE-R Glutathione Glow Serum — 50,000ppm brightening serum, hydrating dewy finish

AGE-R Glutathione Glow Serum is a lightweight brightening and elasticity serum that uses a high-concentration glutathione complex to refresh dull, pigmented skin and boost visible radiance.

This serum from medicube blends potent brightening actives with skin-supporting ingredients to target uneven tone, spots, and early expression lines while preserving a hydrated, dewy finish. Formulated with a skin-friendly viscosity designed for compatibility with the Booster-H applicator, the formula layers easily under moisturizers and helps skin appear smoother and more luminous without feeling tight.

How does AGE-R Glutathione Glow Serum brighten pigmentation and spots?

The serum combines glutathione at a concentrated level with niacinamide and fermentation-derived ingredients to help even skin tone over time. These components act on surface discoloration and support the look of clearer, more uniform skin when used consistently.

• 50,000ppm glutathione complex to target dullness and pigmentation.
• Niacinamide for brightening and barrier support.
• Bifida fermentation lysate to help skin recovery and resilience.
• Daily use recommended for progressive improvement.

What immediate texture and finish can I expect when applying it?

The serum has a medium-light viscosity formulated to spread smoothly and leave a hydrated, subtle glow rather than a matte or sticky finish. It’s intended to be used with or without Booster-H, but pairs especially well with the Booster-H delivery system for enhanced absorption.

• Hydra-coated feel that maintains skin moisture.
• Non-drying, non-greasy finish suitable under makeup.
• Designed to layer under creams and sunscreens without pilling.

Will this serum help reduce the look of fine lines and texture?

The AGE-R formula includes patent-backed collagen-like molecules and adenosine to target the appearance of expression lines and support smoother texture. While results vary by individual, regular use can help plump and soften the look of fine lines for a more voluminous appearance.

• Adenosine helps manage visible expression lines with consistent application.
• Patented skin-like collagen-mimetic ingredient supports firmness and bounce.
• Formulated to fill and smooth areas like crow’s feet and smile lines.

How should I use it with Booster-H and other skincare steps?

Apply AGE-R Glutathione Glow Serum after cleansing and toning, then follow with Booster-H to enhance penetration and efficacy. Finish with moisturizer and sunscreen in the morning; at night, layer with richer creams if needed for extra hydration.

• Use 1–2 pumps of serum on clean skin, morning and evening.
• Pair with Booster-H for up to 3x improved absorption and results.
• Seal with moisturizer and daytime SPF for protection and optimal effect.

Who is this for? AGE-R Glutathione Glow Serum suits anyone looking to address uneven tone, sunspots, and the early signs of aging while maintaining a dewy, hydrated finish. It’s a practical choice for skin types seeking brightening without harsh drying, and for users who want a serum engineered to work with Booster-H for intensified delivery.
