medicube AGE-R Glutathione Glow Serum — Brightening & Elasticity with 50,000 ppm Glutathione for Dewy Skin

Medicube AGE-R Glutathione Glow Serum is a daily antioxidant and elasticity serum formulated to brighten, improve texture, and promote a dewy Korean glass-skin finish.

This serum blends a high-concentration glutathione complex with niacinamide, adenosine, patented skin-like collagen and bifida ferment lysate to target dullness, pigmentation signs, and early expression lines while keeping skin hydrated and comfortable. Its medium viscosity sits well under creams or layers and is designed to pair with Booster-H for improved absorption and amplified effects.

How does this serum help uneven tone and pigmentation?

The AGE-R formula focuses on ingredients that support a more luminous, even complexion. Glutathione at high concentration helps reduce the appearance of discoloration while niacinamide assists with tone uniformity and skin clarity.

• 50,000 ppm glutathione-rich Active Glow-zom Technology to target dark spots.
• Niacinamide to brighten and refine surface texture.
• Bifida ferment lysate to support recovery and resilience.

Will this serum improve firmness and visible lines?

The serum combines elasticity-supporting ingredients that create a plumping, smoother appearance. Patented skin-like collagen and adenosine work together to help skin look fuller and reduce the visibility of fine lines when used consistently.

• Patented skin-like collagen provides a cushiony, volumizing feel.
• Adenosine to support temporary smoothing of expression lines.
• Hydrating base to maintain skin suppleness throughout the day.

How should I use AGE-R Glutathione Glow Serum in my routine?

Apply the serum after cleansing and toning, before heavier creams or sunscreen. For best results, combine with Booster-H to increase penetration; the brand states the serum performs up to three times better alongside the booster.

• Use 1–2 pumps morning and night on clean skin.
• Layer under moisturizer and sunscreen for daytime protection.
• Pair with Booster-H to enhance absorption and efficacy.

Is this serum suitable for sensitive skin and everyday use?

AGE-R is formulated to be gentle while remaining effective: it has passed a primary patch test indicating low irritation potential. As with any active product, introduce it gradually and monitor for reactions when combining with other actives.

• Primary patch-test completed with low irritation results.
• Designed for daily application morning and night.
• Avoid concurrent use with highly exfoliating acids without professional guidance.

Who is this for: Medicube AGE-R Glutathione Glow Serum is aimed at people seeking brighter, more even-toned skin with improved elasticity and a dewy finish. It suits users who want a daily, non-drying serum that plays well with layered routines and those who plan to use a targeted booster like Booster-H for stronger results. If you want a K-beauty style glow with ingredients focused on radiance and texture rather than harsh peels, this serum is a practical addition to your regimen.
