medicube AGE-R Glutathione Glow Serum — 50,000 ppm Brightening, Anti-Aging Hydration

Medicube AGE-R Glutathione Glow Serum is a daily antioxidant and elasticity serum formulated with high-concentration glutathione and skin-firming actives to brighten pigmentation and restore youthful bounce.

This lightweight serum blends potent brighteners with collagen-supporting ingredients to target spots, uneven tone, and fine lines while leaving skin hydrated and luminous. Designed for daily use and optimized to work with Booster-H for improved absorption, the formula focuses on long-lasting radiance without harsh irritation. Clinical-style testing for low irritation supports its use in gentle routines.

How does this serum improve skin tone and reduce pigmentation?

The AGE-R serum concentrates glutathione alongside niacinamide and Bifida ferment lysate to address discoloration and dullness. These ingredients help regulate visible melanin effects and encourage a more even, reflective complexion over continued use.

• 50,000 ppm glutathione for antioxidant brightening support
• Niacinamide to even tone and reduce the appearance of spots
• Bifida ferment lysate to strengthen skin barrier and assist renewal
• Patented skin-like collagen to plump texture and soften lines

Will this serum help with fine lines and loss of firmness?

Yes — the formula pairs adenosine and collagen-mimicking peptides to visibly smooth expression lines and add volume to flattening areas. Regular nightly or twice-daily application can make lines appear softer while improving skin resilience.

• Adenosine to support visible wrinkle reduction
• Skin-like collagen to add surface plumpness and elasticity
• Hydrating base to maintain a supple, restored appearance

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

For best results, apply AGE-R Glutathione Glow Serum after cleansing and toning, before thicker creams. Using it with Booster-H increases its delivery and efficacy, making active ingredients more available to the skin.

• Cleanse and tone, then dispense 1–2 pumps of AGE-R serum
• Follow with Booster-H to amplify absorption (serum is 3x more effective with Booster-H)
• Seal with moisturizer and sunscreen in the morning

Is the serum gentle enough for daily use and sensitive skin?

The formulation balances potent actives with a hydration-focused base and has undergone primary patch testing for low irritation. While designed for daily application, those with reactive skin should patch-test first and introduce slowly.

• Low-irritation profile from primary patch testing
• Hydra-friendly viscosity that doesn’t strip moisture
• Suitable for layering in multi-step Korean-style routines

Who is this for? Medicube AGE-R Glutathione Glow Serum is for anyone seeking a daily brightening and elasticity treatment that targets uneven tone, early expression lines, and loss of radiance. It suits those who prefer lightweight, antioxidant-forward serums and people who want to pair a targeted treatment with a booster for improved delivery. If you want a non-drying, easily layered product to enhance glow and surface form, this serum fits into morning and evening regimens; sensitive users should patch-test before full application.
