Medicube AGE-R Glutathione Glow Serum – 50ml

Overview

Medicube Glutathione Glow Serum is a radiance-boosting, tone-support serum designed to help skin look brighter, smoother, and more “glowy” with consistent use. It’s formulated with a high level of Glutathione (50,000ppm) alongside glow-support partners like Niacinamide and Adenosine, plus skin-conditioning ingredients often used for bounce and barrier comfort (such as collagen-related components and ferments).

Available in 30ml and 50ml, this serum fits both lifestyles: the 30ml is great for first-time users and travel, while the 50ml is ideal for daily AM/PM routines. The texture is lightweight and layer-friendly, so it sits comfortably under moisturizer and sunscreen—especially useful in humid weather and busy “commute-to-office” days when you want glow without heaviness.

Key benefits

• Glow & radiance: helps reduce the look of dullness and supports a brighter-looking complexion
• Uneven tone care: supports a more even-looking skin tone and helps improve the appearance of spots over time
• Elastic-look support: helps skin appear more bouncy and refined with consistent use
• Hydration + smooth feel: helps soften rough texture so skin feels more supple
• Routine-friendly: lightweight finish that layers well under sunscreen and makeup

Who it’s for

This serum is ideal for all skin types—especially if your main concerns are dullness, uneven tone, post-blemish marks, or a lack of “fresh glow.” It’s also a great option if you want brightening care but prefer a serum that still feels hydrating and comfortable. If you have very sensitive skin, patch test first and introduce it gradually.

How it works

Glutathione + Niacinamide for glow-focused tone support

Glutathione is included as a key antioxidant-style brightening ingredient (Medicube highlights 50,000ppm), while niacinamide supports a clearer-looking tone and a smoother overall appearance. Together, they target the “dull + uneven” look that often shows up from sun exposure, stress, and post-breakout marks.

Adenosine + supportive conditioning for a smoother finish

Adenosine is commonly used in K-beauty for line and elasticity-look care, helping skin appear more refined. The formula also includes supportive ingredients (like collagen-related components and ferments) to keep the finish comfortable so you can stay consistent—because consistent use is what brings the best visible improvement.

How to use

• After cleansing and toner, apply 2–3 drops to the face and neck.
• Gently pat until absorbed, then follow with a moisturizer.
• Use morning and night. In the morning, finish with sunscreen.

Pro tip: Medicube often pairs AGE-R serums with their devices (like Booster-H). If you use a device, apply the serum as directed by the device routine; otherwise, it works perfectly as a normal daily serum.

Why customers love it

Customers love Medicube Glutathione Glow Serum because it delivers a “clean glow” look without feeling heavy. It absorbs easily, layers well, and fits into simple routines—toner → serum → moisturizer → sunscreen—making it realistic to use every day. Many people also appreciate the size options (30ml or 50ml), so you can start small, then upgrade when it becomes a staple in your glow and tone-care routine.
