Medicube’s Glutathione Glow Serum is a radiance-boosting “skin booster” serum designed to brighten dull skin, improve elasticity, and support a stronger skin barrier for a smoother, more luminous complexion. Formulated with an impressive 50,000ppm glutathione, it helps enhance clarity and glow while targeting the look of uneven tone, blemishes, and pigmentation. The lightweight texture layers easily into your routine, leaving skin looking fresher and more radiant without feeling heavy.

The formula combines brightening and firming actives in Medicube’s Active Glow-zom Technology, featuring glutathione, niacinamide, and adenosine to boost radiance, smooth the look of fine lines, and improve overall skin vitality. Patented skin-like collagen helps support elasticity for a plumper, lifted look, while bifida ferment lysate helps strengthen the skin barrier and improve skin resilience, especially helpful for skin that feels stressed or sensitized.

With consistent use, the serum helps fade the appearance of spots and discoloration, while visibly improving the look of common expression lines such as crow’s feet, smile lines, and forehead lines for a brighter, more youthful-looking glow. For optimal results, Medicube recommends pairing it with the AGE-R Booster-H device, which is designed to enhance absorption of active ingredients, Medicube notes the routine can feel up to 3x more effective when used together. The serum is hypoallergenic tested and also tested for wrinkle and brightening (“whitening”) improvements.
