medicube Glutathione Glow Serum 30g

A serum made for skin that wants to glow — without looking flat or overdone. medicube's Glutathione Glow Serum packs its active ingredients into a carefully balanced formula — not too runny, not too thick — designed to work seamlessly with the Booster-H device. Use it on its own or paired with the device; either way, it quietly becomes part of your routine and delivers results you'll notice over time.

Texture and key ingredients — The serum is built around Glutathione at 500 ppm, an antioxidant that helps even out skin tone and fade dullness. Niacinamide works alongside it to smooth out uneven patches, while Adenosine helps keep skin feeling firm. For hydration, the formula brings together five forms of hyaluronic acid — Sodium Hyaluronate, Sodium Hyaluronate Crosspolymer, Hydrolyzed Hyaluronic Acid, Hydroxypropyltrimonium Hyaluronate and Hyaluronic Acid — reaching different depths of the skin. Squalane and Ceramide NP reinforce the skin barrier, while Bifida Ferment Lysate, a fermented ingredient, helps build skin's resilience. The texture is stabilized with Xanthan Gum and Carbomer for a smooth, non-sticky finish. Patch-tested for daily use.

How to use — Apply a generous layer over the area you want to treat — face, eye contour, forehead. If you're using the Booster-H device, add a small extra amount directly onto the roller heads before each pass. The formula is designed for daily use: it won't dry out your skin, leaving it ready to absorb whatever you apply next.
