✨ Glutathione Glow Serum – a hydrating serum for brighter, more even and plumper skin
The medicube Glutathione Glow Serum – currently officially named AGE-R Glutathione Glow Serum – is a radiance-boosting, hydrating serum for dull, uneven-toned and loss of elasticity skin.
The formula combines 500 ppm glutathione with niacinamide, Bifida Ferment Lysate, adenosine, soluble collagen, Ceramide NP and various hydrating ingredients. The aim is not just a shiny finish: the serum supports a more hydrated, smoother, plumper and naturally radiant complexion.
Its easily layerable texture makes it suitable for both morning and evening routines and it can be used alone – no AGE-R device is required.
✨ What does it do?
- Supports a brighter, fresher complexion: glutathione and niacinamide together focus on caring for dull, uneven tone.
- Helps create a more even appearance: with regular use, skin tone may appear clearer and more balanced.
- Hydrates and replenishes: glycerin, betaine, panthenol, beta-glucan and various hyaluronic acids help maintain skin moisture.
- Supports the skin barrier: Ceramide NP, squalane and hydrogenated lecithin complement the hydrating system.
- Supports plumper, more elastic skin: adenosine and soluble collagen help a smoother, more elastic appearance with their skin-conditioning effects.
- Contains fermented ingredient: Bifida Ferment Lysate enhances the formula’s skin-conditioning and hydrating side.
- Gives a dewy, hydrated glow finish: it aims for a softer, smoother and well-hydrated skin surface rather than a glittery shine.
🧬 Key active ingredients
500 ppm glutathione
Glutathione is an antioxidant ingredient that is central to the medicube Glow Serum’s radiance-boosting concept.
In the formula, together with niacinamide and other antioxidant and skin-conditioning ingredients, it supports a fresher, more even and naturally radiant complexion.
Niacinamide
A versatile form of vitamin B3 for skincare. It supports the skin barrier and hydration while contributing to a more even, fresher appearance.
Its high position in the ingredient list indicates it is one of the formula’s key active components.
Bifida Ferment Lysate
A fermented skin-conditioning ingredient that fits well into formulas supporting hydration and skin comfort.
In this serum, alongside the glutathione–niacinamide system, it complements the creation of a more hydrated, smoother skin feel.
Ceramide NP + squalane
Ceramide NP is an ingredient similar to the skin’s natural lipid barrier, while squalane is a lightweight skin-softening lipid.
Together they help reduce moisture loss and support a softer, more comfortable skin surface.
Hyaluronic acid complex
The formula contains several types of hyaluronic acid, including sodium hyaluronate, hydrolyzed hyaluronic acid, hyaluronic acid, sodium hyaluronate crosspolymer and sodium acetylated hyaluronate.
These help bind water on the skin surface, providing a plumper, smoother and more hydrated skin feel.
Panthenol + beta-glucan
Two hydrating and skin-conditioning ingredients that support skin comfort and complement the formula’s barrier care.
Soluble collagen + adenosine
Skin-conditioning ingredients that complement the serum’s radiance-boosting concept by supporting a softer, smoother and more elastic appearance.
📊 What did medicube’s tests show?
In a four-week study published by medicube, with the Glutathione Glow Serum used alone:
- visible spots decreased by 4.8%,
- skin radiance increased by 3.5%,
- measured melanin level decreased by 3.4%.
Data are from the medicube published AGE-R Glutathione Glow Serum test report. Individual results may vary.
🎯 Who is it recommended for?
Glutathione Glow Serum may be a particularly good choice if:
- your skin looks dull or tired,
- your skin tone is uneven,
- visible spots bother you,
- you want to restore your skin’s natural radiance,
- your skin feels dehydrated or tight,
- you want a plumper, smoother and more elastic complexion,
- you are looking for an easily layerable glow serum.
🧴 Texture and place in the routine
A light, hydrating serum that leaves a soft, dewy finish on the skin without a classic heavy cream feel.
After cleansing and toner, apply an appropriate amount to the face and neck, then gently pat in.
Follow with a moisturiser.
Suitable for use morning and evening. During the day, finish your routine with sunscreen.
💗 Why do we love it?
Because it is not just a glutathione-based “glow serum”.
Alongside niacinamide and glutathione, it also contains bifida ferment, ceramide, squalane, panthenol, beta-glucan, various hyaluronic acids, collagen and adenosine, so the radiance boost is complemented by a serious hydrating and barrier-supporting system.
Thanks to this, it may also be interesting if your skin feels dehydrated, less plump or less comfortable alongside dullness.
Its light texture makes it easy to incorporate into your routine without needing to build a completely new active treatment system around it.
❓ Q&A
Is the AGE-R device needed?
No. The Glutathione Glow Serum can be used as a standalone skincare serum.
Medicube also demonstrates combined use with the AGE-R device, but the device is not necessary to include the product in your daily routine.
What is the difference between Glutathione Glow Serum and Glutathione Glow Capsule Cream?
The Glutathione Glow Serum is a lighter, concentrated serum step combining glutathione, niacinamide, bifida ferment, ceramide and various hydrating ingredients.
The Glutathione Glow Capsule Cream is a hydrating cream containing glutathione capsules, peptides, ceramide and collagen, used as the final step in the routine.
The two products can be used together: serum first, then cream.
Can it be used morning and evening?
Yes. It can be incorporated into both routines. In the morning, use sunscreen after serum and moisturiser.
Is it more of a radiance-boosting or hydrating serum?
Both. Glutathione and niacinamide primarily support a brighter, more even complexion, while bifida, panthenol, squalane, ceramide, beta-glucan and various hyaluronic acids provide a strong hydrating and barrier care background to the formula.

Több éve hogy áttértem koreai kozmetikumokra,beleértve a hajápolást és sminket is,tehát sok márkát/terméket teszteltem mire az állandó készletem kialakult.Közben az idő is telt,a bőröm is változott ezért kerestem olyan márkát ami a bőröregedésre kínál csúcstermékeket.Ez a szérum..jó ég,hogy utálom az illatosított arcápolókat,de ez!Most először képes lennék csak az illata miatt is megvenni egy szérumot😯annyira jó hatással van még a lelkemre is:)Persze félretéve a frézia illatot (én annak érzem) ez a szérum csodálatos fényt biztosít tápláltan hagyva a bőrt.Hosszútávon is bízom benne ezért megrendeltem hozzá a krémet is.Részemről nagy dolog ilyen esélyt adni egy új terméknek,szóval bőven látok benne hatékonyságot.
