Description
MEDICUBE Glutathione Glow Serum is a concentrated “glow-boosting” treatment serum formulated to deliver brightening, radiance, and improved skin elasticity. Its standout feature is a high content of glutathione (claimed up to 50,000 ppm), paired with niacinamide, adenosine, collagen, bifida ferment lysate and multiple humectants/skin-identical ingredients.
The serum is designed to tackle dullness, uneven tone, pigmentation/spot concerns, as well as early signs of aging (loss of bounce, fine lines), while also supporting skin barrier, hydration, and overall skin health.
Size: 30G
Key Benefits
Brightening & even skin tone — Helps fade dark spots, post-inflammatory hyperpigmentation (PIH), and uneven tone thanks to glutathione + niacinamide.
Radiance & “glass-skin” glow — Leaves a luminous, dewy glow and reduces dullness; skin looks more awake and healthy.
Improved elasticity & firmness — With collagen + adenosine, it supports skin’s bounce and helps smooth early fine lines / skin texture for a plumper look.
Hydration & barrier support — Contains humectants (glycerin, betaine), skin-identical lipids (squalane, ceramide NP), various hyaluronic acid derivatives for deep hydration and to strengthen the skin barrier.
Antioxidant & anti-aging protection — Glutathione, tocopherol (vitamin E), glucosylrutin and other antioxidants help defend against free-radical damage and environmental stress, potentially reducing premature aging.
Gentle daily-use serum — Alcohol-free, formulation aims to be low-irritation and suitable even for sensitive skin.
Skin Type
Normal, dry, combination, and sensitive skin.
Skin that appears dull, tired, uneven tone or pigmented — good for those with dark spots, post-acne marks, or sun-induced pigmentation.
Skin that needs hydration + barrier support + antioxidant defence — as the serum combines humectants, antioxidants, and barrier-friendly ingredients.
Key Ingredients
Glutathione (claimed 50,000 ppm) — a powerful antioxidant; helps brighten skin by inhibiting tyrosinase (enzyme involved in pigmentation), supports detoxification of oxidative stress, helps even skin tone and reduce dark spots.
Niacinamide (Vitamin B3) — boosts barrier lipids, improves moisture retention, evens out skin tone, supports cell regeneration, helps with brightening and oil balance.
Adenosine — helps improve elasticity, smooth fine lines, supports skin renewal and firmness.
Collagen (skin-like / hydrolyzed / soluble) — added to support skin’s structural proteins, hydration, elasticity and plumping effect.
Bifida Ferment Lysate — a probiotic-derived ingredient that can help strengthen skin barrier, soothe skin, and improve skin resilience.
Humectants & moisture support — Glycerin, Betaine, PEG-8, Butylene Glycol, Sodium Hyaluronate (and cross-polymers), Hydrolyzed Hyaluronic Acid, etc., to draw water into skin and maintain hydration.
Lipids & barrier-supporting ingredients — Squalane, Ceramide NP, Tocopherol, etc. to help lock in moisture and restore skin barrier function.

Pregnancy an Nursing Safe
Likely Safe
This product contains Glutathione, which is likely safe to use during pregnancy and breastfeeding when applied in small amounts and used as directed but every pregnancy is different — we recommend consulting your healthcare provider before introducing new skincare products.
How to use
After cleansing and toning (and any light essence) — make sure skin is clean and slightly damp.
Dispense 2–3 drops (or a pea-sized amount) of the Glutathione Glow Serum onto your fingertips.
Gently spread and pat the serum over your face (and neck if desired) until absorbed. Because the formula includes humectants and barrier-supportive lipids, it should feel light but hydrating — pat gently to avoid unnecessary friction especially if your skin barrier is compromised.
Follow immediately with your moisturiser / barrier-repair cream to lock in hydration and additional barrier lipids (this is particularly important if your skin tends to be flaky or dry).
Frequency: Use once daily (preferably at night). If your skin tolerates well and you need extra brightening, you may use morning + night — but always follow with sunscreen in the morning if used.
Additional tips:
On days when your skin is more sensitive or flaky: consider using the serum only once or reduce frequency.
Make sure to apply broad-spectrum SPF during the day if using brightening/antioxidant serums regularly.
Maintain your barrier repair routine (moisturiser / cream) alongside this serum — brightening + barrier care balance tends to yield best results
