medicube Collagen Glow Booster Serum 15ml

A serum with a milky, translucent texture that sits somewhere between a gel and a light cream. Medicube designed it in a 15 ml size — easy to take on the go or to try out before committing, with enough product to genuinely see what the formula does to your skin over two to three weeks.

Texture and key ingredients — The base is a water-in-oil emulsion stabilised with Polyglyceryl-4 Oleate and Peg-30 Dipolyhydroxystearate, which gives it that soft, pearlescent finish — neither too runny nor sticky. Niacinamide and Hydroxypropyltrimonium Hyaluronate keep the surface of the skin hydrated, while Ceramide NP supports the skin barrier. Going deeper, Hydrolyzed Collagen and Hydrolyzed Elastin deliver small protein fragments, and Hexapeptide-2 and Adenosine round things out by targeting skin texture and fine surface lines. Milk Protein Extract, Beta-Glucan and Chlorella Vulgaris Extract nourish and soothe, while Fructooligosaccharides, Glucose and Fructose help maintain hydration levels. The airless twist-and-click bottle keeps the formula sealed off from air between uses.

How to use it — Morning and evening, on clean, dry skin. Twist the button anticlockwise to unlock, press to dispense two to four pumps depending on what your skin needs that day, then pat the serum gently onto your face, neck and décolletage — no rubbing. Twist the button back to lock, preventing any accidental dispensing. The brand also suggests mixing one pump directly into your usual moisturiser or serum to adjust the level of actives depending on the season.

• 15 ml size — ideal for travel or for trying the formula before moving up to a larger size.
• Airless twist-and-click bottle: the serum stays protected from oxidation between uses and each press delivers a consistent dose.
• Ceramide NP (exact INCI name): a phospholipid naturally found in the skin barrier that helps limit transepidermal water loss.
• Hexapeptide-2 and Adenosine: two distinct actives targeting skin texture and fine surface lines respectively — both listed in the INCI.
• Contains fragrance components (Benzyl Salicylate, Limonene, Linalool, Geraniol, among others): worth bearing in mind for very sensitive skin.
