How do I unlock and dispense the serum?

After taking off the cap, rotate the button counterclockwise until the dispenser is active. MEDICUBE directs two to four clicks, or pumps, for each use. Apply the milky serum to the face, neck and décolleté with gentle pressing motions. Close the pen and turn its button clockwise when finished so it is locked before storing or carrying.

Should I use this serum in the morning or at night?

MEDICUBE directs use both morning and night on clean, dry skin. Apply the serum before a face cream and after any lighter, water-like steps in your routine. The brand also suggests mixing one pump into a serum or cream as an optional pro tip, while direct pressing application remains the primary direction for the product.

What does the Collagen Glow Booster Serum feel like?

The brand describes a smooth, milky texture with a luminous finish. Exact-product reviewers commonly describe it as dewy and soft, while some find the emulsion richer or oilier than expected. Two to four pumps is the official amount, and the final feel can vary with skin type and the products layered around it.

Does the hydrolyzed collagen rebuild skin collagen?

Hydrolyzed Collagen is present in the verified formula, but topical collagen should not be read as a promise that the serum rebuilds structural collagen. The finished-product studies report a narrower set of measured changes in hydration, moisture glow, visible line areas and elasticity-related markers after use, which are listed separately in the Real Results section.

Does the formula contain fragrance?

Yes. Fragrance (Parfum) appears in the current 41-item formula, along with benzyl salicylate, limonene, linalool, hexyl cinnamal, hydroxycitronellal, alpha-isomethyl ionone and geraniol. These are listed directly in the complete ingredient panel, so the serum should not be described as fragrance-free. Shoppers avoiding scented formulas can review those specific names before choosing it.

Is MEDICUBE Collagen Glow Booster Serum vegan?

No. The verified panel contains a dairy protein plus collagen and elastin in hydrolyzed form, all of which are animal-derived. MEDICUBE separately states that the product is not tested on animals, but that does not make the formula vegan. Shoppers avoiding animal-derived ingredients should rely on the complete ingredient list rather than the collagen or milk marketing name alone.

Can sensitive skin use this serum?

MEDICUBE includes sensitive skin in its all-skin-types positioning and describes the finished product as low-irritating. The current formula nevertheless contains Fragrance (Parfum) and several listed fragrance components. Those facts can coexist: brand positioning describes the tested product, while individual fragrance preferences and comfort can still differ from one routine to another.

PRODUCT DETAILS

MEDICUBE Collagen Glow Booster Serum is a 15ml pen-style milky serum for skin that looks dull, dry or less springy. The twist-and-click package is designed for portable use, while the lightweight emulsion leaves a soft, luminous finish rather than functioning as a heavy face cream.

The formula pairs glycerin with niacinamide, Milk Protein Extract, hydrolyzed collagen and elastin, Ceramide NP, adenosine and Sodium DNA, the ingredient behind the product's PDRN story. This blend supports hydration, surface conditioning and a smoother-looking finish; topical collagen is not presented as a replacement for structural collagen.

Use it on clean, dry skin in both morning and evening routines. Turn the button to unlock, click two to four times and pat the dispensed milk across facial skin, the neck and upper chest. Its targeted applicator and locking base make the 15ml format easy to keep in a routine or carry away from home.

Fragrance (Parfum), benzyl salicylate, limonene, linalool and other fragrance components appear in the verified formula. Milk Protein Extract, hydrolyzed collagen and hydrolyzed elastin are animal-derived ingredients, so this serum does not fit a vegan preference.
