Benefits

Firmness Skin looks firmer where it goes soft first — the jaw, the neck, the sides of your mouth.

Fine lines Fine lines on your forehead and around your eyes look softer.

Tone Skin tone looks more even. Dark spots and red patches fade into the background.

Bounce Skin looks fuller and more bouncy instead of flat and tired.

Under makeup It is light enough to wear under makeup without rolling into little balls.

Skin type No perfume and no pore-blocking oils, so it is fine for skin that breaks out.

How we use

01 Serum goes on after your toner. Wash your face first. If you use a toner, that comes before this. Then the serum. Thick creams and oils go on after, never before.

02 Two or three drops. That covers your face and neck. The bottle holds 30 ml. Using more does not work faster, it just empties the bottle sooner.

03 Spread it, then tap it in. Smooth it on gently, following the shape of your face. Then tap lightly with your fingertips until it sinks in. Go upward on your neck.

04 Morning and night. Medicube says twice a day, and twice a day is what the two-week test measured. Finish with sunscreen in the morning. If you also use retinol or an acid, add them in slowly so your skin can keep up.

Ingredients

What does the work.

EGF 2.5 ppm. A tiny protein your own skin already makes. It tells skin cells to get busy. That is where the name EGF comes from.

NAD+ 1 ppm. A helper molecule that skin cells use for energy. You have less of it as you get older.

Niacinamide This one is fourth on the list, so there is a real amount in the bottle. It helps with uneven colour and keeps your skin barrier strong.

Adenosine Korea's health agency lists this as an official wrinkle-care ingredient. That is rare. Most skincare ingredients have no rules like that.

Ectoin Comes from tiny life forms that survive in salt lakes and hot springs. It helps skin hold water and handle wind, cold and pollution.

8 peptides Copper Tripeptide-1, Palmitoyl Tripeptide-5, Acetyl Hexapeptide-1, Acetyl Octapeptide-3, Oligopeptide-1, -2, -3 and Hexapeptide-11. Short chains of amino acids. They are the building blocks of proteins like collagen.

Also inside Collagen extract and sodium hyaluronate for a plumper look. Glutathione and a berry blend (cranberry, blueberry, raspberry, blackberry, lingonberry, bilberry, elderberry) for antioxidants. Rosehip oil and evening primrose to soften.

Not inside No alcohol. No added perfume. No essential oils.
