What is this product?

MEDICUBE Zero Pore One-Day Peptide Serum is a 30ml pore serum that earns its pore claims through ingredients rather than through its own name: it carries Korean functional-cosmetic certification, with niacinamide notified for whitening and adenosine for wrinkle and elasticity care, plus a glycolic, salicylic and capryloyl salicylic acid trio that decongests pores. Buy it for that, not for the peptides on the front, because MEDICUBE publishes no concentration for any of those five actives and no pH, while the ten peptides it is named after are the only things it does put a figure on, all in parts per billion.

What makes it different?

Two of its three marketing claims have a named ingredient behind them, which is rarer than it sounds: niacinamide and adenosine are both Korea-notified functional actives, and the third rests on a real exfoliating acid trio. The gap is between the product's name and its label. Ten peptides are listed separately and every one is dosed in parts per billion, on a serum sold as a peptide serum.

What is in it?

The full ingredient list as the brand publishes it, in the printed order. Each name links to what we know about that ingredient.

This brand publishes its ingredient list in Korean only. Names below are the matching INCI names from the Korean Cosmetic Association ingredient dictionary.

Key ingredient

Ingredients with no mark are ones we found nothing notable about, and when marks overlap on one ingredient we show the caution first.

We could not place these in the list above: Polysorbate 80, Sorbitan Laurate, Sorbitan Stearate, Cetyl Palmitate, Salicylic Acid

Did the ad claims hold up?

We checked 2 lines this product advertises against the ingredient list and public documents. None of them hold up on their own. They are partly right at best.

Claims translated from Korean, originals preserved.

Each line is quoted as the brand published it, and each one was read on its own against the ingredient list and the documents the brand publishes.
