Ingredient analysis and how the ad lines read

Read on 2026-09-19

What is this product?

A thin, leave on first step serum from a Korean dermatological skincare brand, sold in a 150ml bottle and positioned around cooling facial heat and firming enlarged pores. Its 33 item Korean ingredient list opens with water and three humectants, puts niacinamide fifth and adenosine fifteenth to back a dual brightening and wrinkle functional filing, and carries a cold receptor agonist at nineteenth, glacial water at twenty first, caffeine and a coffee seed extract. There is no fragrance entry, no essential oil, no drying alcohol and no oil, butter or silicone. The brand attaches a minus 5.4 degree cooling figure to its headline with no method disclosed, and its launch copy credits a coffee collagen that no printed entry is named after.

What makes it different?

It pairs both notified actives for a dual brightening and wrinkle filing with a cold receptor agonist in a 33 entry water base that carries no oil, silicone or fragrance. Against the four same line sibling formulas it was compared with, it is the only one carrying tannic acid, a coffee seed extract, erythritol, xylitol, a liquorice salt and hydrolyzed extensin.

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.
