Ingredient analysis and how the ad lines read

Read on 2026-09-21

What is this product?

A hydration-focused ampoule with hyaluronate and ceramides, suited to dry or sensitive skin, and free of added fragrance and drying alcohol.

What makes it different?

The formula leads with water, butylene glycol, glycerin and niacinamide at the top of the list, then adds sodium hyaluronate at a printed 1001 ppm. Barrier lipids (ceramide NP, cholesterol, fatty acids, sphingolipids) sit in the later half at very small printed levels, down to 0.75 ppm for ceramide NP. The list has no fragrance, essential oils, ferments or drying alcohols, which supports the sensitive-skin positioning.

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.

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