ZEROID Intensive Hydrating Ampoule

Ingredient analysis and how the ad lines read

Read on 2026-09-20

What is this product?

A very short, humectant-focused hydrating serum built around Saccharide Isomerate and Sodium Hyaluronate, suitable for sensitive or very dry skin that wants hydration without added fragrance. The 48-hour and percentage claims are not backed by disclosed test details.

What makes it different?

The formula lists only seven ingredients, which is unusually minimal for the category. Two humectants do the work: Saccharide Isomerate sits third and Sodium Hyaluronate fifth, with a butylene glycol base and citric acid plus sodium citrate buffering the pH. No added fragrance or essential oil ingredients appear in the list. Concentrations and test support for the brand's numbers are not disclosed on the page checked.

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.
