Illiyoon Ceramide Ato Gentle Skin Toner

Ingredient analysis and how the ad lines read

Read on 2026-09-24

What is this product?

A 250ml hydrating skin from a Korean sensitive skin line, sold on the brand's own store, with a ceramide printed at 45 ppm and a humectant base. The brand page carries two ingredient lists that disagree: the text notice names lavender, tea tree and chrysanthemum oils, the detail image does not. Neither lists added fragrance.

What makes it different?

Two things stand out. The ceramide level is printed, 45 ppm, on both lists the brand shows. And the brand's own page shows two different full ingredient lists for this bottle, one with three essential oils and one without, so readers who avoid essential oils should check the pack in hand.

Did the ad claims hold up?

We checked 32 lines this product advertises against the ingredient list and public documents. 16 of them look likely, though none are proven outright.
