ONE THING

ONE THING 병풀 추출물 토너

Ingredient analysis and how the ad lines read

Read on 2026-09-20

What is this product?

A minimal four-ingredient centella toner built on 94% centella leaf water with 1% centella extract, suited to sensitive skin looking for simple soothing and hydration. If you prefer formulas with niacinamide, exfoliants or added actives, this one-ingredient-focus toner will feel too basic.

What makes it different?

The formula is unusually short, four items total, with centella leaf water at 94% first and centella extract at 1% fourth with a printed concentration. There is no fragrance, no essential oils and no drying alcohol in the list, which keeps it friendly to reactive skin. Both size options, 150ml and 300ml, are noted on the page. Concentrations for the two centella components are stated, which is not always the case for single-ingredient toners.

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.

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: Butylene Glycol
