Ingredient analysis and how the ad lines read

Read on 2026-09-06

What is this product?

A water-based toner pad whose 44-item list opens with niacinamide in second position, followed by multiple humectants, with tranexamic acid, ascorbic acid, ascorbyl glucoside and glutathione placed from item 25 onward. Concentrations are not given in the ingredient list.

What makes it different?

Niacinamide is the second of 44 ingredients, the highest placement of any named active. Tranexamic acid, ascorbic acid, ascorbyl glucoside and glutathione all appear from item 25 to item 37, so their weights are likely small. Gluconolactone at item 15 adds a polyhydroxy acid, and alcohol at item 36 is a drying alcohol to note for sensitive skin.

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