What is this product?

A 30ml brightening serum whose name states two concentrations, niacinamide 10 and TXA 4, that its statutory ingredient statement does not. The 51 entry statement carries no percentage and no ppm anywhere, while the brand's own sibling sheet mask prints 5% and 1,000ppm inside its equivalent statement. The product does carry a real single function whitening notice with no filing number, niacinamide third and tranexamic acid fourth in the list, and, unadvertised by the name, five fixed plant oils in the middle of it.

What makes it different?

This record exists to separate a name from a label. The two numerals in 나이아신아마이드 10 TXA 4 recur in the statutory 제품명 및 모델명 row, which makes them a registered name rather than a disclosure, and the statutory ingredient statement beside that row prints no concentration for any of its 51 entries; the brand's page contains no occurrence of 10% at all. The control that makes this readable rather than speculative was archived in the same run: the brand's own dark spot sheet mask, a different product number under a closely related name, prints 나이아신아마이드(5%) and 트라넥사믹애씨드(1,000ppm) directly inside its statutory statement, and its notice row reads 미백 주름개선 2중 기능성 화장품 against this product's single function 미백 기능성 화장품. The second thing this record surfaces is not in the name at all: five fixed plant oils run through the middle of the list alongside a medium chain triglyceride, a sucrose ester and a hydrogenated lecithin, which is what puts ten of this statement's entries on those lists. The brand's own markup also holds a stray line about keeping pads from drying out, template residue from a different format, but it is commented out in both archived files and does not render, so the directions a reader sees are one line long.

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, except 10 with no dictionary entry, left in Korean.

Each line is quoted as the brand published it, and each one was read on its own against the ingredient list and the documents the brand publishes.
