ShionLe Laminaria Greenery Serum

What is this product?

ShionLe's Laminaria Greenery Serum rests its case on the kelp, and that part is the best evidenced thing in the document: the kelp juice is printed second of 46 ingredients at a declared 20 percent, ahead of glycerin, in both of the printed versions of the list this document found. Two things sit against it. A second kelp entry appears near the end at 0.0002 percent, and ShionLe publishes no test behind the line claiming that kelp alginate adsorbs sebum on skin the copy calls sensitive, a formula that prints 향료 in both versions. The brand's own product information block records the serum as filed for 주름개선 기능성, which is the axis 아데노신 serves.

What makes it different?

The distinguishing fact is a disclosed number where brands usually print only a name: the kelp juice carries 20 percent on the label itself, second of 46. It is built as a thin syrup rather than an oil serum, thickened with gums and carrying 나이아신아마이드 and 아데노신. The brand's own product information block on m.shionle.com prints the filing line 기능성 화장품의 경우 화장품법에 따른 식품의약품안전처 심사 필 유무 : 주름개선 기능성, so the registered axis is wrinkle care, which is the axis 아데노신 serves; the same block prints no 미백 filing, so 나이아신아마이드 sits in the formula without a registration behind it. No compliant level is published on either surface. A marine and collagen group of algae, hijiki, Gelidium cartilagineum and three collagen forms travels together in both printed versions of the list, at the tail in the anchor version and just past the humectants in the brand version. Eight exfoliating acid tokens return zero hits against either version, so it layers under actives instead of competing with them, but it is fragranced.

Did the ad claims hold up?

We checked 3 lines this product advertises against the ingredient list and public documents. None of them hold up on their own. They are partly right at best.

Claims translated from Korean, originals preserved.

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.
