ShionLe LAMINARIA COLLAGEN FIRMING MASK

What is this product?

A thick, slippery 10-sheet mask that is worth buying for how it feels and not for what it is named after. Worth reaching for as a genuinely viscous essence and a rich 15 to 20 minute treatment on skin that tolerates fragrance and alcohol: carbomer, xanthan gum and dextrin build real body, and 17 free amino acids plus five peptides fill out the tail. Skip it on reactive or barrier-compromised skin, because 변성알코올 sits fifth of 57 and 향료 fourteenth, with no allergen breakdown. The firming story is the weak part. Soluble collagen is printed at 50 ppm in nineteenth place, laminaria extract at 10 ppm in twenty-second, the five peptides occupy the last five slots, and the product's own disclosure row reads 심사 필 유무 : 해당없음. Follow with a cream.

What makes it different?

The label prints concentrations for both ingredients in the product name, which lets a reader see that 변성알코올 and 향료 are placed well ahead of the collagen and the laminaria the mask is sold on.

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: 폴리솔베이트80, 수크로오스팔미테이트, 카프릴릭/카프릭트라이글리세라이드, 하이드로제네이티드레시틴

Did the ad claims hold up?

We checked 5 lines this product advertises against the ingredient list and public documents. One of them holds up. The rest are only partly right or have nothing behind them.

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.
