suolim Tannin Brightening Mask

What is this product?

A 25 ml brightening sheet mask sold direct by its Korean brand, declared on the brand's own image as a two-type functional cosmetic for brightening and wrinkle improvement. The ingredient list was read from the brand's detail image, forty four entries with zero unreadable characters. Water, glycerin, methylpropanediol and hexanediol open it, followed by niacinamide printed at 20,037.5ppm, panthenol printed at 1,000ppm, pyridoxine, sodium ascorbyl phosphate, calcium pantothenate and tocopheryl acetate. Eight starred plant extracts form the brand's tannin complex: Diospyros kaki leaf, grape fruit, safflower flower, coffee seed, Polygonum cuspidatum root, chestnut shell, Camellia sinensis leaf and Zanthoxylum piperitum fruit. Matricaria flower extract, madecassoside, four plant oils, adenosine and sodium hyaluronate follow, and fragrance is the last entry. No acid-suffixed entry, no exfoliating acid and no ethanol. The brand shows a 24 hour patch test summary for this mask. No pH figure and no English ingredient list appear on any surface collected.

What makes it different?

What sets this sheet apart on its own label is the pairing of a printed niacinamide amount, 20,037.5ppm at position 5, with adenosine and a four-vitamin set, alongside eight plant extracts the brand brands as a tannin complex, all declared under a brightening and wrinkle-improvement functional status. It is fragranced, with fragrance as the last entry and no allergen names printed. The brand's safety evidence is a patch test summary naming this mask; its effect claims are unmeasured in the collected material. No comparison record was used.
