Ingredient analysis and how the ad lines read

What is this product?
W.Skin Laboratory (W.피부연구소) AC+ Trouble Patch is a thin, clear blemish patch sold on the brand's own Korean store as a two-pouch unit of 56 patches, each 28-patch pouch closing with a zip seal. Its statutory ingredient table prints eight entries: an acrylates copolymer, salicylic acid, tea tree leaf oil, purslane, centella and green tea extracts, butylene glycol and 1,2-hexanediol. There is no fragrance entry and no alcohol entry, but salicylic acid is an exfoliating BHA and the tea tree entry is an essential oil. The brand cites a 2021 human-use test and assigns pigmentation and whitening roles to plant extracts, while its notice states no functional-cosmetic filing.
What makes it different?
A thin clear spot patch sold as two zip pouches, whose eight-entry list pairs a salicylic acid entry with three plant extracts and an essential oil; the brand supports it with a 2021 tolerance and soothing test cover page and ingredient callouts that outrun the statutory filing.
