innisfree green tea seed hyaluronic serum

Ingredient analysis and how the ad lines read

Read on 2026-09-23

What is this product?

An 80 mL lightweight hydrating serum from a Korean brand's green tea line, now sold on the brand's own store under a newer display name while its English name field keeps green tea seed hyaluronic serum. The statutory list has 54 entries and discloses levels for seven: green tea seed oil at 2,609 ppm, green tea extract at 366 ppm, and five hyaluronic acid forms from 103 ppm down to 0.01 ppm. It is humectant led with niacinamide high on the list, a light oil phase of the seed oil and squalane, no silicone, no ethanol, no paraben and no phenoxyethanol. It has no fragrance entry but carries five essential oils with declared limonene and citral, and lactic acid appears near the end of the list. The page cites a 2022 heat redness test on 30 women and perception questionnaires from 2023 and 2024; its capsule hyaluronic acid and penetration figures have no published method.

What makes it different?

Three things set it apart. First, disclosure: the statutory list prints levels for seven entries, so the hyaluronic acid story can be checked, and it shows five forms at small levels rather than one headline ingredient. Second, the redness claim rests on a named 2022 test with dates and panel, which is more than a percentage alone, while the satisfaction figures are openly questionnaires. Third, against the cream from the same line, the landed records share 36 of 54 entries and this serum alone adds niacinamide, a vitamin C derivative and alkyl glucoside emulsifiers. Against that: the capsule and double green tea water are trade names not visible on the list, and five essential oils sit on a list with no fragrance entry.

What is in it?
