What is this product?

Centellian24's 우유피부 글루타치온 토닝 부스팅 앰플 is a 30ml dropper-dispensed Korean ampoule with a 42-item label and a pigment stack deeper than most: niacinamide at 4, tranexamic acid at 11, bisabolol at 12, glutathione at 16 and ascorbic acid at 30, alongside a milk exosome preparation at 13, melatonin at 14 and a run of 14 free amino acids at 15 through 29. The headline ingredient sits lowest of the group. Glutathione is printed in its reduced, oxidation-labile form at position 16, below four solvents and two emollient esters, with no disclosed amount and no stabilised derivative named, while the ingredients with the strongest published pigment work sit far higher and are not in the product name. Coco-caprylate/caprate at 2 and isostearyl isostearate at 5 make this a light emulsion rather than the thin concentrate ampoule implies. The Olive Young record confirms a completed functional-cosmetic filing without naming which function it covers. Fragrance-free, alcohol-free, no acid exfoliant.

What makes it different?

A pigment stack running five ingredients deep across four separate mechanisms, set against zero disclosed concentrations and zero cited tests. Two unusual entries the category rarely carries: a milk exosome preparation at 13, whose particle characterisation and cargo are nowhere disclosed, and melatonin at 14, a hormone used here as an antioxidant with a thin topical literature. Fourteen free amino acids run consecutively from 15 to 29 and include glycine and cysteine, two of the three residues glutathione itself is built from, which reads as a precursor-supply strategy the label never explains. Tyrosine also sits in that run, at 22, which is the substrate tyrosinase converts toward melanin, an internal tension worth naming on a product sold on a toning axis even though the amount at that position is trivial.

What is in it?

The full ingredient list as the brand publishes it, in the printed order. Each name links to what we know about that ingredient.

This brand publishes its ingredient list in Korean only. Names below are the matching INCI names from the Korean Cosmetic Association ingredient dictionary, except 2 with no dictionary entry, left in Korean.

Key ingredient

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: Coco-Caprylate/Caprate, Isostearyl Isostearate, Sodium Stearoyl Glutamate, Tocopheryl Acetate

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.
