The 50 ml dropper bottle of medicube's glutathione serum, dosed at 50,000 ppm glutathione refined to 99.4 % purity, with niacinamide, adenosine and collagen. This is the large format of the 30 g version — in the AGE-R line the small bottle is the one that sells you the big one, once you are using it with the Booster Pro device daily.
Who it's for. Dull skin and the appearance of uneven tone, on people already through a smaller bottle and using it every day.
How to use. After toner, dispense 2-3 drops with the dropper and press over face and neck, morning and night, then moisturizer. It doubles as the glide layer for a Booster Pro session. Sunscreen every morning.
Key active. Glutathione at 50,000 ppm and 99.4 % purity, with niacinamide, adenosine and collagen; glutathione is used in Korean formulation as a skin-conditioning agent, and the topical form is a cosmetic and is not the clinic procedure that made the ingredient known. In Korean labelling “whitening” describes evenness of tone, not lightening the skin. Topical collagen does not replace the collagen in your skin.
Sourced in Seoul. This is the Korean domestic SKU, not a reformulated export version.
