{"product_id":"medicube-age-r-glutathione-glow-serum-30g","title":"medicube - AGE-R Glutathione Glow Serum 30g","description":"\u003cp\u003emedicube AGE-R Glutathione Glow Serum carries 50,000ppm glutathione — one of the highest concentrations in K-beauty — alongside niacinamide, adenosine and bifida ferment.\u003c\/p\u003e\u003ch2\u003e50,000ppm — what that means\u003c\/h2\u003e\u003cp\u003ePpm is parts per million, so 50,000ppm works out to 5% glutathione. For an ingredient usually dosed in fractions of a percent, that’s a genuinely high concentration, and the headline reason this serum anchors the AGE-R line.\u003c\/p\u003e\u003ch2\u003eGlutathione and niacinamide together\u003c\/h2\u003e\u003cp\u003eThe defining brightening pair of the moment: glutathione for radiance and antioxidant protection, niacinamide as one of the best-studied ingredients for the look of uneven tone. Together they target dullness and dark spots from two directions.\u003c\/p\u003e\u003ch2\u003eBifida ferment for the barrier\u003c\/h2\u003e\u003cp\u003eA fermented ingredient long used in Korean and Japanese formulas to support a resilient-feeling skin barrier — useful in a serum built around actives.\u003c\/p\u003e\u003ch2\u003eAdenosine and collagen\u003c\/h2\u003e\u003cp\u003eAdenosine is among the most established Korean ingredients for the look of fine lines. On collagen, an honest note: topically it works as a surface humectant — the molecule is too large to rebuild anything deeper.\u003c\/p\u003e\u003ch2\u003eBooster-H technology\u003c\/h2\u003e\u003cp\u003emedicube’s patented delivery system, which the brand reports enhances serum efficacy up to 3X. medicube built its name on at-home devices, and this serum is designed to pair with their AGE-R tools — though it works fine without one.\u003c\/p\u003e\u003ch2\u003eRealistic timelines\u003c\/h2\u003e\u003cp\u003eEven at 5%, brightening is gradual work: expect eight to twelve weeks of daily use, with sunscreen every morning. New pigment forms as fast as old pigment fades without SPF.\u003c\/p\u003e\u003ch2\u003eHow to use\u003c\/h2\u003e\u003cp\u003eAfter toner, apply an appropriate amount and pat gently into skin until absorbed. Follow with moisturizer, and sunscreen in the morning. Use morning and evening. If using an AGE-R device, apply the serum first as a conductive layer.\u003c\/p\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003ch3\u003eIs 5% glutathione too strong?\u003c\/h3\u003e\u003cp\u003eGlutathione is well tolerated even at high concentrations — it’s an antioxidant, not an exfoliating acid. Patch test if your skin reacts easily.\u003c\/p\u003e\u003ch3\u003eCan I use it with vitamin C?\u003c\/h3\u003e\u003cp\u003eYes — antioxidants layer well together. Introduce one new active at a time.\u003c\/p\u003e\u003ch3\u003eDo I need a medicube device for it to work?\u003c\/h3\u003e\u003cp\u003eNo. The device may aid absorption, but the serum is a complete product on its own.\u003c\/p\u003e\u003ch3\u003eWill it fade dark spots?\u003c\/h3\u003e\u003cp\u003eIt works on how they look, gradually, and sunscreen determines whether the progress holds.\u003c\/p\u003e\u003ch3\u003e30g or 50ml — which size?\u003c\/h3\u003e\u003cp\u003eSame formula.
