If the 30g convinced you — or you already know your skin gets along with glutathione and niacinamide — this is the size to run a proper twelve-week course on.\u003c\/p\u003e\u003ch2\u003e50,000ppm glutathione\u003c\/h2\u003e\u003cp\u003ePpm is parts per million, so this is 5% glutathione — a genuinely high concentration for an ingredient usually dosed in fractions of a percent. Glutathione is the antioxidant Korea has used for years for radiance, now defining the tone category in the US.\u003c\/p\u003e\u003ch2\u003eNiacinamide, adenosine, bifida ferment\u003c\/h2\u003e\u003cp\u003eNiacinamide is one of the best-studied ingredients for the look of uneven tone; adenosine is a long-established Korean fine-line ingredient; bifida ferment supports a resilient-feeling barrier while the actives work.\u003c\/p\u003e\u003ch2\u003eBooster-H technology\u003c\/h2\u003e\u003cp\u003emedicube’s patented delivery system, reported by the brand to enhance efficacy up to 3X. Designed to pair with the brand’s AGE-R devices as a conductive serum — and complete on its own without one.\u003c\/p\u003e\u003ch2\u003eRealistic timelines\u003c\/h2\u003e\u003cp\u003eBrightening is gradual even at 5%: expect eight to twelve weeks of daily use, with sunscreen every morning. Without SPF, new pigment forms as fast as old pigment fades.\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.\u003c\/p\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003ch3\u003eIs this the same formula as the 30g?\u003c\/h3\u003e\u003cp\u003eYes — identical formula, larger bottle, better value per ml.\u003c\/p\u003e\u003ch3\u003eHow long does 50ml last?\u003c\/h3\u003e\u003cp\u003eAround three months of twice-daily use — conveniently, the length of a full brightening course.\u003c\/p\u003e\u003ch3\u003eCan I use it with vitamin C or retinol?\u003c\/h3\u003e\u003cp\u003eYes — niacinamide and glutathione layer well with both. Introduce one new active at a time.\u003c\/p\u003e\u003ch3\u003eIs 5% glutathione irritating?\u003c\/h3\u003e\u003cp\u003eIt’s an antioxidant rather than an exfoliating acid, so it’s well tolerated. Patch test if your skin reacts easily.\u003c\/p\u003e\u003ch3\u003eDo I need the medicube device?\u003c\/h3\u003e\u003cp\u003eNo — the device may aid absorption, but the serum works fully on its own.\u003c\/p\u003e\u003ch2\u003ePairs well with\u003c\/h2\u003e\u003cp\u003ePrep with the \u003ca href=\"https:\/\/k-touch.us\/products\/medicube-age-r-glutathione-glow-toner-140ml\"\u003eAGE-R Glutathione Glow Toner\u003c\/a\u003e.
