• 5% Glutathione (50,000ppm) — Master Antioxidant Brightener — Glutathione is the body's most powerful natural antioxidant. At 5% concentration (fourth ingredient), this is one of the most potent Glutathione serums in K-beauty. Brightens dull skin, fades dark spots, and provides deep antioxidant protection against environmental stress.
• 88 Billion Flexible Liposomes/mL — Deep Delivery — the Glutathione is encapsulated in flexible liposomes made from Hydrogenated Lecithin and Cholesterol. Unlike rigid liposomes, these deform to squeeze through skin layers and deliver actives deeper. The technology that makes 5% Glutathione actually reach where it needs to go.
• Niacinamide + TXA — Triple Brightening Pathways — Niacinamide fades dark spots, evens tone, and minimizes pores. Tranexamic Acid (TXA) targets stubborn pigmentation from yet another angle. Combined with Glutathione, three of the most effective brightening actives working simultaneously from three different mechanisms.
• Cysteine + Glycine + Carnitine — Glutathione Support Amino Acids — Cysteine and Glycine are the two amino acids your body uses to make Glutathione naturally — including them supports the formula's brightening pathway. Carnitine adds additional antioxidant support. Three amino acid derivatives that deepen the Glutathione effect.
