A Korean glutathione brightening serum that looks simple but delivers an extraordinary concentration of actives — 604,074ppm lingonberry extract, 50,000ppm niacinamide, 40,000ppm tranexamic acid, and a full glutathione antioxidant network that works together to fade dark spots, even skin tone and deliver a visible glow. Completed low-irritation testing with a 0.00 irritation index — suitable for sensitive skin.

• Vaccinium Vitis-Idaea (Lingonberry) Fruit Extract 604,074ppm — the base of this serum at over 60% concentration; lingonberry is rich in natural vitamin C, antioxidants and polyphenols that brighten dull skin and protect against oxidative damage that causes uneven tone
• Niacinamide 50,000ppm (5%) — one of the highest niacinamide concentrations available; inhibits the transfer of melanin to skin cells, visibly reducing dark spots, hyperpigmentation and uneven tone with consistent use
• Tranexamic Acid (TXA) 40,000ppm — targets stubborn hyperpigmentation and post-acne marks at the source; works synergistically with niacinamide and alpha-arbutin for a multi-pathway brightening effect
• Glutathione + Stable Vitamin C (3-O-Ethyl Ascorbic Acid) — glutathione acts as a master antioxidant that delivers vitamin C more efficiently through an oxidation-reduction network; together they neutralize free radicals and support a brighter, more even complexion
• Alpha-Arbutin + Bisabolol — alpha-arbutin inhibits melanin production while bisabolol calms and soothes skin, making this formula effective for both brightening and sensitive skin care
• Panthenol 5% + Ceramide NP + Beta-Glucan — barrier-support trio that keeps skin hydrated, comfortable and resilient throughout the brightening process — no dryness, no irritation

After cleansing and toning, apply 3–5 drops and gently spread over the face. Follow with moisturizer. Use SPF in the morning. Suitable for all skin types including sensitive.
