COSRX The Alpha-Arbutin 2 Discoloration Care Serum is a highly concentrated brightening serum that specifically targets skin discoloration, pigmentation spots, and uneven skin tone. With its powerful combination of active ingredients, it delivers a visibly more even, clearer, and more radiant complexion—ideal for minimizing the appearance of past blemishes or sun damage.

The serum features alpha-arbutin as its main active ingredient, known for its ability to regulate melanin production and thus visibly reduce pigment spots. Tranexamic acid supports this effect by evening out skin tone and making the skin appear fresher. The formula is complemented by niacinamide, which refines the skin’s texture, regulates sebum production, and enhances the skin’s radiance. N-acetylglucosamine (NAG) supports these effects by stimulating cell renewal and facilitating the penetration of the brightening active ingredients—for a more even complexion with a natural glow.

Ferulic acid and glutathione, two powerful antioxidants that protect the skin from external influences and visibly brighten the complexion, provide an additional synergistic effect. Ferulic acid enhances the effect of other active ingredients, while glutathione makes the skin appear fresher and more vibrant. The lightweight, fast-absorbing texture makes the serum an ideal step in any skincare routine—it can be used morning and night without feeling heavy.

The COSRX The Alpha-Arbutin 2 Discoloration Care Serum is suitable for all skin types, but especially for skin with pigmentation irregularities, a dull complexion, or visible spots caused by sun exposure or hormonal changes. It promotes a balanced complexion, increased radiance, and a more even skin tone.
