Product Info

A multi-target brightening serum with 2% alpha-arbutin, tranexamic acid and niacinamide for visibly fading dark spots and post-blemish marks

COSRX's Alpha-Arbutin 2% Discoloration Care Serum takes a multi-target approach to uneven tone. Alongside 2% alpha-arbutin it combines tranexamic acid, niacinamide and N-acetylglucosamine, supported by ferulic acid and glutathione. It is a lightweight serum that layers easily, helping post-blemish marks, dark spots and dullness look visibly faded over time for a brighter, more even complexion.

✨ Why You'll Love It

  • Alpha-Arbutin 2% – Helps visibly fade dark spots and discolouration
  • Tranexamic Acid – Targets the look of stubborn marks and uneven tone
  • Niacinamide – Helps brighten and even out the complexion
  • N-Acetylglucosamine – Works alongside the other actives to help skin look more even
  • Ferulic Acid & Glutathione – Antioxidant support for a brighter-looking glow

Best for post-blemish marks, dark spots, sun-related discolouration and dull, uneven skin tone.
