COSRX The Alpha-Arbution 2 Discoloration Care Serum 50ml is a targeted brightening and spot-correcting serum designed for users with hyperpigmentation concerns (sun spots, melasma, post-acne marks, dullness) or those needing "gentle yet effective brightening"—core positioning is "5% alpha-arbutin intensive spot care + niacinamide barrier repair + 24h long-lasting hydration".
Its key advantages lie in triple-effect brightening formula (5% alpha-arbutin + 2% niacinamide + adenosine) and lightweight watery texture: The texture is a clear, non-sticky liquid that absorbs quickly (within 10 seconds) into the skin, making it suitable for all skin types—even oily and sensitive skin. Unlike high-concentration vitamin C serums that may cause irritation, it uses alpha-arbutin (a gentler alternative to hydroquinone) to inhibit tyrosinase activity (the key enzyme in melanin production) at the source, reducing existing dark spots and preventing new pigmentation.
The 2% niacinamide in the formula not only enhances the brightening effect by blocking melanin transfer to skin cells but also strengthens the skin barrier, reducing sensitivity caused by external factors (e.g., UV rays, pollution). Adenosine further soothes the skin, relieving dryness and redness, while hyaluronic acid provides multi-layered hydration to avoid the "dryness" often associated with brightening serums.
It is free of alcohol, synthetic fragrances, synthetic dyes, parabens, mineral oil, and hydroquinone, has passed dermatological sensitivity tests, and is certified by the Korean Brightening Cosmetics Association. The minimalist transparent bottle with a dropper applicator ensures precise dosage control and hygienic use, avoiding contamination from hand contact.
Key features:
- Intensive spot care: 5% alpha-arbutin targets melanin at the source.
- Gentle brightening: Suitable for sensitive skin, no irritation or dryness.
- Barrier repair: 2% niacinamide strengthens the skin’s protective layer.
- Long-lasting hydration: Hyaluronic acid keeps skin moisturized while brightening.
