COSRX Alpha Arbutin 2 Brightening Serum is a high-performance formula engineered to visibly diminish dark spots, hyperpigmentation, and uneven skin tone. Powered by a potent 2% concentration of pure Alpha-Arbutin alongside Niacinamide, it inhibits melanin production at the source to fade sun damage and post-breakout scars. The lightweight, fast-absorbing watery serum deeply hydrates the skin with Hyaluronic Acid while promoting a clearer, more luminous, and uniform complexion without causing irritation.
