COSRX’s AC Collection Blemish Spot Clearing Serum targets active breakouts while helping post-blemish marks look less noticeable, using niacinamide, Madecassic Acid, Propolis Extract, and CentellAC-RX to calm visible redness and support a clearer-looking complexion. Tea tree leaf oil with asiaticoside and asiatic acid helps reduce excess oil and soothe the look of inflammation, making it a practical choice for acne-prone skin that needs focused spot care. Barrier-supporting Ceramide NP and panthenol help reinforce skin that feels stressed from blemishes, while sodium hyaluronate and hyaluronic acid deliver lightweight, lasting hydration to minimize dryness and flaking. With steady use, the cruelty-free, paraben-free formula helps skin appear more even, comfortable, and resilient where breakouts tend to linger.
