COSRX AC Collection Blemish Spot Clearing Serum 40ml — Centella & Niacinamide Soothing Treatment

COSRX AC Collection Blemish Spot Clearing Serum is a lightweight, fast-absorbing treatment serum designed to calm, clarify, and help fade post-acne marks using centella-derived actives, niacinamide and EGF.

This concentrated 40 ml serum targets problematic, acne-prone skin with a soothing CentellAC‑Rx Complex, niacinamide for tone correction, and EGF for skin recovery support. The formula is tailored to absorb quickly without tackiness, leaving skin feeling refreshed and less irritated. COSRX positions it as a gentle yet focused step in a corrective routine, suitable for oily and sensitive complexions that need targeted blemish care without harsh ingredients.

How does this serum help calm and clear breakouts?

The serum centers on a CentellAC‑Rx Complex composed of centella-derived molecules known for their soothing properties, combined with niacinamide to even skin tone. These actives work together to reduce visible irritation and support the skin’s return to a calmer state. It’s formulated to leave minimal residue so acne-prone skin can breathe.

• CentellAC‑Rx Complex (madecassic acid, asiaticoside, asiatic acid) for calming
• Niacinamide to help brighten and even discoloration
• EGF to support skin recovery and renewal
• Lightweight texture that absorbs quickly without stickiness

When and how should I use the serum in my skincare routine?

Apply the serum after cleansing and any water-based treatments (toner or essence) and before heavier creams or oils. Two to three drops provide adequate coverage; gently spread and massage over the face, avoiding the eye and mouth areas. Use morning and/or evening as needed, and follow with sunscreen in daytime routines.

• Use after cleansing and toning for best absorption
• Two–three drops, spread evenly across the face
