Dramatically lower overactive oil production and clear out stubborn structural congestion with COSRX The Niacinamide 15 Serum 20ml : Niacinamide 15, a high-potency clinical treatment engineered for acne-prone, oily, and highly troubled complexions. Powered by a maximum-tier concentration of pure vitamin B3, this clarifying solution targets active breakouts, fades persistent post-inflammatory dark spots, and tightens visibly stretched pore profiles. Its weightless, fast-absorbing fluid delivery mechanics target structural sebum pathways to intercept blemishes early—leaving an oil-heavy, congested, or uneven combination canvas feeling exceptionally smooth, balanced, and thoroughly clear.

  • Target Concerns: Chronic Acne Breakouts & Blemishes, Enlarged & Stretched Pores, Excessive Midday Sebum, Post-Acne Marks & Redness, Rough Surface Irregularities
  • Skin Compatibility: Highly optimized for oily, combination, and acne-prone skin types requiring intensive sebum control (Sensitive profiles should patch test due to high clinical potency).
  • Texture & Finish: A crisp, ultra-light fluid texture with a clean, smooth slip. It sinks completely into the skin envelope within seconds, establishing a fresh, completely matte-satin finish with absolutely zero sticky residue, greasy weight, or film.

Transform your daily hydration architecture and shield your skin envelope from recurring breakout cycles with a high-performance clinical concentrate designed to elevate baseline clarity safely. When excessive sebum production combines with sluggish cell renewal, follicle walls expand and become trapped with debris, creating the perfect environment for acne-causing impurities to thrive. Standard blemish treatments often rely on aggressive, drying alcohols that strip away essential surface lipids, leading to a compromised protective mantle and a frustrating surge in defensive rebound oil. COSRX The Niacinamide 15 Serum 20ml : Niacinamide 15 bypasses this irritation framework by wrapping a non-comedogenic, oil-modulating formula in a deeply supportive soothing compress.

The bedrock of this advanced corrective solution relies on a targeted 15% Niacinamide concentration, a clinical peak percentage optimized to interrupt complex acne pathways, brighten stubborn pigment shadows, and reinforce physical barrier density simultaneously. To maximize the clarifying process, the formula incorporates Zinc PCA, a bio-compatible mineral compound that directly regulates oil synthesis and keeps aggressive T-zone shine under control. Supported by Acetyl Glucosamine (NAG) to softly lift old surface proteins and unblock tight pore recesses, this dermatologist-tested serum systematically converts a bumpy, oil-congested face into a deeply resilient, uniform, and beautifully balanced complexion.

  • Clinical Peak 15% Clarifying Core: Delivers a highly concentrated dose of pure Niacinamide to flatten active breakouts, balance oily pathways, and refine texture irregularities.
  • Synergized Zinc PCA Oil Regulation: Harnesses advanced mineral binders to minimize excess sebum output and clear out the look of stretched, dilated pore openings.
  • Post-Acne Mark Dismantling: Combines Vitamin B3 with Acetyl Glucosamine to concurrently block dark pigment migration and fade red or brown acne scars.
  • Non-Comedogenic Barrier Comfort: Infused with pure Allantoin to cool down localized skin heat, soothe micro-irritations, and prevent the dry peeling common with heavy acne treatments.

Key Ingredients

  • Niacinamide (15%): A powerhouse clarifying vitamin that controls sebum output, brightens dull post-breakout scars, and reinforces the physical outer lipid matrix.
  • Zinc PCA (1%): A skin-compatible mineral complex that regulates daily oil flow, tightens pore appearance, and provides advanced anti-blemish support.
  • Acetyl Glucosamine: A skin-identical amino sugar that acts as an ultra-gentle, non-acidic exfoliant to lift dead cells and smooth rough skin micro-relief.
  • Allantoin: A reliable anti-irritant that protects vulnerable layers, accelerates cell recovery, and reduces surface redness.

  • Step 1: Use daily during your morning (AM) and evening (PM) routines after completing your initial cleansing and toner layers.
  • Step 2: Dispense 2 to 3 drops of the fluid serum onto your palms or directly onto your face using the dropper.
  • Step 3: Smooth the formula evenly over your facial contours, focusing closely on congested or oily zones like the forehead, nose, and chin.
  • Step 4: Pat softly with your fingertips to encourage quick absorption, then layer your preferred daily moisturizer to seal the active matrix in place.

✨ Pro-Tip: Because of the exceptionally high 15% concentration of Niacinamide, white crystal residues may occasionally appear around the bottle neck or on the skin if too much product is applied. Simply follow up with a generous layer of moisturizer to smoothly dissolve the micro-crystals and optimize delivery.
