COSRX The Niacinamide 15 Serum 20ml

🧪 15% Niacinamide To Erase Stubborn Dark Spots

This maximum clinical dose works aggressively to block melanin transfer and even out skin tone. Its intensive clearing action quickly fades hyperpigmentation and post-blemish scars, restoring a uniform brightness across your complexion.

⚓ Zinc PCA To Regulate Overactive Sebum Production

Zinc PCA acts as a powerful structural regulator, physically suppressing excessive oil production within your pores. By maintaining a clean moisture balance, it dramatically reduces midday grease and prevents future acne blockages from forming.

✨ Acetyl Glucosamine To Refine Surface Textures

Working in perfect synergy with Niacinamide, Acetyl Glucosamine gently exfoliates dead cells to prevent congestion. This mild structural polishing smooths out rough skin and shrinks enlarged pores, leaving your surface look polished.

How to Use

1. After cleansing and applying a lightweight toner, dispense 2 to 3 drops of the serum directly onto your fingertips.
2. Gently smooth the concentrated fluid across your face, focusing heavily on your oily T-zone.
3. Pro Tip: For a total oily skincare routine, pair this with the COSRX Oil Free Ultra Moisturizing Lotion as your final step.
   The birch-sap lotion locks in breathable hydration, while the Niacinamide serum physically controls grease, creating a powerful duo against afternoon shine.
