COSRX The Niacinamide 15 Serum – Target Blemishes, Control Sebum & Brighten Skin ✨

Say goodbye to stubborn breakouts and uneven skin tone with the COSRX The Niacinamide 15 Serum, a power-packed treatment serum formulated with 15% Niacinamide (Vitamin B3) to visibly reduce blemishes, regulate oil production, and refine pores. Blended with Zinc PCA, Allantoin, and N-Acetylglucosamine, this serum offers a comprehensive solution to acne-prone and oily skin, while also improving skin texture and clarity over time.

This potent yet non-irritating formula is ideal for those looking to tackle persistent blemishes, excess sebum, and post-acne marks without drying or stripping the skin.

🌿 How to Use:

1️⃣ After cleansing and toning, apply 2–3 drops to your entire face or focus on troubled areas.
