This high-performance serum stands out due to its elevated concentration of niacinamide, one of the most well-researched ingredients in dermatology for improving uneven skin tone, strengthening the skin barrier, and refining texture. While many serums use niacinamide at lower percentages, COSRX delivers a potent 15% dose for faster, more visible results in treating blemishes and reducing discoloration.
Unlike harsh spot treatments, this formula works gently over time to regulate oil production, calm inflammation, and fade post-acne marks without drying the skin. The inclusion of zinc PCA supports anti-bacterial action and oil balance, while allantoin and acetyl glucosamine help maintain hydration and smooth the skin’s surface.
COSRX, a global leader in K-beauty and science-backed skincare, is known for formulating effective solutions using minimal, skin-safe ingredients. This serum is free from parabens, artificial fragrances, and alcohol, ensuring it meets the needs of sensitive and breakout-prone skin without compromise.
Whether you’re managing active breakouts, dark spots, or persistent redness, COSRX The Niacinamide 15 Serum is a targeted, high-strength solution that brings visible clarity and improved skin tone with continued use.
