COSRX The Niacinamide 15 Serum 20ml / 0.67 fl oz

COSRX The Niacinamide 15 Serum 20ml

A high-strength, skin-friendly serum with 15% Niacinamide to visibly minimize the look of pores, balance excess oil, even skin tone, and refine rough texture—without heaviness or stickiness. The fast-absorbing formula is designed for daily use on oily, combination, and blemish-prone skin.

Key Benefits

• Pore look reduction and smoother-looking texture with daily use
• Oil and shine balance across T-zone and cheeks
• Tone-evening support to improve the look of post-blemish marks
• Lightweight hydration with a clean, non-sticky finish under makeup
• Gentle daily use suitable for sensitive and acne-prone skin

Why It Works

Niacinamide is a multi-tasking active that helps regulate excess sebum, refine the look of enlarged pores, support an even tone, and reinforce the skin barrier for better moisture retention. The serum’s water-light texture layers seamlessly in routines and pairs well with barrier-supporting humectants and emollients.

How to Use

1. After cleansing and toner, apply 2–3 drops to face and neck, focusing on oily or uneven areas.
2. Press to absorb and follow with moisturizer. Use morning and/or evening.
3. If using strong actives (retinoids/AHAs/BHAs), alternate days or split AM/PM as tolerated. Use SPF in the morning.

Recommended For

• Oily or combination skin with visible shine
• Enlarged-looking pores and uneven texture
• Post-blemish discoloration and dull tone
• Those wanting lightweight hydration without greasiness

Texture & Finish

Water-light serum that absorbs quickly with a fresh, non-sticky finish—ideal under sunscreen and makeup.
