Cosrx The Niacinamide 15 Serum | Pore & Oil Control Serum – 20ml

COSRX The Niacinamide 15 Serum is a high-potency pore and oil control serum designed to improve overall skin clarity and texture. It is formulated with 15% Niacinamide, a powerful concentration that helps visibly minimize pores, regulate excess sebum, and support a smoother, more even-looking complexion. This makes it especially effective for oily, combination, and acne-prone skin, while still being suitable for other skin types when used correctly.

The formula is enriched with N-Acetyl Glucosamine (NAG), which works alongside niacinamide to support pore refinement and improve skin texture, and Zinc PCA, known for its oil-balancing and skin-soothing properties. It also contains Allantoin, which helps calm the skin and reduce the likelihood of irritation, making the serum more comfortable for regular use. Together, these ingredients are carefully balanced to deliver strong results without an overly heavy or greasy feel.

This serum is lightweight, fast-absorbing, and non-sticky, allowing it to layer easily with other skincare products. It is formulated to target common concerns such as excess shine, uneven texture, visible pores, and congested skin, helping oily and acne-prone skin look clearer and more refined over time. With consistent use, skin appears smoother, more balanced, and healthier-looking.

How it helps different skin types

• Oily & acne-prone skin: Helps control excess oil, reduce the look of pores, and improve overall clarity
• Combination skin: Balances oil in the T-zone while maintaining skin comfort
• Normal skin: Improves texture and pore appearance when used in moderation
• Sensitive skin: Can be used carefully with gradual introduction due to high niacinamide strength

Cautions & usage tips
