COSRX The Niacinamide 15 Serum 20ml – Pores & Oil Control

Description

Refine the look of enlarged pores and help balance excess oil with COSRX The Niacinamide 15 Serum 20ml, a lightweight facial serum formulated for oily, combination and blemish-prone skin. With a concentrated 15% niacinamide formula, it helps improve the appearance of uneven skin tone, visible pores and rough texture.

Niacinamide (15%) helps control excess sebum and promote a clearer, smoother-looking complexion. Zinc PCA complements the formula with oil-balancing care, while N-Acetylglucosamine (NAG) works alongside niacinamide to help reduce the appearance of post-blemish marks and uneven tone.

Enriched with allantoin, the serum also provides soothing care for skin that feels stressed or uncomfortable. Its light, refreshing texture absorbs quickly without a heavy or sticky finish, making it easy to layer under a moisturizer or makeup.

Designed for a simple, targeted skincare routine, this non-comedogenic-tested serum helps skin look more balanced, refined and radiant with consistent use.

• 15% Niacinamide: Helps visibly refine pores, balance excess oil and improve uneven-looking skin tone.

After cleansing, apply a few drops during the serum step of your skincare routine. Gently massage from the centre of the face outwards until absorbed, then follow with a moisturizer. When used in the morning, apply a broad-spectrum sunscreen with SPF 30 or higher. Because this is a concentrated serum, patch-test before first use and avoid direct contact with eyes.
