Benefits

The COSRX The Niacinamide 15 Serum provides targeted care for various skin concerns, including excess oil, visible pores, and blemishes. By regulating sebum production and addressing the stages of skin trouble—from excess oil secretion to post-trouble marks—it helps achieve a clearer, more balanced complexion. Regular use helps refine skin texture, reduce the appearance of blackheads and whiteheads, and promote a more uniform skin tone by addressing redness and pigmentation.

Main Ingredients and their effects

Niacinamide (15%): A highly effective ingredient that helps improve skin tone, enhances the skin barrier, reduces sebum, and minimizes the appearance of pores. Acetyl Glucosamine: Works in synergy with Niacinamide to improve skin texture and address blemish marks. Zinc PCA: Helps control excess oil and provides sebum care to maintain a balanced complexion. Allantoin: Included to soothe and protect the skin.

Clinical test results

Based on a study conducted by the Derma Cosmetic Skin Science Research Institute (September 3, 2022 – October 4, 2022) with 20 adult men and women aged 14–50, the COSRX The Niacinamide 15 Serum demonstrated significant improvements after 4 weeks of use. Results showed a 45% reduction in sebum, a 48% reduction in oil, a 42% decrease in blackheads, and a 50% decrease in whiteheads. Additionally, the serum showed a 15% improvement in pigmentation and a 19% improvement in blemish marks. Skin tone improvements included a 24.8% reduction in redness and an 11.7% reduction in yellow skin tones.

Usage instructions

After cleansing and applying toner, dispense an appropriate amount of the COSRX serum onto the face. Use your fingertips to gently roll the product from the inside of the face outward until fully absorbed. While this serum can be used both morning and evening, it is essential to apply a sunscreen with SPF 30 or higher when using the product during the morning routine to protect the skin. Due to the high concentration of active ingredients, please note that small amounts of the ingredient may occasionally appear at the bottle opening if exposed to air; this is a natural phenomenon and does not affect the quality or safety of the product.
