Product Description
Meet COSRX The Niacinamide 15 Serum, a highly concentrated formula designed for total acne care. The star ingredient is 15% niacinamide, paired with balancing and soothing helpers to support clearer-looking skin and a more even overall tone. Boots describes it as non-comedogenic tested, so it’s made to work without clogging pores.
What you can expect is an oil-control and pore-refining approach: the brand highlights that it helps regulate sebum, minimise the look of enlarged pores, and support smoother texture. In clinical results (20 subjects), Boots notes improvements in activated sebaceous glands, oil synthesis, blackheads and whiteheads over four weeks, as well as visible improvements linked to pigmentation and redness.
Key ingredients include 15% niacinamide, N-acetylglucosamine (NAG), and zinc PCA, alongside allantoin and moisturising trehalose. This combination targets the look of post-acne marks and helps keep skin feeling comfortable while the serum works to clarify and balance.
