The COSRX The Niacinamide 15 Serum is a lightweight, high-strength niacinamide serum that comes in a 20ml bottle with a dropper. It is a minimalist 15-ingredient formula built around 15% niacinamide, 2% acetyl glucosamine (NAG), and 1% zinc PCA, plus allantoin and vitamin E. The watery, fast-absorbing texture targets excess oil, the look of pores, and post-blemish marks, and sits at the serum step of a routine for morning or evening use.

OVERVIEW

If your skin gets oily or shiny and you're dealing with the look of enlarged pores or leftover marks from breakouts, a high-strength niacinamide serum is a targeted way to help balance things out. This COSRX niacinamide serum uses a concentrated 15% niacinamide to help refine the look of pores, even the look of tone, and keep excess oil in check. It has a lightweight, watery texture that absorbs quickly and layers cleanly.

What makes this niacinamide serum such an effective, no-fuss pick is its focused, minimalist formula. A high concentration of niacinamide (15%) is paired with 2% acetyl glucosamine to help smooth the look of texture and even tone, 1% zinc PCA to help balance oil and support clearer-looking skin, and allantoin to soothe. With just 15 ingredients and no fragrance, oils, or silicones, it is designed to be effective while staying gentle on the skin barrier.

This serum suits most skin types and is an especially nice fit for oily, combination, or blemish-prone skin that wants to target shine, the look of pores, and post-blemish marks. Use two to three drops after cleansing, morning or night, and always follow with sunscreen in the daytime. One honest note: high-strength niacinamide can feel tingly or too active for very sensitive skin at first, so start slowly and patch test if you are reactive.

1 Who is the COSRX The Niacinamide 15 Serum best for? A:

It suits most skin types and is especially nice for oily, combination, or blemish-prone skin that wants to target shine, the look of pores, and post-blemish marks.

Q2: Is 15% niacinamide too strong? A:

It is a high concentration, so it is very effective, but very sensitive skin may find it tingly at first. Start with a few times a week, and patch test if your skin is reactive.

Q3: Does it have a scent? A:

It is fragrance-free with no added fragrance or essential oils, and has a minimalist 15-ingredient formula, which makes it a good pick for those who prefer simple serums.

Q4: Can I use it with other actives? A:

Niacinamide layers well with most things. It is generally best to use strong acids (AHA/BHA), vitamin C, or retinol at a different time of day so your routine is not too active at once.

Q5: When should I use it? A:

Use it as your serum step after cleansing and toner, morning or night, before your moisturizer. Always follow with sunscreen in the daytime.
