Cosrx, Niacinamide 15 serum (20ml)

The Niacinamide 15 Serum is a highly effective serum that works to reduce blemishes, balance sebum production and improve skin texture. With a whopping 15% niacinamide, the serum helps reduce the appearance of pores, even out skin tone and give a clearer and more even complexion.

The formula is enriched with N-acetylglucosamine (NAG) and zinc PCA, which strengthen the skin's barrier and soothe irritation, while allantoin and panthenol add moisture and reduce redness. Together, they provide a more balanced, glowing and healthy skin without drying out.

Active ingredients:

Niacinamide (15%) – reduces pores, balances sebum and improves skin tone.

N-acetylglucosamine (NAG) – works in synergy with niacinamide to brighten and refine skin texture.

Zinc PCA – has antibacterial properties, reduces impurities and regulates sebum production.

Allantoin & Panthenol – soothes and moisturizes the skin, reduces redness and irritation.

The result is a more even, calm and clear skin with refined texture and natural glow.
