Featuring a powerful percentage of niacinamide, the COSRX The Niacinamide 15 Serum helps to visibly brighten, tone, and diminish the look of pores.
Ideal for blemish-prone skin types, the serum is infused with 15% niacinamide, a high concentration to provide optimal efficacy of the active. The multi-benefit formula is fortified with zinc PCA to minimise the appearance of excess oils and sebum, encouraging a more mattified, yet radiant result. Acetylglucosamine helps to gently exfoliate the skin to reveal a refreshed complexion, while allantoin keeps the skin quenched with moisture.

What a game Changer!
I originally got the COSRX Niacinamide 15 Serum for my boyfriend, and OMG, the results were amazing! Even after just a few days, I noticed a big difference - his pores practically vanished after a few weeks, and his skin started looking better than mine! Of course, I had to get one for myself. The serum is great, absorbs fast without any sticky feeling, and layers perfectly with other products. Definitely worth a try if you want smoother, clearer skin!

Prevents spots
I’m on my second bottle of this now - it’s so effective for calming my combination skin and preventing spots. I also find it gentle - it’s never once caused irritation even though I use most days.

Really pleased with results!
I use this along with other products from same brand & have been really pleased with results! Can be a bit stingy when first put on clean skin but it soon calms down - not a real surprise considering job it does - no inflamed skin either!
