WELCOME SHINE BRIGHT SKIN
i've been tried this serum for about 1 weeks day and night. i didnt get any negative experiences when i used the product. after a week used i can see my pores got smaller, my skin texture became smoother and firm than before, i'll continue the usage to make sure another claim. for you all who've been obsessed with niacinamide absolutely should try this product. you can get this product in their official online or offline store to make sure you get the original.

Can't wait to try
I ordered this serum along with their vitamin c serum because niacinamide and vitamin c is a match made in heaven, so I have my hopes high, cosrx never disappoints..will update

BEST FOR SKIN TEXTURE
a watery serum that has a very cute dropper. no hint of scent and is easily absorbed by my skin too. I didn't experience any irritation even it has a high percentage of niacin. Also, nice if you are focusing on pore and acne care.
