Perfect combination of ingredients and does what you would expect.

I will write again when I will use it. I hope that doesn't irritates my skin.

A powerful vitamin C serum that doesn't irritate the skin. I use it before sunscreen in the morning.

I have used vit c serum from very expensive brands and I found this serum is the best , I love it. Thank you.

I liked this serum, It was nice on my skin and I love cosrx products so much!

There's a reason why these are so popular in korea! It applies so smoothly on the skin without any irritation. I have sensitive skin but these worked so well for me.

I have watched YouTube video to recommend this product. I hope it will work for me to brighten my skin.
