didnt notice a huge difference
Definitely one of the hit product of Cosrx, very hydrating, with prolong use could see disappearance of sun spots. Also improved skin texture.
Wasn't bad overall. It did dry out my skin quite a bit, however i did notice less whiteheads and my acne somewhat decreased in the 2 month span that I used it. I now use it on occasion if i feel like my skin needs it but not ever day.
