From the first time I used this there was a visible difference in the texture of my skin the next day! Especially on my forehead it is a lot smoother than it used to be! I love this!

One of the issues I'd read was people complaining about the smell saying that it smelt like fish? I have to say I have not experienced that AT ALL, so unless COSRX have changed the formula or something I think it's just that some people might be more sensitive to smells or maybe I'm just bad at picking up smells haha I honestly cannot smell anything (good or bad) when I use this. So don't let that prevent you from buying this!!

Also I find that one pump is enough for my entire face, so I expect this to last quite a long time! definitely making it worth the money. The packaging is also very sturdy and simple.
