This serum is the best serum ever ! I was never disapointed with CosrX, the product give me a nice healthy clean glow. I have less breakout.

holy grail
I am in love with this vitamin serum! I have tried other vitamin C or brightening serums from several other brands but never saw much difference. I am on my 5th bottle of the cosrx one and I love it. I do see my dark spots fading. For deeper scars or pigmentation that's been around for year, it doesn't get rid of them as easily. The color is a bit more yellow than other vitamin C serums but it is a higher percentage. The smell isn't too strong.
