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.

Personally I didn’t notice a difference but I also don’t have that much hyperpigmentation. Expires in 2 months

Sticky, I have put this in the fridge as I read previous review. It is easy to go off. No reaction, great product
