I was really happy to buy into Charlotte Cho's collaboration with Cosrx for the Triple C Lightning Liquid. I've been using this vitamin C serum for 2 months now and love it! Compared to the klairs vitamin drop, this is non-sticky and not shiny. I also like the fact that this comes in black bottle which means it's harder for the serum to discolor.
I only apply the serum at night after eye cream but before moisturizer. I've applied it to my scar above my eye and it's starting to heal better.
Where to Buy: Sokoglam
