My Go To Vitamin C
[This review was collected as part of a promotion.] Another COSRX product that I can't live without. It's the only Vit C I use and will continue to purchase. I did try the Vit C 23 but I definitely like how this one works on my aging skin better.

This is so soft and
[This review was collected as part of a promotion.] This is so soft and even on the skin. Does feel a bit sticky towards the end of application but if you let it dry into the skin that goes away. The scent is different, I won’t lie, but doesn’t linger post application. I have noticed lightening in my melasma since starting CosRx products, but I am using multiple products, so most likely from the combination of all. Great size bottle for the price. It is only 13% pure vitamin C, but it is helping with brightness.
