COSRX- The Vitamin C 23 - 20g

I really do see a difference .. it will give you that glow as vitamin C should even on days I pull an allnighter

This is a pure Vitamin C and, as a result, it has a smell to it when first applied (as mentioned/complained by many). However, this smell dissipates completely and very quickly. Most brands aren't pure, thus they don't have a smell to them. I have used this brand for a couple of years and I like that I get a high percentage of pure vitamin C at a great price, plus it doesn't leave me sticky like many Vitamin C's.

Smell reminds me of some cat food or treats hence why I only use it before bed. By morning reminds me of the smell of self tanners, unless maybe it's all in my head and it still smells (no one has said anything to me yet). Haven't used it long enough to see any benefits but my skin tends to love anything cosrx.
