It was really the worst for me ㅠ My skin is still bad.

This product is called COSRX The Vitamin C 23 Serum. I bought it a little over a month ago and have used it about 6-7 times.

I had heard that Vitamin C serum can sting a little when you first use it, so I started using it with that in mind, but I found the stinging to be quite strong. Honestly, I didn't like the smell either. Then, as I continued using it, my skin started peeling slightly. I thought, "This isn't right," so I stopped using it. I can't believe my skin broke out to the point of peeling even though I hadn't used it for very long. It was a waste of money, and I will never use it again nor recommend it.
