비타민 고농축이라니 한번써봐야겠네요
COSRX The Vitamin C 23 Serum is said to be a highly concentrated serum containing 23% pure Vitamin C. I was looking for a highly concentrated product because I wanted to see significant results, and this one is reasonably priced. I was worried that a highly concentrated vitamin product might be too irritating, but it wasn't very irritating, so I recommend it.
