Star5 qty I love this product
fol...@ COSRX Vitamin C serum has a slightly oily feel; not too thick, not too watery. It absorbs into my skin just as quickly as it is applied which is a huge bonus to me. I have previously used The Ordinary Ascorbic acid 8%+ Alpha Arbutin 2% which has a more oily texture and takes more time to absorb. I have a comparison right here if you’re curious. I noticed some tingling upon first application only. I have used this product every morning before my sunscreen since I have received it. I have noticed significant change in the overall brightness of my skin since incorporating this product into my routine. I loved the product so much that I already repurchased it.

Star4 qty High percentage w/ gentle formulation
fly...@ My second favorite Cosrx serum has to be the Vitamin C 23 serum. This was my first time dabbling in a high percentage vita C serum. I had no problems; however, I do not have very sensitive skin so take it with a grain of salt. I have only used this sparsely since I have been in the sun a lot. Every time I used it in my PM routine, I had no irritation or reaction. I did notice a mild bit of purging after so first used it. I love that this formulation also contains many great hydrators, panthenol, squalane, and sodium hyaluronate. I find it’s slowly helping reduce my hyperpigmentation. I will have to produce an update when I have to finish the serum in 2 months! My only big qualm with this serum is it’s very tacky. Thanks to my Instagram friends I find the best way to use this serum and reduce the tackiness factor is by adding this product first before toner.
