Review: Love it love it best vit c - 5-Star Review: The COSRX Vitamin C23 serum is an absolute powerhouse! Packed with Vitamin E and hyaluronic acid, it has transformed my skin. As someone with Indian skin living in the UK, I’ve struggled to find a serum that absorbs well, but this one works beautifully. It sinks right in, leaving my skin hydrated, radiant, and noticeably improved. Yes, there’s a slight smell when you first apply it, but it fades almost instantly. Honestly, it’s a small trade-off for the incredible results. My skin feels smoother, more even-toned, and healthier overall. I’m just loving it and can’t recommend it enough! Review: No issue with dry, sensitive skin - This is the first time I’ve used this particular product from COSRX. I thought I’d give it a try because it was at a very good discount for black friday. I’ve got dry sensitive skin and minor rocesea so was a bit worried if I’d get any reaction from it but my skin was fine. I do put cosrx advance snail mucin first and then apply the vitamin C. It does have a weird smell as mentioned by others but I don’t mind it because as soon as you’ve applied it onto your skin the smell is gone so not sure why people are making such an issue out of it. I’ve been using it for a couple of days now and my skin seems to like it and I notice my skin is brighter and soft even after a nights sleep. ## Features - The Vitamin 23% Serum: Create the best synergy.
