This product came highly recommend and now I have multiple bottles and never go a day without it. It’s helped my redness significantly and it’s not too harsh for my sensitive skin.

I can’t say enough good things about this vitamin C serum! Not only does it effectively brighten my skin and reduce dark spots, but the addition of vitamin E and hyaluronic acid makes it incredibly moisturizing. My skin feels deeply hydrated and plump after each use, and the fine lines have noticeably diminished. The serum absorbs quickly and leaves my skin feeling smooth and refreshed, without any greasy residue. I’ve seen a significant improvement in my complexion—more even-toned and radiant. This serum has quickly become a staple in my skincare routine, and I highly recommend it to anyone looking for a multi-benefit serum that delivers visible results!

I have sensitive skin and this formulaic blend of 23% vitamin c by Cosrx does not sting or burn my skin. I needed vitamin c and happy to use this as I am seeing results in 2 weeks It also have vitamin e and hyaluronic acid. I need all the help I can get with my dull, aging skin and this works for me. I like the absorbency, ready for the emulsion after this serum, it’s moisturizing and the dropper makes it easy to apply. Works and doesn’t smell, and I keep it in the fridge. A++++
