Good stuff with a good price!
This stuff is so good! It has a slightly woetd smell but my dermatologist said that if your vitamin c serum doesnât smell like bologna, it isnât good vitamin c. The smell goes away pretty fast after applying. I just Iâll my breath for a for seconds while I put it on and then itâs gone.My skin looks so healthy and glowing since k started. I am shocked with such good results at su h a good price. You HAVE to keep it refrigerated after opening though!!

Love it
I waited until I finished a bottle before reviewing, I really love this product. Itâs definitely a heavier serum but soaks into the skin nicely. Vitamin c serum helps to keep my skin clear and it helps with texture a lot, too, and this serum helps a lot with those things. There is definitely a strong smell but once itâs applied the smell goes away quickly so I donât think itâs a negative thing necessarily. I like that this serum has a higher concentration than a lot of other ones by like 10% so itâs hard to beat as far as how much actual vitamin c is in it. Highly recommend!

It’s pretty good!!
Ive bought this product Twice so far and i do have to say that it is pretty effective it leaves the skin feeling pretty smooth and you 100% see a difference when it comes to darkspots, it helped mine fade quite a bit while using it and it makes the skin feel very smooth after a little bit of using. the only thing i need to mention is that this NEEDS to be paired with a good moisterizer after use or else it will leave your skin felling sticky and gross and a little itchy some times from the irritation it brings. Its also needed to mention that this product does have a strange smell, obviously not a bad smell but just a weird one from the mixture of the products in it, i wouldnt say thats a bad thing though because its good to have products that dont have added fragrence and just be left with its natural one. Besides thoes two things i think this is a really good product and i will be buying it again because it is very effective.

Instant Glow
Iâve only used this product for a few days, but I can already tell a difference, which is crazy. As soon as I put it on, it gave me an instant glowânot oily, greasy mess kind of glow, but the healthy, plump kind of glow. As someone who had beautiful skin during pregnancy, but is now struggling with uneven and dull skin tone postpartum, this made me extremely happy. Anyway, here are my initial thoughts:Formulation:â¢this contains a high ascorbic acid percentage. Iâve never been sensitive to ascorbic acid, so my skin does well with the high concentration. However, if you have more sensitive skin, consider starting with their other vitamin c serum that has a lower percentage of vitamin c.â¢there is no ferulic acid present, which is generally used to stabilize ascorbic acid. Without this, Iâm afraid the product wonât last terribly long without oxidizing, so keep this in mind. The instructions do say to refrigerate after opening, which may help slow down oxidation.Texture:The texture of this serum reminds me of a bi-fácil product where there is an oil layer and water layer that need a little shake to incorporate. Donât let the oiliness scare you though, it does sink in to the skin well and doesnât feel heavy on the skin. I havenât had any issues with pilling when Iâve applied other products and makeup on top.Smell:As many reviewers have mentioned, it does have a particular smell to it. To me, it reminds me of tuna, which is quite unpleasant. However, it does dissipitate quickly. I just hold my breath while I apply it to my face XD I don’t smell it at all throughout the day.

Did this make me sick?
After showering on a Friday evening, I applied the serum to my face. The smell was absolutely disgusting, but I was prepared for that having read the reviews. I had no negative skin reactions. A couple of hours later I started to get a headache. I took some ibuprofen, put the heating pad on my head, and went to sleep. I woke up at 3am with a terrible headache and I felt nauseous. I want to note that I get frequent migraines and that this was not a migraine headache. It was a painful tightness all around the top of my head. Also, I realized that the heat from the heating pad was reactivating the smell of the serum on my face, which was really gross. When I finally tried to get up and move around at 7am it was awful. I felt like I had the stomach flu. Sweating, shaking, nauseous. And then I threw up. I really did think I was sick and didnât even consider the serum until a few hours later. I talked to my sister and mentioned my thoughts about the serum. She suggested that I take a long hot shower to try and get it all off of me and to change my bedding. So I did, and by the end of Saturday I was feeling not 100% but so much better. I havenât seen any other reviews that mention this type of reaction. I tried googling it too and found nothing, so obviously this could be some kind of weird coincidence that I got sick for a short time while trying to use this product. Either way, Iâm too scared to try it again. The smell alone might make me sick anyway. Good luck!

Iâve used various expensive vitamin c products for a few years but this is the first one that made me do a double take after I caught a glimpse of my reflection.Keep in the fridge as recommended.Yes, there is a small odour but it fades over time.My skin is slightly sensitive and the first application burned but it got better in a few days.

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, Iâve 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, thereâs a slight smell when you first apply it, but it fades almost instantly. Honestly, itâs a small trade-off for the incredible results. My skin feels smoother, more even-toned, and healthier overall. Iâm just loving it and canât recommend it enough!

I have sensitive and oily skin. This serum is gentle on my skin. I had to use it first for three weeks before leaving a review. The product was delivered with care.
